Important Notice
This scanning radio has been manufactured so that it will not tune to the radio frequencies assigned by the FCC for cellular telephone usage. The Electronic Communications Privacy Act of 1986, as amended, makes it a federal crime to intentionally intercept cellular or cordless telephone transmissions or to market this radio when altered to receive them.
The installation, possession, or use of this scanning radio in a motor vehicle may be prohibited, regulated, or require a permit in certain states, cities, and/or local jurisdictions. Your local law enforcement officials should be able to provide you with information regarding the laws in your community.
Changes or modifications to this product not expressly approved by Uniden, or operation of this product in any way other than as detailed by this Operating Guide, could void your authority to operate this product.

that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until another transmission is received.

Conventional scanning is a simple concept. You enter a radio frequency in your scanner’s memory which is used by someone you want to monitor. For example, the police in your area may broadcast on 460.500 MHz , the fire department on 154.445 MHz, the highway department on
37.900 MHz, etc. So when your scanner stops on a frequency, you usually know who it is, and more importantly, you can stop on a channel and listen to an entire conversation. This type of scanning is easy and fun.
As the demand for public communications has increased, many public radio users don’t have enough frequencies to meet their needs, and this has created a serious problem. Trunking radio systems solve this problem.
5
In a trunked radio system, which contains up to 29 different frequencies, radio users are divided into groups, often called talk groups, and these talk groups are assigned specific IDs. When someone in a talk group uses their radio, a brief bust of data is broadcast before each transmission. The trunking system computer uses this data to temporarily assign each radio in a talk group to an available frequency. If the group using a frequency stops broadcasting or pauses between replies for a few seconds, they are removed from the frequency so another talk group can use it.
Sharing of the available public service frequencies, or trunking, allows cities, counties, or other agencies to accommodate hundreds of users with relatively few frequencies. On the other hand, following a conversation on a trunked system is difficult, if not impossible, because when there’s a short break during the conversation you’re monitoring, it’s possible that the talk group will be assigned to a completely different frequency in the trunked system. This type of scanning is difficult and frustrating.
TrunkTracker™
BC 235XLT
changes this! Not only does your new
scan channels like a conventional scanner, it actually follows the users of a trunked radio system. Once you know a talk group’s ID, you won’t miss any of the action.
If you’re a new scanner enthusiast, you may want to read the first part of this manual and use your scanner in conventional mode before you begin trunk tracking. Understanding scanning fundamentals and its terminology will make trunk tracking much easier. But if you’re already a sophisticated scanner operator, you may want to go to

Feature Highlights
Trunk Tracking – Follow 800 MHz trunked public safety and public service systems just as if conventional two-way communications were used.
300 Channels – Program one frequency into each channel. You must have at least one channel programmed to use the Scan mode.
12 Bands, 10 Banks – Includes 12 bands, with Aircraft and 800 MHz. 10 banks with 30 channels each are useful for storing similar frequencies to maintain faster scanning cycles or storing all the frequencies of a trunked system.
29 MHz-956 MHz – Indicates the range of frequencies that can be searched within the bands of your scanner.
Note: The frequency coverage is not continuous and excludes the cellular band.
10 Priority Channels – You can assign one priority channel in each bank. Assigning a priority channel allows you to keep track of activity on your most important channel(s) while monitoring other channels for transmissions.
Preprogrammed Service (SVC) Search – Allows you to toggle through preprogrammed police, fire/emergency, aircraft, marine, and weather frequencies.
Unique Data Skip – Allows your scanner to skip unwanted data transmissions and reduces birdies.
Memory Backup – If the battery completely discharges or if power is disconnected, the frequencies programmed in your scanner are retained in memory.
Manual Channel Access – Go directly to any channel.
LCD Back Light – An LCD light remains on for 15 seconds when
Battery Save – In manual mode, your scanner automatically reduces its power requirements to extend the battery’s charge.

Programming Tips
Do not program a weather frequency into one of the channels, since weather channels transmit continuously.
Use Group similar frequencies into adjacent channels.
For example, program police frequencies in channels 1 through 10 and fire/emergency into channels 11 through 20, and so on.
Put the frequency that you listen to the most or the most important frequency into a Priority channel.
To quickly program a series of channels, start with the lowest number channel.
For example, when you are programming five new frequencies into Channels 4 through 8, start with Channel 4. After you finish programming a channel, press channel.

