Introduction Contents
These are another excellent set of radios that have many fine features for scanning and trunking. However, anyone who has tried to read the manuals that come with the radios know it can be a little hard (if you're lucky) to find, read, and figure out some of the steps, especially in the searching and trunking sections. IMHO they are a mess.
 
I can’t remember everything and find myself referring back to the manual for explanations of procedures and find it frustrating trying to figure out the wording every time. I decided to write and publish this for myself to make it easier to use the radio and am happy to share it with you. This should also make it easier for most people to use some of the more advanced features of the radio (and get their money’s worth if you paid full-price for the radio new) as I will try to explain procedures a little more clearly and in a more logical order. Granted, these radios aren't simple so you will have to spend some time on them but this manual will at least make it easier. If you follow the red highlighted text in the programming sections, you should find what you need to know. If you want to find out what's really going on with the radio, read everything else.
 
Some of the better features of these radios are the ability to receive tone codes in certain service searches, the seek feature in search mode that resumes searching after 5 seconds, and the adjustable ID delay. IDs can be locked out in open mode (vs. the older Pro-93/2053/94/95). The Skywarn lets you program 3 Skywarn frequencies (or any other conventional freqs) into channels 997-999 for one-touch access to them. The Repeater Finder Tool will help you find the correct LCN for LTR systems. The best one, in my opinion, is the ability to configure everything in the software, on the computer, and then just shoot it to the radio (with a one-way cable) or back to the computer (with a two-way cable). Much easier to work with the keyboard and see the monitor. You can set the attenuator globally or per channel. With a couple of keystrokes, you can view the IDs as text or code. There are 5 ID lists (30 IDs per list) to store 150 IDs for each bank.
 
Now, on the flip side, there are some pretty annoying things about these radios too. They still have preset steps that will not tune to many of the splinter frequencies in the VHF range (except the 108-137 air band) like 151.0125; (it accepts it as 151.01). The Air service search is relatively slow because of the 8.33 kHz steps. Still only 1 priority channel? The backlight goes out long before the batteries die.

An overview of the features can also be viewed at my
Trunking Radio Comparison Chart page.

You will also need a better antenna. The stock rubber duck isn't fabulous. RS has the Center-Loaded Telescoping Whip for $16 - better for VHF/UHF. The 800MHz Scanner Antenna  for $20 - 100% better for 700+ MHz. You may be able to find others on the web but RS is convenient so you can buy it and take it back in the same day if you don't like it. Read the reviews for each at the site.
 
These radios also have software that will enhance and/or enable other features not possible with just the keypad and have been noted when known. My opinion is get the software if you have a lot of frequencies. With all the features and setting in these new fangled devices it will save you hours of programming and frustration. It may also be easier to figure out the software than the keypad sequences. Alpha tagging is great but much easier with the software. Because of the limited amount of keys on the radios, programming a 3 letter word takes about 20 keystrokes on my Pro-97, if you can remember the sequence and don't make a mistake, after you program the bank name. See what I mean? Get the software. You have to dish out $20 bucks or so for a cable, the software is $20-30 (after a 30-day free trial), and there are plenty of newsgroups on the Net about these radios to help you hook up to the computer and work the software.
 
All in all, they will compliment your scanner collection (provided you have one).

I will assume you know how to obtain the basic information from the original manual such as following safety procedures, putting the batteries in, connecting the antenna, finding specs, etc. and concentrate on the main functions of the scanner.
 
I hereby absolve myself from anything that happens to anyone or the scanner as a result of the information you will be reading. You are welcome to copy and/or print these pages and use them in the scanning hobby as long as you don't change, redistribute, or charge/accept money for them.
 
Check back often as this document will be updated and revised from time to time. I have tried the best I can to make sure everything is accurate here but if I missed a step or you see something that's obviously wrong, please email me.

Scanning Terminology Contents
 
Note: To avoid confusion, and to also correct RS, I will be referring to the pre-programmed search ranges as bands and not banks. A band is something you search; a bank is where you store things (like channels). The RS manual will refer to search bands as 'bands'; (correct), 'banks', 'frequency ranges' or 'search ranges' to really confuse people.
Scanning- the process of stepping through conventional channels in scan banks.
Trunktracking (open mode)- the process of searching for all active talkgroup IDs in trunked systems, in scan banks.
Trunkscanning (closed mode)- the process of stepping through programmed talkgroup IDs in ID lists, in trunked systems, in scan banks.
Open and Closed Modes- You search all IDs in Open mode or just programmed IDs in Closed mode.
Pause Mode- the mode the radio is in while paused on a scan; service, limit, or tune search.
Searching- the process of searching for active frequencies in pre-programmed service searches, programmed frequency bands, or the limit search.
Manual Mode- used for browsing and monitoring a channels.
Program Mode- used for storing frequencies, limit searches, priority channels, trunking frequencies/systems/fleet maps, and talkgroup ID lists.
Trunk Mode- used for trunking and programming trunking frequencies and functions.
Clone Mode- used for cloning scanners and uploading/downloading to/from scanners using a computer.
 
