Overview Contents
As you have found out by now, this is a whole different animal as far as scanners go. I have tried to write my manual to follow the menu sequences as close as possible so you can find things a little easier in the radio.
 
Again, the manual is like trying to set a watch made in China. My biggest gripe is that it doesn't follow the menus of the radio. So, I have written this manual for myself so I can actually use the scanner and will share it with you.
 
It does have some cool new features: Close Call, Dynamic Memory, an adjustable 'Hold (scan) time' for each system, Search and Store (actually an old feature brought back), and the ability to hold about 1600 (tagged) channels. You can store up to 200 different systems (if there is enough memory). The 'quick keys' allow you to scan any combination of systems. There doesn't seem to be a limit to how many priority channels you can program. It has a very bright display and the sound quality is great for a 'mini' scanner. When set to tone search it will search for CTCSS and DCS tones, not just one or the other. You can program alerts for selected channels and Close Call hits with different alert sounds and adjustable volumes. The Race Track Operation is a plus for race fans but the preprogrammed races are probably outdated. The Close Call and Weather Priority features will run in the background while scanning or searching. And, of course, computer upload/download/clone and control. An AC adapter, computer cable, and batteries come with the scanner. The firmware is supposed to be upgradeable.

I've been able to program over 200 cars (Butel software only sees 100) and program at least 150 freqs for a driver. One trick would be to program a conventional system as a race system, use the 'driver' for the alpha tag because race systems show the frequency in the display. Too bad you can only scan 1 race system at a time.
 
Now the annoying stuff. Dynamic Memory has it's drawbacks because you have to build everything first then program it. Press and hold for 2 seconds to turn the scanner on?? There is too much stuff that is only in the menu; you should be able to access more features (like unlocking a channel) with just the keypad. Alpha tagging is best left to the software. The channels aren't numbered so they can be hard to find if you have a lot of them in a group. There is no 'per channel' delay; you must set the delay for the whole system (all groups, all channels).

There are better antennas out there to use than the one that comes with the scanner.
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 800+ 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.

An overview of the features can also be viewed at my
Conventional Radio Comparison Chart page.
 
It is also recommended that you download and install the latest firmware upgrade for the scanner if you don't have it. See checking Firmware Version. If you have a big database of channels to program you will definitely need the programming software.
 
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.

