    Note:You will now begin to see Type I
    Fleet-Subfleet IDs. For example, 100-12, 100-9,
    000-12, 400-8, etc. See User Defined Fleet Maps
    in the Appendix for more information about Type I
    IDs.
    How do you know if the preset map is correct? You’ll have
    to listen to see if you’re following complete conversations.
    If not, you should try another preset map.
    Programming a Fleet Map
    You may want to read User Defined Fleet Maps in the
    Appendix before programming a fleet map. It contains a
    detailed explanation of Scanner Fleet Map Programming,
    as well as a table listing the Fleet Map Size Codes.
    1. Select the Trunking
    Programming mode
    and the bank you
    want to change.
    2. Press

    For specifics about
    each size code, see
    Fleet Map Size
    Codes in the
    Appendix.
    10. PressR.
    The scanner exits the
    Trunking
    Programming mode,
    acquires the data
    channel, and begins
    searching using the
    map you’ve
    programmed.
    Programming a Hybrid System
    A Hybrid system is simply a Type I system with some
    blocks designated as Type II blocks. To program a Hybrid
    system, follow the steps listed in Programming a Fleet Map
    in the previous section. However, if you want a block to be
    Type II, select Size Code S-0.
    When you begin searching a trunking bank with a Hybrid
    Fleet Map, you will see both types of system IDs. That is,
    Type II IDs usually appear as an even number without a
    dash; Type I IDs appear as a three or four digit number,
    followed by a hyphen, followed by a one or two digit
    number. See page 61 for more information.

    							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
    000.000in all channels when
    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.
    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.
    Do not use excessive amounts of water.
    54 
    						
    							Repairs
    Do not attempt any repair. The scanner contains
    no user serviceable parts. Contact the Uniden
    Customer Service Center or take it to a qualified
    repair technician.
    Birdies
    All radios can receive “birdies” (undesired signals).
    If your scanner stops during Scan mode and no
    sound is heard, it may be receiving a birdie. Birdies
    are internally generated signals inherent in the
    electronics of the receiver.
    Press
    Oto lockout the channel, and then press
    Sto resume scanning.
    55 
    						
    							Troubleshooting
    If yourBC 235XLTis not performing properly, try the
    following steps.
    Problem Suggestion
    Scanner won’t work. 1. Check the connections at both ends of
    the AC Adapter.
    2. Turn on the wall switch of your room. You
    could be using an outlet controlled by the
    wall switch.
    3. Move the AC Adapter to another wall
    outlet or replace the battery pack.
    Improper reception. 1. Check the antenna connection or move
    and reposition the antenna.
    2. Move the scanner.
    3. You may be in a remote area which could
    require an optional multi-band antenna.
    Check with your dealer or local
    electronics store.
    Scan won’t stop. 1. Adjust squelch threshold - refer to
    page 15, Setting the Squelch.
    2. Check the antenna connection.
    3. Check to see if many of the channels are
    locked out. If so, the scanner has less
    chance of finding an active channel.
    4. Review each channel’s frequency to see
    if it is still stored in memory and is correct.
    5. It’s possible that none of the programmed
    frequencies are currently active.
    Scan won’t start. 1. Press the
    Skey again.
    2. Adjust the
    SQUELCHcontrol.
    3. Check to see if all channels are locked
    out.
    Weather Scan won’t work. 1. Adjust squelch threshold - refer to
    page 15, Setting the Squelch.
    2. Check the antenna.

    							If you experience difficulty while inTrunkTracker™mode,
    try the following steps.
    Problem Suggestion
    Scanner won’t track the
    trunked system.1. May not be a system which can be
    tracked by your scanner.
    2. Missing the data frequency.
    3. Change to a Type 1 Scanner setup.
    Review Fleet Map Programming on
    page 50.
    Scanner won’t stop during
    Scan List mode.1. No IDs have been programmed.
    2. The IDs you have stored are not active.
    Scanner will not acquire
    data channel.1. Adjust the squelch for trunking mode.
    See page 37.
    2. Missing the frequency used for the data
    channel. Check your frequency list.
    Missing replies to
    conversations.1. Change to a Type 1 Scanner setup.
    Review Fleet Map Programming on
    page 50.
    2. Try another Preset Fleet Map or Program
    your own Fleet Map.
    3. Check to see that all of the systems
    frequencies have been entered.
    Channel Activity Indicators
    are flashing but no sound
    is heard.1. May be a private or telephone
    interconnect call, which are intentionally
    blocked by your scanner.
    2. The ID in your display is not active.
    If you still cannot get satisfactory results while using your
    scanner or if you want additional information, please call or
    write the Uniden Parts and Service Division. The address
    and phone number are listed in the Warranty at the end of