At certain times, the radio can be in more than one mode at a time such as program and trunk mode to program trunked functions.

Understanding Trunking Contents
Trunking systems let a large group of 2-way radio users (or even different groups of 2-way radio users) efficiently use a set of frequencies. Instead of selecting a specific frequency for a transmission, the userís radio selects a programmed trunking bank in the system when that user presses their PTT (push to talk) button. The trunking system automatically transmits the call on the first available frequency, and also sends (on a different frequency called a Data or Control channel) a code that uniquely identifies that transmission as a talkgroup ID (or just ID.) So when you are trunktracking a system, you are listening to active IDs transmitting in the system (each using the first available frequency in the system.) Trunking systems in general allocate and use fewer frequencies among many different users.

Since the trunking system might send a call and its response on different frequencies, it is difficult to listen to trunked communications using a conventional scanner. These scanners let you monitor the control channel frequency so you can hear calls and responses for users and more easily "follow" conversations than with a conventional scanner.

These scanners trunktrack the following types of systems:
  • Motorola Type I
  • Motorola Type II
  • Motorola Type IIi Hybrid
  • Motorola Type II Smartnet
  • Motorola Type II Smartzone
  • Motorola Type II Smartzone Omnilink
  • EDACS Standard (Wide)
  • EDACS Networked (Wide)
  • LTR Standard
When you program Motorola and EDACS system frequencies into the scanner, one frequency is the control (or data) channel, and the rest are voice frequencies shared by all the users. There may be 3 or 4 frequencies assigned as (primary or alternate) control channels but only one control channel will be active at a time. These scanners will allow you to program just Motorola control channels into the trunking system and the voice channels will automatically be found (but not programmed). EDACS systems need all the frequencies for the system programmed and in the correct LCN (Logical Channel Number) order.

The control channel is continually transmitted to the field units and has a sound similar to listening to a boat engine over the phone (in manual mode; you won't hear this when you are trunking the system.) This control channel is also a good check to see if you can trunktrack the system. If you can't hear a control channel when you step through the trunking frequencies (in manual mode), you either don't have all the frequencies or are too far away to receive the control channel and the system.
Motorola systems are limited to a maximum of 28 frequencies per system or site. Ericsson EDACS systems are limited to 25 frequencies per system or site. Motorola and EDACS systems can be either analog, digital, or mixed (digital and analog talkgroups). These scanners can't monitor digital systems.

LTR systems work a little differently. LTR systems typically do not have a dedicated control channel.
This type of system encodes all trunking information as digital subaudible data that accompanies each transmission. The frequencies also have to be in LCN (Logical Channel Number) order or the correct 'slot' for the system to trunktrack properly. The Repeater Finder Tool will help you determine the correct order. Each repeater has its own controller, and all of these controllers are synchronized together. Even though each controller monitors its own channel, one of the channel controllers is assigned to be a master that all controllers report to. Each of these controllers sends out a data burst approximately every 10 seconds so that the subscriber units know that the system is there. This data burst is not sent at the same time by all the channels, but happens randomly throughout all the system channels. If you listen to the frequencies of an LTR system in manual mode (not trunking), on every channel in the system you will hear this data burst that will sound like a short blip of static like someone keyed up and unkeyed a radio within about 500 msec. LTR systems are limited to 20 frequencies per system.

Trunkscanning is basically scanning IDs that are programmed into ID locations (same concept as frequencies into channels.) You can then trunkscan just the programmed IDs. Trunktracking is searching for all IDs in a system (same concept as searching for frequencies in a band.)
 
Radio Reference.com has an excellent page explaining the various types of trunking systems in more detail here.

Understanding Banks Contents
Channel Storage Banks
The radios have 10 banks of 100 channels. Channel numbering starts with 000 and goes to 099 in the first bank. Banks number 0-9. You can also program your trunking frequencies and conventional frequencies into the same bank as well to utilize channel space better.
 
Use each channel-storage bank to group frequencies, such as those for police, fire, ambulance, aircraft, and/or trunking systems. For example, your police department might use 20 frequencies while the fire department uses 15 and a trunked EMS systems uses 5 trunked frequencies. You could program the EMS frequencies starting with channel 000, (the first channel in bank 0), the police frequencies starting with channel 005, and the fire department frequencies starting with channel 025. EDACS systems have to start at channels 001, 101, 201, etc. and follow a LCN order but you can still use 000, 100, 200, etc. for a conventional frequency.
 
For each trunking bank, you can put in one EDACS system (with conventional frequencies), or one Motorola system and/or an LTR system (with conventional frequencies). However, if you store a Motorola system and an LTR system in one bank, the bank mode has to be set to MO (Motorola). If it is set to LT (LTR), the Motorola control channel will break the squelch and hang the scanner on that channel.

Also,
(1)
if you scan this bank in open mode, you will hear all Motorola IDs and LTR transmissions (IDs will be incorrect because the bank is set to receive Motorola IDs).
(2) If you scan this mixed bank in closed mode with Motorola IDs programmed, you will hear just the programmed Motorola IDs.
(3) You will hear the data bursts from the LTR system about every 5 seconds so you should set the delay for these channels accordingly.
 