Main Features Contents
Close Call RF Capture Technology - you can set the scanner so it detects and provides information about nearby radio transmissions.
Dynamically Allocated Channel Memory - organized into 'Systems', 'Groups' (within systems), and channels (within groups). As many channels as memory allows. Typically about 2500 (1600 with tags).
Race Track Operation - you can set the scanner to scan races using a frequency list or preprogrammed into the scanner. You can scan by car number and driver name, assign the car to a quick key, and set the scanner so it sounds an alert when the car you are scanning transmits.
Preprogrammed Races - your scanner is preprogrammed with major races.
10 Service Searches (Air only w/USC230) - frequencies are preset in separate public safety, news, amateur radio, marine, railroad, air, CB radio, FRS/GMRS, racing, and special searches, to make it easy to find specific transmissions.
Channel Alerts - you can set the scanner so it alerts you when there is activity on any channel you specify.
Quick Keys - you can set the scanner so you can select systems by pressing a single key. This makes it easy to listen to or quickly turn off those systems or groups you don't want to scan.
10 Custom Searches - lets you program up to 10 custom search ranges.
Quick Search - lets you search from the currently-tuned frequency if you are searching a conventional system.
Pager Screen (not w/USC230) - Sets the scanner so it ignores Close Call or search hits on known pager frequencies.
Frequency Search and Store - scanner can be set to automatically store all active frequencies from a service or limit search in a conventional system you select.
Priority/Priority Plus Scan - priority channels let you keep track of activity on your most important channel's) while monitoring other channels for transmissions and you can scan just the priority channels.
Adjustable Channel/Frequency Step - allows you to set the step (5, 6.25, 7.5, 8.33[USC230 only],10, 12.5,15, 20, 25, 50 or 100 kHz) of each conventional channel or search band or auto select mode.
CTCSS/DCS Search - lets you search for CTCSS and DCS tones when it finds an active frequency in search and close call modes.
Adjustable Hold (Scan) Time per System - allows you to adjust the length of time spent scanning each system.
CTCSS and DCS Tone Decode - decodes and displays Continuous Tone Code Squelch System tones being transmitted and plays Digital Coded Squelch being received. Also, a tone code only receive option (per channel).
Text Tagging - you can name each system, group, channel, custom search range, and SAME group, using up to 16 characters per name.
Adjustable Scan/Search Delay - from 1 to 5 seconds or off (per channel or frequency).
Attenuator - you can set the scanner's attenuator to reduce the input strength of strong signals by about 18 dB per channel, search band, or close call band.
Repeater Reverse - tells the scanner to try to switch to the repeater if an input frequency is found.
Data Skip - allows your scanner to skip unwanted data transmissions and reduces birdies.
Duplicate Frequency Alert - alerts you if you try to enter a duplicate name or frequency already stored in the scanner.
SAME Weather Alert (not w/USC230) - (with programmable FIP codes) lets your scanner alert you when a SAME weather alert is transmitted on a NOAA weather channel. The scanner also displays the alert type.
Search Lockouts - you can lock out up to 200 frequencies in search or close call search.
PC Control/Clone - you can transfer data to and from your scanner or another scanner and your personal computer, and control the scanner using a computer.
Low Battery Alert - the scanner alerts you if the batteries need to be recharged or replaced.
Battery Saver - you can set the scanner so it reduces the amount of power it needs if there are no transmissions.
Key Lock - you can deactivate the scanner's keys to help prevent accidentally changing the scanner's programming.

Scanning Terminology Contents
Channel- a programmed frequency location.
Scanning- the process of stepping through conventional channels in groups, which are in programmed 'systems'.
Searching- the process of searching for active frequencies in quick search, service, custom search, Close Call search, auto search and store, or close call auto store.
Function Mode- the mode the radio is in when it's waiting for another key press or scroll.
Hold Mode- used for monitoring a single channel, frequency, or Close Call Hit.
Menu Mode- used for programming frequencies, systems, groups, and other 'system' settings.

Understanding Dynamic Memory Contents
The scanner's memory is organized in an architecture called Dynamic Allocated Channel memory. This type of memory is organized differently and more efficiently than the bank/channel architecture used by traditional scanners. Dynamic Allocated design matches how radio systems actually work much more closely and make it easier to determine how much memory you have used and how much you have left. No memory space is wasted.
 
Instead of being organized into separate banks and channels, the scanner's memory is contained in a pool. You build the systems and groups then use as much memory as you need in the pool to store frequencies and alpha tags. With all previous scanners, you selected banks to scan that had channels stored in them. With this scanner, you select 'Systems' to scan that have channel 'Groups' stored within the 'Systems'.

Within the Racing 'Systems', you can store 'Cars'. Cars are like 'Groups' but you can store more than 20 of them (Butel software only sees up to 99). You can store as many as 200(?) frequencies for each Car (if you have enough memory). One trick would be to program a conventional system as a race system and use the 'driver' for the alpha tag because then you can see the frequency AND the alpha-tag in the display. It is a little more work to program even with the software, uploads to the scanner slower, and takes up more memory but remember, you can only scan 1 race system at a time.

You can store as many as 200 'Systems' and you can have as many as 20 groups per 'System' with up to 200 frequencies in each 'Group' (if you have enough memory). The manual says up to about 2500 channels but with alpha tags you get about 1600.

Understanding Quick Keys
'Quick Keys' are used to turn systems and groups on and off (enable or disable for scanning). This is not the same as locking out or unlocking systems or groups (which you can also do). They are just the number keys on the scanner but once programmed to systems or groups they become the 'Quick Key' for the systems or groups.

There are 10 'System Quick Keys' (0-9) and 10 and 'Group Quick Keys' (0-9).

