Uniden BC 235XLT Scanner Operating Guide

Quick Start Guide

The Uniden BC 235XLT is a 300-channel trunk tracking scanner designed to monitor various radio communications, including police, fire, emergency, marine, air, and amateur bands. To begin, ensure the batteries are installed and charged, the antenna is attached, and frequencies are programmed into the scanner's memory.

Setup and Installation

• Batteries: Open the battery cover and insert the battery pack.
• Charging: Use the supplied AC Adapter (AD70U) to charge the battery. A full charge takes 14–16 hours. You can use the scanner while it charges.
• Antenna: Attach the flexible antenna to the BNC connector on top of the unit.
• Belt Clip: Attach the belt clip using the provided screws, being careful not to overtighten.

Basic Operation

• Squelch Setting: To set the squelch, enter Manual mode. Turn the SQUELCH control fully clockwise until you hear a hiss, then turn it counter-clockwise just until the hiss stops. This ensures only clear signals are received.
• Keylock: Press and hold the LOCK key to prevent accidental key entries.
• Scanning: Press the SCAN key to begin scanning programmed channels.

Programming Frequencies

Before scanning, you must program frequencies into the scanner's channels:

1. Press the MANUAL key.
2. Enter the desired channel number and press MANUAL again.
3. Enter the frequency and press the ENTER key.
4. If you make a mistake, press the decimal key twice to clear and start over.

Trunk Tracking

The BC 235XLT supports Motorola Type I, Type II, Type IIi, and Hybrid trunking systems. To track a trunked system:

• Programming: You must enter trunking frequencies while in Trunking Programming mode.
• Operation: Press the TRUNK key to toggle between conventional and trunk tracking modes.
• Fleet Maps: If you are missing conversations, you may need to select a different preset Fleet Map or program a custom one.

Scan Lists

Scan Lists allow you to organize trunking system users into categories. Each trunk tracking bank has 5 Scan Lists, with each list holding up to 10 IDs. You can program these manually or during trunking search mode.

Care and Maintenance

• Cleaning: Disconnect power before cleaning. Use a mild detergent and a soft cloth. Do not use abrasive cleaners or excessive water.
• Repairs: The scanner contains no user-serviceable parts. Contact Uniden Customer Service for repairs.

Troubleshooting

• Scanner won't work: Check AC adapter connections and the battery pack.
• Improper reception: Reposition the antenna or move the scanner.
• Scan won't stop: Adjust the squelch threshold or check for locked-out channels.
• Scanner won't track trunked system: Ensure you have the correct data frequency and system type.