Tip: Theoretically, you could also program more than one (of the same type i.e. Motorola) trunking system into a bank as long as you could only monitor one at a time, in different locations, far enough apart, so the system you are monitoring wouldn't interfere with the other system (which would confuse the radio). But remember, the scanner can be set to decode only one type of ID (MO, ED, or LTR) per bank.

Service Search Bands
The scanners also have 6 service bands pre-programmed with frequencies and 1 limit search to allow you to create your own search band. Search bands SR3 (Police/Fire), and SR5 (Amateur) are divided into groups or sub-bands of frequencies that can be turned on or off within the bands.

Understanding IDs Contents
Motorola IDs come in two formats: Type I and Type II. Each format displays and uses Talk Group IDs in slightly different ways. Type I/II hybrid systems use both Type I and Type II formats for Talk Group IDs.
 
Type I IDs are in the format FFF-SS where FFF is the fleet and SS is the sub-fleet. Type I systems are usually organized with different IDs assigned to different fleets. For example, a valid fleet/subfleet ID identifying all detectives within a police department might be 000-12, where 000 identifies all police IDs and 12 identifies the Detective division. To properly trunk a Type I system, you have to program the fleet map for the system.
Type II IDs are identified by a 5-digit number. Valid (programmable) Talk Group IDs are divisible by 16.
 
EDACS IDs come in two formats: AFS (Agency-Fleet-Subfleet) and Decimal.
 
AFS IDs are in the form AA-FFS where AA is the agency, FF is the fleet, and S is the sub-fleet. EDACS systems are organized with different IDs assigned to different fleets and agencies. For example, a valid agency/fleet/subfleet ID identifying all detectives within a police department in an agency might be 06-101, where 06 identifies the agency (Police), 10 identifies the Police division (East side), and 1 identifies the Detective division.
Decimal IDs are shown as a decimal number from 0 to 2047.
You can find a chart showing Decimal and AFS equivalents here: Conversion Chart.
 
LTR IDS are in the format A-HH-UUU where A is the area code (0 or 1), HH is the home repeater (01-20), and UUU is the user ID (000-254).

Receive Modes Contents
Each channel can have its own receive mode:
AM
, FM (NFM), CT (CTCSS), DC (DCS), MO (Motorola), ED (EDACS), or LT (LTR) mode.
If the receive mode of the channel is set to CT, PL codes appear in the format xxx.x, where xxx.x is a frequency in Hz.
If the receive mode of the channel is set to DC, DPL codes appear in the format xxx, where xxx is an octal code.
AM - Receives AM transmissions. MO - Receives Motorola IDs.
FM - Receives FM transmissions. ED - Receives EDACS IDs.
CT - Receives CTCSS tones. LT - Receives LTR IDs.
DC - Receives DPL (digital private line) tones.  

Understanding CTCSS/DCS  
Continuous Tone Coded Squelch System (CTCSS) and Digital Coded Squelch (DCS) are two methods used to prevent interference by other radio communications. Your scanner can receive transmissions that use these codes (or more commonly referred to as tones).

CTCSS and DCS systems all use some form of coded squelch. Coded squelch techniques involve the transmission of a special 'code' signal along with the audio of a radio transmission. A receiver with coded squelch only activates when the received signal has the correct 'code'. This lets many users share a single frequency, and decreases interference caused by distant transmitters on the same channel. In all major metropolitan areas of the United States, every available radio channel is assigned to more than one user. Public safety radio systems on the same frequency are usually set up at a distance of 40 miles apart, or more. This means that you may hear transmissions from a distant system when your local system is not transmitting. By programming the CTCSS tone for a local channel the scanner will not stop on transmissions from the distant system. With few exceptions, such as the VHF Aircraft and Marine bands, almost every other VHF or UHF radio system uses some form of coded squelch. By far, CTCSS is the most popular mode among non-trunked systems.

For more information visit Radio Reference's respective pages on CTCSS and DCS.

Open and Closed Modes  
Each channel bank can be set to open or closed mode.
In open mode the scanner will receive:

(1) all channels in AM, FM, CT, and DC modes, that are not locked out.
(2) all IDs in MO, ED and LTR modes, even if they are locked out in the ID list.

In closed mode the scanner will receive:

(1) all channels in AM, FM, CT, and DC modes, that are not locked out.
(2) only IDs in MO, ED, and LTR modes that are programmed into the ID list, and not locked out in the list.

In other words,
If you want to hear all IDs, scan in open mode. If you want to hear specific IDs, program them into the scan lists and scan in closed mode. If you want to hear specific IDs and not hear other IDs, program them into the scan lists, lock out the ones you don't want to hear, then scan in closed mode.

Programming Conventional Frequencies Contents
You can program trunking frequencies (1 trunking system per bank) and conventional frequencies into the same bank to utilize channel space better. That way, you don’t have to waste a whole bank on a trunking system that has only 5 channels. I typically put my trunking frequencies in starting at the beginning of the banks because you probably won't have more than 25 of those, and then fill up the banks with conventional frequencies.