'Quick Keys' are used to turn systems, channel groups, and cars on and off. This is not the same as locking out or unlocking systems/groups/cars (which you can also do). They are just the number keys on the scanner but once assigned to systems/groups/cars they become the 'Quick Key's. You can program one or more system/group/car to any quick key or, program one or more system/group/car with no quick key. Any system, Close Call system, group, car, or 'Quick Save' system/group not assigned to a
quick key (and/or not locked out) will be scanned.

My advice is to assign everything to quick keys so you don't have to remember what to turn off/on or what to unlock/lockout. There are no indicators in the display showing systems/groups/cars with no quick key so you won't know if they are being scanned unless you see (or don't see) them scroll by in the display.

'Race' systems don't have system quick keys. You can only scan one race system at a time (with any other conventional/trunked systems) by unlocking a race system which will then lockout any other race system that is already unlocked. They do have car quick keys that are used just like group quick keys.

Conventional Simplex and Repeater Systems Contents
Simplex systems use a single frequency for both transmit and receive. Most radios using this type of operation are limited to line-of-sight operation. This type of radio is frequently used at construction job sites, and with inexpensive consumer radios such as GMRS/FRS radios. The range is typically 1-8 miles, depending upon the terrain and many other factors.
 
Repeater systems use two frequencies: one transmits from the radio to a central repeater; the other transmits from the repeater to other radios in the system. With a repeater based system, the repeater is located on top of a tall building or on a radio tower that provides great visibility to the area of operation. When a user transmits (on an input frequency), the signal is picked up by the repeater and retransmitted (on an output frequency). The user's radios always listen for activity on the output frequency and transmit on the input frequency. Since the repeater is located very high, there is a very large line of sight. Typical repeater systems provide coverage out to about a 25-mile radius from the repeater location.

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.

Turning on the Scanner and Setting the Squelch  
1. Turn Sql fully counterclockwise.
2. Press and hold for about 2 seconds to turn on the scanner, then turn Vol clockwise until you hear a hissing sound.
3. Turn Sql clockwise until the hissing stops.
 
The only thing you will be able to scan right out of the box are the preprogrammed systems in the scanner (quick key 9). You will, however, be able to do a service search, custom search, weather search, search and store, close call search, or close call auto store.

Planning Conventional Systems and Groups Contents
Planning your systems will be very important even if you do have the software. Organizing your quick keys will be the hardest part of the planning. You can assign quick keys and copy and paste most of the freqs, and alpha tags easier with the software.

Unless you live in a real big city, most people can get everything they scan into the scanner. I like to scan by general interest so I set my system quick keys accordingly; 1-Public Safety systems, 2-Air, 3-Military, 4-Federal, etc. Then I will nest my groups (ex: Fire, Police, EMS) within the conventional systems and give them all group quick keys. Unless you always want a group or system on, assign it a quick key; it's easier to turn the quick key off than to lockout or unlock the group or system (IMHO). If you do live in a big city, you might want to get the BCD396T with more channels, quick keys, and digital capabilities because you'll need it eventually.

So, you have to figure out which systems and groups to assign to your quick keys so you can scan them without a table of contents and with some sort of logic you can remember. Use the worksheets below to help you plan your systems and groups.

Alerts You can program your scanner to alert you when, a channel is received, or you receive a Close Call hit. For each alert in the scanner, you can select from 9 different tone patterns, and 15 volume settings.
  Planning Race Systems  
Most people would scan the race system and then conventional systems that compliment the race (officials, scoring, radio, etc.). So, program all the drivers and their frequencies for each race system. Program your conventional systems with groups for officials, scoring, radio, etc. Use the worksheets below to help you plan your systems and groups.

  Worksheets  
I have put together complete worksheets ready to print to help you plan your systems, Close Call, and search etc. settings. Even if you don't fill them out, they are a good check list for programming.

Programming Systems Contents
You have to create systems first, create groups or cars in the systems, create channels in the groups/cars, then program your frequencies into the channels. Or, you can Quickstore freqs. You can store up to 200 systems, up to 20 groups per system or 200+ cars per race system, and up to 200 channels per group. Total channels are limited to about 2500. Channels that have text tags use more memory than those that do not. If you use a text tag for every channel, total channels are about 1600.