Your scanner defaults to monitor Type II systems; however, you can change this if the system in your area is different. (The types of systems are discussed below.)
Your scanner cannot track an 800 MHz trunked system and scan frequencies in conventional mode at the same time.
The frequencies for many of the 800 MHz public safety systems are listed in the

are
Types of Trunking Systems
Trunking systems divide a few frequencies among many different users, but the way that each system does this is slightly different. There are really two basic types which are important when using your TrunkTracker™ scanner. These are usually referred to as Type I and Type II systems.
One important distinction between these two systems is the amount of data transmitted by each radio when its push-to-talk button (PTT) is pressed. Every radio in a trunked system is assigned a unique ID so the central site computer can identify it when it’s used. Both Type I and Type II systems place radios (or radio users) into groups, called talk groups, and these talk groups are also assigned unique IDs. Some radios have access to only one talk group, while others have access to many talk groups. Which talk group(s) each radio can access is called the radio’s affiliation(s).
35
In a Type II system, when someone uses their radio, only the radio ID is transmitted when PTT is pressed, whereas in a Type I system the radio ID and its current affiliation are both transmitted when PTT is pressed.
Why the difference? Type II systems are slightly more advanced because the central computer maintains a database which is used to determine each radio’s affiliation(s). Changes to a Type II system are easier than Type I because the system manager only need update the database instead of reprogramming individual radios.
Another difference between the systems is that Type I systems are arranged in a Fleet-Subfleet hierarchy. For example, it’s possible for a city using a Type I system to designate 4 Fleets, each with 8 Subfleets. Their fleets might be the Police Department, the Fire Department, Utilities, and Administration. The Police may decide to further divide their fleet into subfleets such as Dispatch, Tactical Operations, Detectives, North, South, East and West Side Patrols, and Supervisors. All the available police radios would then be assigned to one of the police subfleets. Determining the exact Fleet-Subfleet hierarchy for a particular area is referred to as Fleet Map Programming.
The disadvantage of a Type I system is that when PTT is pressed, the brief bust of data must contain the radio’s ID and its Fleet and Subfleet. This is three times the amount of data a Type II system radio sends, and as a result Type I systems usually accommodate fewer users than Type II systems.
Even though there are many Type II systems, Type I systems are still in use. There are also Hybrid systems which are a combination of both Type I and Type II. Your scanner defaults to monitor Type II systems, but it’s possible to select a Preprogrammed Fleet Map or create a Custom Fleet Map for your area.
36
Setting the Squelch
Since Squelch is automatically adjusted in trunking mode, it isn’t necessary to manually adjust the squelch control while trunk tracking. However, the squelch setting you select before you begin trunk tracking can affect how fast your scanner acquires the data channel, and, in some instances, the squelch setting can prevent your scanner from acquiring the data channel at all.

Note: You can change this recommended setting, if necessary, to provide better performance in your area.

Programming Trunking Frequencies
Before you start programming your scanner to track a trunked system, consider the following:
You can only program one trunking system in each bank of your scanner.
Trunking frequencies must be entered while in the Trunking Programming mode.
If you’re in the Trunking Programming mode, you cannot select channels in other banks.
For example, if you are programming Bank 4, you can only select channels 91-120 with the keys.

ID Lockout
Like conventional scanning, it’s possible to lockout unwanted traffic.

Also some departments scramble or encrypt their communications, and you may want to lock out these unintelligible broadcasts.
To lockout an ID, press displays.
The ID is locked out, and the next active ID displays. You can lockout up to 100 IDs.

■
The indicator which remains on, even if when there is no traffic, represents the frequency being used as the data channel.

If an indicator turns on and you don’t hear a conversation, then the channel is probably being used for a telephone interconnect call or a private call. These calls are not monitored by your scanner.
■
The indicator which flashes when an ID displays represents the frequency being used by the talk group.

If you’re holding on an ID which isn’t active, the activity indicators will turn on and off as other groups use the system.
Note: If more than 20 channels are stored in a bank, then the indicators represent multiple channels. For example, if 29 channels are programmed, the first 9 activity indicators each represent two channels.
45
Scan Lists
Each bank of your bank or it can be a conventional scanning bank. When you designate a bank as a trunking bank, your scanner sets up 5 Scan Lists, which are simply lists used to store your favorite IDs. Each list can contain up to 10 IDs, so you can store a total of 50 IDs for each trunk tracking bank (500 if you use all banks as trunking banks!).
Scan Lists help you organize the trunking system users into categories. For example, you might use List 1 for police IDs, List 2 for fire department IDs, List 3 for emergency medical service IDs, etc. Once IDs are stored in lists, you can scan them like you scan conventional frequencies. You can program your scan lists either manually or during trunking search mode.