Channels start at 000 for bank 0, 100 for bank 1, 200 for bank 2 etc.

If you are going to be programming text tags for the frequencies, I find it easier to program all the frequencies first, then go back and program all the text tags.

To exit programming, press MAN.
 
Programming Tone Codes

 

You can set the receive mode of a (conventional) channel to receive any CTCSS or DCS tone code (if one is transmitted). You can also program a tone code for a channel (frequency) so the scanner will only stop on that channel if the programmed code is received with the frequency (regardless of open or closed modes).
 
To program a channel for CTCSS or DCS search:
1. In Manual mode, select the channel by entering the bank number and channel number then press MAN to advance to the channel.
  Note: You may also change banks by pressing FUNC then or (each time) and then change channels by pressing or .
2. Press MODE until you set the channel to CT Code Search or DC Code Search in the bottom of the display. Usually, but not always, VHF channels will use CTCSS and UHF channels will use DCS. If you leave the channel at this 'Search' setting, the scanner will display the first code (if) found when you do not program a code.
 
To program a CTCSS or DCS tone for a channel:

Programming a Fleet Map Contents
Motorola Type I or Type IIi systems require you to program a fleet map. This allows you to receive the talkgroup IDs correctly. If you don’t know which fleet map to use, you can try a method I found at Radio Reference.com.. Since it is rather lengthy, I will just give you the link. Determining Type I Motorola Fleet Maps by Dave Goodson. If you know the fleet map by name, E1P1, E1P2, etc., I have listed 16 pre-set fleet maps so you can see the size codes.
 
1. In Manual mode select any channel in the bank you want to program the fleet map in (Ex: 001) then press MAN to advance to the channel.
2. Press PGM then TRUNK to put the scanner in program and trunk modes. You will see the ID list and MOT: none.
3. Press FUNC then 8. SizeCode Setting Use Code 15 for Type II Blocks Block 0 SC=00 will appear.
4. Enter the size code for block 0 (ex:8 for S-8). If you make a mistake, press CL to clear the entry.
5. Press ENT to store the size code for the first block and move to the next block. Program the rest of the block codes the same way. The ID list will re-appear after you program the last block.
  Note: If you select size code S-12, S-13, or S-14, these restrictions apply:
  S-12 can only be assigned to Blocks 0, 2, 4 or 6.
  S-13 can only be assigned to Blocks 0 and 4.
  S-14 can only be assigned to Block 0.
  Since these size codes require multiple blocks, you will be prompted for the next available block. For example, if you assign Block 0 as S-12, the scanner prompts you for block 2, the next block available, instead of block 1. If you assign Block 0 as S-14, you would not see another prompt because S-14 uses all available blocks.
Press MAN to exit programming.

Preset Fleet Maps Contents
In Motorola II systems (no programming the fleet map required), all the blocks have size code, S0, which has a size limitation of 512 radios. In Type I systems, size codes are used in different blocks to denote the maximum number of users in that block. Notice that size code S-12 uses 2 blocks. A Motorola Hybrid system (Type IIi) has 'blocks' of the system that are Type I Fleets/Subfleets and Type II talkgroups. The maps that are Hybrid systems are in bold.

Programming the Offset and Base Frequency  
To properly track Motorola UHF-lo (406-512 MHz) trunked systems, you must program the applicable offset and base frequency for each system. This can be done after you program the trunking frequencies and system. If you don't know the offset and base frequency, I have found an explanation at the Trunked Radio Systems User’s Page. Look for 'Determining Base and Offset Frequencies for the BC245xlt' by John C. There is a similar explanation at Radio Reference.
 
1. In Manual mode select any channel in the bank containing the UHF system by entering the bank number and channel number (Ex: 001) then press MAN to advance to the channel.
2. Press PGM then TRUNK to put the scanner in program and trunk modes. You will see the ID list.
3. Press MODE. MOT: none should appear in the display.
4. Press FUNC then 2. You will see the current settings for the base frequency, offset, and step size. While B in Base is blinking, enter the base frequency then press ENT. Press ENT again to confirm and move down to the Offset setting. Or, if the entry is correct, press ENT to move down.
5. While O in Offset is blinking, enter the offset then press ENT. Press ENT again to confirm and move down to the Step setting. Or, if the entry is correct, press ENT to move down.
6. While S in Step is blinking, press or to select the step then press ENT to confirm and exit. Or, if the entry is correct, press ENT to exit.
Press MAN to exit programming or SCAN to start scanning.

Programming Talk Group IDs Contents
After you program trunked frequencies into a bank, your scanner has 5 scan lists for each bank where you can store IDs. Each list can contain up to 30 IDs, for a total of 150 IDs for each trunk scanning bank. Each of the 5 lists can be turned on or off. If you use all the banks as trunking banks, you can store up to 1500 IDs. If you have more than 150 IDs for a system, or want another list and have an extra bank in your scanner, program the trunked system into 2 banks. You could then have 10 lists (up to 300 IDs) to store and turn on or off for that system.