One suggestion; assign every group and every system to a quick key. You can assign as many systems you want to a system quick key and as many groups as you want to a group quick key. That way you can just turn systems and groups on and off and not have to worry about locking them out. If you don't assign a system or group to a quick key, you have to lock it out if you don't want to scan it.

worksheets to help you program your systems and groups.

  Note: The quick keys for the system(s) and group(s) containing the priority channel(s) have to be turned on (and groups and systems have to be unlocked) or the scanner will display Priority Scan No Channel.

Scanning Systems Contents
With all previous scanners, you selected banks to scan that had channels stored in them. With this scanner, you select 'System Quick Keys' to scan that have 'Systems' assigned to them. So, now you turn 'System Quick Keys' on and off and 'Group/Car Quick Keys' on and off (within each 'System'). Race systems don't have quick keys and can be only locked or unlocked. Turning quick keys on and off for systems/groups is not the same as locking and unlocking systems/groups. You can still do that separately (if you really want to confuse yourself). See also Understanding Quick Keys.

First, (unlocked) systems to Quick Key 1 are scanned. Then systems that belong to Quick Key 2,,9,0 are scanned in order. Systems with the same quick key are scanned in order of creation. Systems with no quick key are scanned last and in order of creation (including created 'Quick Save' systems). Groups/Cars within the systems are scanned with the same rules. Conventional channels within the groups are scanned in order of creation.

Then the scanner starts all over.

 
Press Scan. The scanner scans a system for the duration you set using the 'system hold time' option. The scanner moves to the next system after the hold time expires, the current transmission ends, and the channel delay expires.
 
Notes: If no systems are programmed, or all systems (or groups in a system) are locked out or turned off, 'Nothing to Scan' appears. Turn on a system quick key or unlock a system to scan. If you turn off all groups in a system you will not be able to turn any back on and also see 'Nothing to Scan'. This is a bug that frustrates everybody. In that case, while in Scan mode, press and hold Func-don't let go. Scroll to the system then press the number of the group quick key(s) you want to enable then let go of Func.

Any system, group, or 'Quick Save' system/group
not assigned to a quick key (and/or not locked out) will be scanned.
 
  To continue scanning (move on to the next channel), press Scan or turn the scroll control.
  To scan the preprogrammed systems that come with the scanner, all systems preprogrammed into the scanner are assigned to quick key 9. While scanning, press 9 to toggle the preprogrammed systems on or off. You will see the number 9 (to the right of 'SYS') in the display when the preprogrammed systems are turned on.
To turn a race system on or off, Press 0/Race. Scroll to the race and press E/Yes.
To turn system quick keys on or off, press the corresponding numbers on the keypad that are assigned to the system(s) you want to listen to. You will see the numbers (to the right of 'SYS') in the display of the system keys that are turned on.
  Note: Any system not assigned to a quick key (and not locked out) will still be scanned.
  To turn a single system (not a system key) on or off, or a system not assigned to a quick key, you have to unlock it or lock it out. Press and hold the Func button. Rotate the scroll control until the system want to lock or unlock appears. Press L/O to lock or unlock the system. Releasing the Func button will return to scanning.
To turn group/car quick keys on or off, while scanning press and hold the Func button-don't let go. Scroll to the system that contains the group/car you want to turn on/off then press the corresponding number key(s) on the keypad. You will see the numbers (to the right of 'GRP') in the display for the group/car keys that are turned on. Releasing the Func button will return to scanning. Or, if you are quick enough, press and hold Func then the corresponding number key(s) on the keypad while the system is being scanned.
  Note: Any group/car not assigned to a quick key (and not locked out) will still be scanned.
  To turn a single group/car (not a group/car key) on or off, or a group/car not assigned to a quick key, you have to unlock it or lock it out. See Locking/Unlocking Group/Cars.