Fleet Map Programming
If you have programmed a trunk tracking bank and select

R
the
BC 235XLT
will appear as numbers. However, if you notice a mix of odd and even user IDs, for example 6477, 2560, 6481, 6144, 1167, etc., then you are probably monitoring either a Type I or Hybrid system. See on page 35.
You may also notice that you’re missing responses when you hold on an active ID. Unlike Type II systems, Type I/IIi systems require a Fleet Map that sets specific Fleet-Subfleet parameters. It’s easy to select a Fleet Map for your scanner; what isn’t always easy is selecting or programming a map that matches your particular area.
There are 16 preset Fleet Maps listed in the appendix that you can choose, and these are usually a good place to start when setting up a Type I/IIi trunk tracking bank. If you choose a preset map and still have difficulty following complete conversations, then you’ll have to program your own Fleet Map.

Care and Maintenance
General Use
Turn the scanner off before disconnecting the power or replacing the batteries.
Always write down the programmed frequencies in the event of memory loss.
If memory is lost, simply reprogram each channel. The display shows there has been a memory loss.
Always press each button firmly until you hear the entry tone for that key entry.
Location
Do not use the scanner in high-moisture environments such as the kitchen or bathroom.
Avoid placing the unit in direct sunlight or near heating elements or vents.
If the scanner receives strong interference or electrical noise, move it or its antenna away from the source of the noise. If possible, a higher elevation, may provide better reception. Also try changing the height or angle of the antenna.
000.000 in all channels when
Cleaning
Disconnect the power to the unit before cleaning. Clean the outside of the scanner with a mild
detergent. To prevent scratches, do not use abrasive cleaners or solvents. Be careful not to rub the LCD window.

User Defined Fleet Maps
Type I Programming Information
When a Type I system is designed, the address information for all the IDs is divided into 8 equal sized blocks, numbered 0–7. When you program your scanner to track a Type I system, you must select a size code for each of these blocks. When you have assigned a size code to all 8 blocks, you’ll have defined the Fleet Map for the system you’re tracking. Each size code determines the number of Fleets, Subfleets, and IDs each block will have. For example, a size code of S-4 has one Fleet, which is divided into 16 separate Subfleets, and it has a total of 512 individual IDs.
When a block is assigned a size code, the Fleet or Fleets created within the block are assigned a Type I ID. The way these IDs display on your scanner depend on the block number and the block’s size code. When a Type I ID displays, the leftmost digit represents the block which contains the ID. The next two digits identify which Fleet is active, and the last digit(s) identifies the Subfleet.
405-12

(1 digit)
Subfleet

(2 digits)
The details concerning how the size codes are selected by a Type I System designer are highly dependent on the specific needs of the system’s users. Some organizations may want many subfleets with only a few radios each, while another organization may want only a few subfleets with many radios each. Your task is to program your fleet map with the same size code assignments as the trunked system. If you do this accurately, you’ll track all the Fleet-Subfleet combinations used by the system. In other words, you’ll hear complete communications while monitoring a trunked system.

If you don’t already know the size codes used, you’ll have to guess at them. But since you don’t have to figure out all the blocks at once, this isn’t as hard as it seems. Select a size code for a block, and then press
. Now listen to the

communications. If you decide you are receiving most of the replies to the conversations with IDs assigned to the block you just programmed, then you’ve probably selected the right size code and can work on the next block of the map.
Finally, for most public safety systems there are some size codes which are more common. S-3 and S-4 are probably the most common, followed by S-10, S-11, and S-12.

Size Code Restrictions
If you select size code S-12, S-13, or S-14, there are some restrictions as to which blocks can be used for these codes.
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 when programming a Fleet Map. For example, if you assign Block 0 as an S-12, you will be prompted for b2, the next block available, instead of b1. And if you assign Block 0 as an S-14, you would not see another prompt because it uses all available blocks.

Precautions

Before you use this scanner, please read and observe the following:
EARPHONE WARNING!
Be sure to use only the recommended optional monaural earphone (EP009). You may also use a 32Ω stereo headset. Use of an incorrect earphone or stereo headset may be potentially hazardous to your hearing. The output of the phone jack is monaural, but you will hear it in both headphones of a stereo headset. Set the volume to a comfortable audio level coming from the speaker before plugging in the monaural earphone or a stereo headset of the proper impedance (32Ω). Otherwise you might experience some discomfort or possible hearing damage if the volume suddenly becomes too loud because of the Volume Control or Squelch Control setting. This may be particularly true of the type of earphone that is placed in the ear canal.
WARNING!
Uniden does not represent this unit to be waterproof. To reduce the risk of fire or electrical shock, do not expose this unit to rain or moisture.