If you are going to be programming text tags for the IDs, I find it easier to program all the IDs first, then go back and program all the text tags.

To Automatically Store an ID into the first available ID location while trunking, quickly press TRUNK. ID saved briefly appears at the bottom of the display. The ID list (0-4) and ID# (0-29) will briefly be displayed on the bottom line. ID was saved briefly appears at the bottom of the display if the ID has previously been stored (or programmed). If you try to enter more than 150 IDs in a bank, Memory Full! appears.

To Manually Store an ID:
  1. In Manual mode select any channel in the bank containing the ID by entering the bank number and channel number (Ex: 001) then press MAN to advance to the channel.
  2. Press PGM then TRUNK to put the scanner in program and trunk modes. You will see the bank number (0-9), list number (0-4), and the list status (ON or OFF) on the top line.
  3. Press Mode (each time) to select the correct trunking mode if needed.
  4. Press TRUNK (each time) to select one of the 5 ID lists (0-4).
  5. Select the ID# (0-29) by pressing or (or press and hold; faster).
  To Enter an ID:
  To enter a Motorola Type II ID, enter the ID then press ENT to store the ID.
  To enter a Motorola Type I ID, enter the fleet# then press the decimal point to enter a hyphen, then enter the sub-fleet#. Press ENT to store the ID.
  To enter an EDACS ID in decimal (the default) format, enter the ID then press ENT to store the ID. (You don't have to enter leading zeros).
  To enter an EDACS ID in AFS format, press FUNC then 2 to change to AFS format. AFS format will briefly appear on the bottom line. Enter the agency number (xx), use the decimal key for a hyphen, enter the fleet and sub-fleet (xxx), then press ENT to store the ID. See also Switching EDACS Format Display.
  To enter a LTR ID, enter the ID (no hyphens) then press ENT to store the ID.
  Note: If you enter a duplicate ID, Dupl ID and the list number and location of the ID will appear. Press CL to clear or ENT to accept.
  Note: If you enter the ID in the wrong format (ex: an EDACS ID into a Motorola bank), the scanner will beep 3 times and Invalid ID will appear briefly on the bottom line.
  To Text Tag An ID, press TEXT. Move the cursor to the position you want using to move right, or to move left, then skip to Entering Characters.
  To Set the ID Delay for the Bank, Press FUNC then DELAY. Press or to select the delay then press ENT to store the setting. You can't set ID delays per ID like channels. See Changing ID Delay.
  To Lock or Unlock an ID, press L/OUT. LO will appear in the display to the right of the ID# if it is locked out and lo will appear if it is unlocked.
  Press to move to the next ID location and enter the rest of the IDs the same way.
Press MAN to exit programming or SCAN to start scanning.

Changing ID Delay  
You have to set the ID delay for the bank to pause on an ID before scanning resumes. Setting the scan delay for the channel has no effect on an ID. The delay can only be set for the whole bank, not an individual ID. When activated, the ID delay watches the control channel command for the delay time when the signal disappears from the voice channel.
 
1. In Manual mode select any channel of the bank you want to turn a list on or off in by entering the bank number and channel number (Ex: 001) then press MAN to advance to the channel.
2. Press PGM then TRUNK to put the scanner in program and trunk modes. You will see the ID list.
3. Press FUNC then DELAY. Use Up/Down keys to set ID delay appears in the display.
4. Press or to change the delay then press ENT to store the setting.
Press MAN to exit programming.

Clearing IDs  
To clear a single ID:
  1. In Manual mode select any channel of the bank that has the ID you want to clear by entering the bank number and channel number (Ex: 001) then press MAN to advance to the channel.
  2. Press PGM the TRUNK. You will see the bank number (0-9), list number (0-4), and the list status (ON or OFF) on the top line.
  3. Press TRUNK (each time) to select the list (0-4). Select the ID# (0-29) by pressing or (or press and hold; faster).
  4. Press FUNC then CL. Press MAN to exit programming or SCAN to start scanning.
To clear all IDs in a bank:
  1. In Manual mode select any channel of the bank you want clear the IDs in by entering the bank number and channel number (Ex: 001) then press MAN to advance to the channel.
  2. Press PGM the TRUNK. You will see the bank number (0-9), list number (0-4), and the list status (ON or OFF) on the top line.
  3. Press FUNC then 6. Clear entire list ? Press 1 to clear all, any other key aborts appears. Press 1 and Please wait (if there are a lot of IDs) then List cleared will appear. Then the ID list will re-appear. Press MAN to exit programming or SCAN to start scanning.

Signal Stalker II Contents
Your scanner's Signal Stalker II feature provides a powerful new tool for you to rapidly detect, monitor, and store frequencies from nearby radio transmissions. The Signal Stalker II feature is more sensitive than portable frequency counters and will detect transmissions at a greater distance. Signal Stalker II functions by rapidly sweeping through the RF spectrum in 1 MHz segments. If RF signal energy is detected in a 1 MHz segment, Signal Stalker II will sweep through the 1MHz segment in finer steps until the source of the RF signal energy is found. The Signal Stalker II feature is similar in functionality to portable frequency counters that cost much more than your scanner, but provides many advantages over typical portable frequency counters. For example: The Signal Stalker II allows you to sweep the entire range of your scanner's design frequencies, or you can specify just those frequency ranges that you wish to sweep.