Close Call Menu  
Your scanner's Close Call feature lets you set the scanner so it detects, alerts you to, and displays the frequency of a nearby strong radio transmission. You can set the scanner so the Close Call feature checks for a Close Call hit every 2 seconds in the background while you are scanning or searching or use Close Call only mode. You can also set the frequency band(s) where you want the scanner to look for transmissions. When the scanner detects a Close Call hit, it alerts you according to the Override and Alert settings. You can also set the scanner to Auto Store Close Call hits. The system 'Close Call' is created when you run a Close Call AutoStore. See Search/Close Call Options for more options with Close Call Search. The Close Call feature does not work for frequencies greater than 956 MHz.

(for the USC230) CC DND (Do Not Disturb) - The scanner checks for a Close Call hit every 2 seconds only if the scanner is not currently stopped on a transmission. If the scanner is on a transmission the scanner waits until the signal ends to perform a Close Call check. This prevents breaks in audio during Close Call checks. CC PRI - Close Call works even if there is a transmission.

The Close Call feature works well for locating the source of strong local transmissions such as mobile and handheld two-way radios in areas with no other strong transmission sources. Several factors affect Close Call performance. Performance is increased with higher transmit power, receive antenna tuned to the target band, and a low background RF level. Other than the antenna, you have no control over these factors, but they explain why performance might vary by both location and time. The Close Call feature works better with some types of transmissions than others. It might not correctly display frequency information for transmitters using a highly directional antenna (such as an amateur radio beam antenna) or if there are many transmitters operating at the same time in the same area.

Programming SAME Groups  
SAME (Specific Area Messaging System) is a system developed by the National Weather Service to reduce the number of alerts received by consumers by allowing them to hear alerts only for the county(ies) they are interested in. Each alert contains information about the type and severity of the alert, as well as the specific geographic locations affected by the alert. In addition, certain special regions and wildcard settings can be assigned. Your scanner can receive all SAME alert signals broadcast within about a 50-mile radius of where you installed it.

To receive SAME alerts and broadcasts about weather occurring only in particular counties within that area, you can program up to 5 (tagable) groups of 8 FIPS codes (40 codes) into the scanners memory. This lets you avoid hearing an alert that applies to an area within a 50-mile radius but not necessarily to your county or parish.

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 sub county designator. For an entire county, use 0.
SS: The state code.
CCC: The county code.
  To program SAME groups, press Hold to hold on any channel.
Press and hold Func then 2/(WX).
At 'WX Operation' scroll to 'Program SAME' and press E/Yes.
At 'Select SAME' scroll to the SAME group (1-5) and press E/Yes.

  'SAME 1-5' The scanner alerts and displays information about the weather alert when it receives a weather alert signal that includes any FIPS code you have programmed into the specified SAME group.
  'All FIPS' The scanner alerts and displays information about the weather alert when it receives any FIPS code.
  The scanner will mute and scan the weather channels. When it detects a 1050 Hz tone that accompanies all weather alerts it sounds a tone, displays information about the weather alert, and turns on the audio so you can hear the weather broadcast. This is especially useful when your area is expecting severe weather conditions late at night.

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).

Firmware Upgrades
For the latest version for the SC230 you now have to register your scanner at Uniden's site to download the update. You also have to download and install an 'updater' program (BC_VUP_v2.0.07.exe) first to install the upgrade. And, you should also download and read the release notes that have the instructions on how to apply the upgrade. As of this writing, there are no updates available for the USC230.

Menu Outline Contents
The scanner's menu lets you select options that let you set up and use the scanner. To use the menu, press the Menu button on the left side of the scanner. In most cases, the current menu position appears on the upper line of the menu. Menu items and a place to input information appear on the lower line of the menu. To select a menu item, turn the scroll control on top of the scanner clockwise or counterclockwise. When the menu item you want to select appears, press E/Yes or press the scroll control down to select it. To back up a level or return to the previous level, press Menu. To exit the menu mode, press Scan. Below I have mapped out the menu.

Note: This is the menu for the 2.01 firmware version.
