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.
The screen displays used in this manual are representations of what might appear when you use your scanner.

What is Scanning?
Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. The

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

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.

Setup
These are helpful guidelines when using your new scanner:
If your scanner receives interference or electrical noise, move the scanner or its antenna away from the source.
If you need to improve reception, use an optional antenna designed for multi-band coverage. (You can purchase this type of antenna at a local electronics store.)
Use the included earphone or an optional stereo headset with proper impedance for private listening. Read the precautions on the inside front cover of this Guide.
Installing the Batteries
1. Open the cover.
2. Insert the battery pack.

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.

Scanning
1. After programming frequencies, simply press scanning.
2. The indicator for each bank which will be scanned appears in the display, while the bank being currently monitored flashes. You can deselect banks from active scanning by pressing their number on your keypad. The indicator for each deselected bank turns off, and the bank’s channels are not scanned.
Note: One Bank must always be active. You cannot deactivate all ten banks at the same time. If you try to turn all the banks off, the first bank is automatically selected.
To restore a bank to active scanning, press the bank’s number on your keypad. The bank’s indicator will display again.