The Signal Stalker II feature can be set to watch for activity on all band frequencies or Police/Fire frequencies only. You can turn on/off frequency sub-bands (groups). You can activate the
Attenuator and/or turn the Delay on also. You can lock out 150 frequencies while searching all bands and 50 frequencies while searching Police/Fire frequencies.

Special Signal Stalker

You can also change the Normal Signal Stalker II operation to the Special Signal Stalker II operation. In the Special Stalker operation, the frequency range is still divided by 1 MHz segments. But, if you lockout 5 frequencies within a 1 MHz segment, the scanner will skip that entire segment in subsequent sweeps.

Certain segments of the spectrum are used by high power transmitters, such as paging transmitters. You can press L/OUT when the Signal Stalker II stops on these undesired transmissions to prevent the Signal Stalker II from stopping on them in future sweeps, however, the Signal Stalker II will still see their signal energy when sweeping through the 1 MHz segment. This will cause the Signal Stalker II to execute another fine step search of the 1 MHz segment. If you have locked out the undesired transmissions, the Signal Stalker II will not stop on them again but the overall sweep performance of the Signal Stalker II will be slowed accordingly.
  Note: Priority mode is not available while using Signal Stalker II.
 
Signal Stalker searches in 2 modes:
All bands and just Police/Fire bands.

Changing Receive Modes  
The scanner is preset to the most common AM or FM receive mode for each frequency range. The preset mode is correct in most cases. However, some amateur radio transmissions and trunked systems do not operate in the preset mode. If you try to listen to a transmission when the scanner is not set to the correct receive mode, the transmission might sound weak or distorted. See also Understanding CTCSS/DCS.
 
To change the Receive Mode of a channel, select the channel in manual mode by entering the bank number and channel number (Ex: 001) then press MAN to advance to the channel. Press MODE until the desired mode is found.
  Note: You cannot change the receive mode of a non-trunked channel to MO, ED or LT.
Or, if the scanner is scanning and stops on an active channel, quickly press MODE to change the mode.

Using the Attenuator Contents
To reduce interference or noise caused by strong signals, you can reduce the scanner's sensitivity to these signals. There are two attenuator modes in your scanner. One is normal attenuator mode in which you set the attenuator for each channel (and channels in search SR0-2), each search group (in search banks SR3 and SR5), each search band (SR4 and SR6), or a Tune search. The other is global mode in which applies global attenuation (on or off) to every channel or search regardless of the channel or search attenuation setting.
 
To turn the Attenuator on or off for a single channel while scanning, quickly press ATT while the channel is displayed or select the channel in manual mode by entering the bank number and channel number (Ex: 001) then press MAN to advance to the channel. Press ATT. att turns to ATT in the display when the channel is attenuated.
To turn the Attenuator on or off for Search, press ATT during the search. att turns to ATT in the display when the search is attenuated.
To toggle the Global Attenuator Mode on or off, while searching or scanning, press FUNC then ATT.
To toggle Global Attenuation on or Global Attenuation off, Press ATT while Global Attenuator Mode is active.

Priority Scanning  
You can program one additional conventional frequency, a stored conventional channel, or a weather channel as a priority channel. The Priority feature lets you scan through the channels and still not miss important or interesting calls on a specific frequency. When a channel is selected as the priority channel and priority is turned on, the scanner checks that channel or frequency every 2 seconds, and stays on the channel if there is activity until the activity stops even if the bank for the channel is turned off. The priority feature also works in Search and Manual modes.

The Priority feature does not work properly while trunking an EDACS or Motorola system. (It may seem to work at first but will jump off IDs when the feature checks the priority channel while receiving certain trunked transmissions, especially EDACS, if you can tolerate that. Or, it will not check the priority channel at all during some trunked transmissions).

To Program a channel as the priority channel in manual mode, enter the bank number and channel number then press MAN to advance to the channel. Press FUNC then PRI. You will see Priority Channel blink twice on the bottom line.
  Note: You cannot program a channel which has a receive mode of MO or ED as the priority channel.
To Program a channel when the scanner is scanning and stops on an active channel, quickly press FUNC then PRI before it continues scanning again. You will see Priority Channel blink twice on the bottom line.
To Program a frequency as the priority channel, in manual mode, press PGM then PRI. Enter the frequency you want to use as the priority channel then press ENT.
To Program a Weather Channel as the priority channel, press WX. Select the weather channel you want to use as the priority channel then press FUNC and PRI. You will see Priority Channel blink twice on the bottom line. Press MAN or SCAN to exit. If you program a weather channel as the priority channel, the scanner goes to the priority channel only when the scanner detects the weather alert tone. See Receiving SAME Weather Alerts.
To turn on the Priority Feature, press PRI. When the priority channel is active, Pch will appear on the top line to the left of the channel or frequency.
  PRIon appears in the top line if a AM or FM channel is programmed as the priority channel.
  PRIct appears in the top line if a channel in CT mode is programmed as the priority channel.
  PRIdc appears in the top line if a channel in DC mode is programmed as the priority channel.
  PRIwx appears in the top line if a weather channel is programmed as the priority channel.
To turn off the Priority Feature, press PRI.

Locking/Unlocking Channels  
You can keep the scanner scanning by locking out channels that have a continuous transmission (such as a weather channel).
 
To Lock or Unlock a channel, select the channel by entering the bank number and channel number (Ex: 001) then press MANUAL to advance to the channel. Press L/OUT. lo changes to LO in the display if the channel is locked out.
To Lock out a Channel if the scanner is scanning and stops on the channel, quickly press L/OUT before it continues scanning again. The scanner will lock out the channel and automatically resume scanning.
To View all locked out channels, in manual or program mode, press FUNC then L/OUT (each time) to step through the locked out channels. Press L/OUT to unlock a channel. If there are no locked out channels, then the scanner will just beep.
  Note: You can still monitor locked out channels in manual and program modes.

Scanning and Trunking Banks Contents
You can trunktrack a selected bank only after you have programmed the frequencies and trunking system for that bank. See Programming Trunked Systems.
 
Your scanner automatically mutes the audio during trunking when it decodes control channel data. However, it is recommended that (in manual mode) you turn SQ clockwise and leave it set to a point just after the hissing sound stops. This lets the scanner quickly acquire the data channel.
 
If you have a trunk system programmed (correctly) into a bank with conventional frequencies, the scanner will scan and trunktrack. You can't make it only scan or only trunktrack the bank (unless you lock out those frequencies you don't want scanned or trunktracked).
 
Press SCAN to start scanning.
Select any combination of banks to scan by pushing the number keys that correspond to the banks. Numbers appear at the top of the display showing the currently selected banks. The cursor blinks on the bank number when the scanner scans the channels in that bank. If the scanner finds an active channel or ID, it stops on it. When the transmission ends, the scanner resumes scanning. If it is a long transmission, (such as a Ham rag chewing) and you want to move on, press SCAN again to resume scanning. The scanner won't scan channels that are locked out or have 0 as the frequency.
  If the scanner picks up an unwanted partial frequency, turn SQ clockwise to decrease the scanner's sensitivity and mute the scanner so it will continue scanning.
  To listen to a weak or distant frequency, turn SQ counter-clockwise to increase the scanner's sensitivity.
  To change the scan direction, press or .
  To turn banks on or off, press the number key, 0-9 that corresponds to the bank you want to turn on or off. You cannot turn off all banks. One bank must always be active.

  To turn ID lists on or off (in closed mode only), quickly press FUNC then TRUNK while an ID is displayed. 'ID Banks:' and the lists that are turned on will appear as numbers on the 3rd line when transmissions are received. The cursor will blink on the list number that has the receiving ID. If the list is turned off a . (dot) will replace the number. Quickly press FUNC then the list number while receiving to turn the list on or off. (Yeah, right, real simple). Quickly press FUNC then TRUNK while an ID is displayed to get rid of the 'ID Banks:' selection line.
Or, See Turning ID Lists Off and On to do it in Manual mode before scanning.
To exit trunking and scanning, press MAN.
 
While trunking, you may not know which agency, fleet, or talk group the talk group IDs are assigned to until you listen a while. You can determine the type of agency you are listening to after a short while by matching the IDs with the transmission you hear. You can then program them into ID lists. See Programming Talk Group IDs. Determining the service associated with a talk group ID might take awhile but finding IDs is half the fun.

Changing Open and Closed Modes Contents
You can set each bank to open or closed mode.
 
In open mode the scanner will receive:
(1)
all channels in AM, FM, CT and DC modes that are not locked out.
(2) all IDs in MO and ED modes, even if they are locked out in the ID list.
In closed mode the scanner will receive:
(1)
all channels in AM, FM, CT and DC modes, that are not locked out.
(2) only IDs in MO, ED, and LT modes that are programmed into the ID list, and not locked out in the ID list

Weather Radio  

Listening to the Weather Band Contents
To hear your local forecast and regional weather information, press WX. The scanner will scan through the weather channels and stop within a few seconds. If it is a weak signal, press WX again to find a stronger channel.
Press MAN or SCAN to exit.

Receiving SAME Weather Alerts  
The weather service precedes each weather alert with a digitally-encoded SAME (Specific Area Message Encoding) signal, then a 1050 Hz tone. You can set the scanner to decode and display the SAME message when an alert is broadcast. Then if you are monitoring a weather channel with a digitally-encoded SAME signal when an alert is broadcast, the scanner will show the type of alert being broadcast such as Warning, Watch, Statement, or Test Message. The scanner will also sound alternating alert tones and display Weather ALERT when the scanner receives a 1050 Hz tone. The scanner does not display the actual messages. It uses only the alert portion of the SAME signal (Warning, Watch, Statement, or Test Message). To scan and receive alerts, set the weather channel as the priority channel.

For the purpose of broadcasting weather information, the NWS has divided the United States into regions by state and county (or parish, where applicable) then assigned a 6-digit FIPS code to identify each county or parish. For example, the code for Tarrant County, Texas, is 048439. The first digit in a FIPS code identifies the county subdivision, the next two digits identify the state, and the last three digits identify the county or parish. Most FIPS codes begin with 0, which means the code represents an entire county. The NWS, however, plans to eventually subdivide some large counties. When that happens, each subdivision will be assigned a digit from 1-9, resulting in codes such as 148439, 248439, and so on.

To obtain the FIPS code for the location where you installed your scanner call the NWS toll free at 1-888-697-7263 (follow the instructions you hear) or see
FIP codes for the United States and its Possessions.

FIPS codes are in the format nSSCCC:

n: A special subcounty designator. For an entire county, use 0.
SS: The state code.
CCC: The county code.
 
To turn on the weather alert, while listening to a weather channel, press FUNC then WX. FIPS: ALL Codes and SAME Standby appear. All codes will be received if none are programmed(?). The scanners sound will mute and wait for a tone. When the scanner receives an alert, it will beep for 5 minutes or until you press any key (except lit light/key symbol). If, after 5 minutes no key has been pressed, the scanner will beep every ten seconds. If the scanner receives a new alert after 5 minutes, the scanner will again beep for 5 minutes or until you press any key. Pressing any key will ready the scanner for another tone.
To test the alert tones, with the alert on, press and hold WX. The scanner will cycle through the different beeps every 3 seconds showing the corresponding alerts on the display. Press any key to cancel.
To turn off the weather alert, press FUNC then WX. DIG WX STBY and CANCEL: F+WX disappear. The scanner will resume receiving the weather channel.
To program a weather channel as the priority channel, press WX. Select the weather channel you want to use as the priority channel then press FUNC and PRI. If you program a weather channel as the priority channel, the scanner stays in the priority channel only when the scanner detects the weather alert tone. In this mode all alerts are received. FIPS settings are ignored.
To program specific FIP codes, press WX to put the scanner in weather search mode.
  Press FUNC then PGM and you will see FIPCode Setting.
  Press or to select the location number (0-9).
  Enter the FIP code and press ENT. Press L/OUT to lockout the code if you wish.
To clear a code press FUNC then CL (Clear).
  If you want to tag the code press TEXT. See Entering Characters.
  Press or to select the next code location to program more codes.
  Press WX to exit.
To review stored FIP codes, press WX then the location number (0-9).
Press MAN or SCAN to exit.

Skywarn Programming  
Many areas of the country have amateur radio repeaters that have been designated as Skywarn repeaters. During times of severe weather, these repeaters are used to relay reports of severe weather directly to meteorologists at a local National Weather Service (NWS) forecast office. Using the Skywarn feature in your scanner, you can easily jump to one of three Skywarn repeater frequencies and monitor these reports, in many cases hearing about severe weather in your area instantly as it occurs. This function lets you quickly move to the skywarn channels (channels 997 through 999) from any mode except SAME standby mode. To see a partial list of state Skywarn frequencies go to the Scanning Reference weather site here.
 
To use the Skywarn feature, program up to 3 Skywarn frequencies in channels 997-999 (use FM mode). See Programming Conventional Channels.
  Press and hold WX for about 1 second. You will see Skywarn-1 on the bottom line.
  Pressing or will search through the 3 Skywarn channels.
Press MAN or SCAN to exit.

Your scanner features a power save circuit that is automatically activated after about 30 seconds if you have manually select a channel. The power save mode works by allowing the receiver to 'sleep' briefly while waiting for a call on the selected channel and will also turn the backlight off. The power save circuit is disabled when the scanner is tuned to a channel in program mode, scanning, or searching.

Related Links/Info Contents
Using the Repeater Finder Tool
To determine the correct Home Repeater programming, enter the system channels of an LTR system in any order. Be sure to program the mode for each LTR channel to LT. Listen to each channel one at a time in manual mode and watch for the decoded LTR data at the bottom of the scanner's display. When an LTR transmission occurs, you should see the LTR talkgroup information on the bottom line of the display, and a number preceded by 'R' in the bottom right hand corner (i.e., R12). The 'R' number is the Home Repeater number that the current transmission is occurring on. To correctly program this Home Repeater number into your scanner, be sure that the channel number in the bank is equal to the number that is displayed after the 'R'. For example, if you see R12 displayed on a particular LTR frequency, that frequency needs to be programmed into Channel 12 of the current bank in order to track the LTR system activity properly.
 
How to view these pages in your browsers
I have formatted these pages so that you can view them with any monitor, in any browser (Foxfire, Opera, I.E., or Netscape), at any zoom level, and in any screen area size (ex: 600x800)-small or large fonts. So if the print is too small, go to the 'view' menu in your browser and adjust it to a bigger level (or smaller if you want to see more on the screen).
