    							Introduction
    The BC860XLT is a new state-of-the-art radio with automatic
    scanning capabilities.  Store frequencies into 10 banks of 10 channels
    each.  Scan all 100 channels at Turbo Scan speed.
    What is Scanning?
    Unlike standard AM or FM radio stations, most two-way
    communications (listed on the next page) do not transmit continuously.
    The BC860XLT scans 
    programmed
     channels at the rate of nearly
    100 channels per second until it finds an active frequency.
    Scanning stops on an active frequency, and remains on that channel
    as long as the transmission continues.  When the transmission ends,
    the scanning cycle resumes until another transmission is received.
    While the BC860XLT scans channels, it is in Scan mode.  When
    you stop scanning with 
    M
    , it is in Manual mode.
    What is Searching?
    The BC860XLT can search 12 bands to find active frequencies.
    This gives you the opportunity to find new frequencies that have not
    been programmed.
    Choose between two speeds for the search feature: Normal
    (100 steps per second) or Turbo Search (300 steps per second).
    While the BC860XLT searches for active frequencies, it is in Search
    mode or Turbo Search mode.  When you stop the search with 
    H
    ,
    it is in Search Hold mode.

    							Feature Highlights
    100 Channels
     – Program one frequency into each channel.  You
    must have at least one channel programmed to use the Scan
    mode.29 MHz - 956 MHz
     – Scan these frequency ranges with your
    scanner.  (Note:
     the frequency coverage is not totally continuous
    from 29.0 MHz to 956 MHz.)10 Priority Channels
     – Assign one Priority channel in each bank.
    Keep track of the activity on most important channel(s) while
    monitoring others.Data Skip
     – Skip data signals and unmodulated transmissions.Manual Channel Access
     – Go directly to any channel.Memory Backup
     – Frequencies programmed in the channels are
    retained in memory. If the power is disconnected, the memory
    retains the frequencies for 7 days.Twin Turbo
    TM Speed
     – With both Turbo Scan and Turbo Search,
    your BC
    860XLT
     is truly a Twin Turbo
    TM Scanner.
    Weather Scan
     – Use as a weather information radio.
    Scanner Care &
    Safety Tips
    Do not use the scanner in high-moisture areas such as the 
    kitchen or bathroom.Do not plug the scanner into an outlet controlled by a wall switch
    as prolonged periods without power causes scanner memory loss.Avoid placing the unit in direct sunlight or near heating elements
    or vents.

    							Where to Obtain
    More Information
    Before you can scan, you must program a frequency into each
    channel you want to use.  The “
    Betty Bearcat Starter Frequency
    Guide
    ” lists typical frequencies used around the U.S. that you may
    program into the BC
    860XLT
    .
    If the frequencies listed in the “
    Betty Bearcat Starter Frequency Guide
    ”
    do not work in your area, call the enclosed “Mr. Scanner
    ” 800 number.
    A Uniden representative should be able to provide you with a few
    sample frequencies.  Or, use the enclosed order form to purchase a
    local frequency list.
    The Bearcat Radio Club and other similar hobby clubs have
    publications, information on computer bulletin boards, and even
    contests for the radio enthusiast.  
    Also, your local library has more information.

    							Setup
    Note
    Extend the antenna to its full height.  For UHF
    frequencies, shortening the antenna may
    improve the reception.If your scanner receives strong interference or
    electrical noise, move the scanner or its
    antenna away from the source.If you are operating the scanner in a fringe area
    or 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.) 
    If the plug at the end of the cable does not
    match the antenna jack, you may need to
    purchase an adapter.Plug an optional external speaker 
    (ESP25, 8 ohms) into the EXT.SP jack.
    Warning!Use only the supplied AC Adapter - AC144U

    							Basic Operation
    Note: Fold out the illustration from the Back Cover to see the Controls and Indicators while reading this Guide.
    How Squelch WorksThink of “SQUELCH” as a gate.  If the
    gate is too low (squelch too low),
    everything (all noise as well as signals)
    gets through.If the gate is set too high (squelch too
    high), nothing gets through.If the gate is set just right (squelch set
    properly), just the desired signals get
    through.The BC
    860XLT
     Squelch has two options.  AUTO 
    Squelch 
    - a level preset at the factory; 
    and Manual Squelch, where you can set the squelch level as needed by conditions.
    9 
    						
    							Setting the SquelchAdjust VOLUME
     to a comfortable listening level.Auto SquelchAUTO is a compromise between tight
    and threshold.  It is a convenience for
    listening to stronger signals.
    ê
    Note:  Be sure that the Squelch control
    clicks
     into the 
    AUTO position.
    Manual SquelchTo manually set the Squelch, you must
    be in the Manual Mode.
    No signal should be present when
    adjusting squelch.
    Press 
    M
     until you 
    do not hear
    a signal.Turn until hiss heard.
    This lowers the “squelch gate,” allowing
    all signals and noise to get through.Turn just until hiss stops.
    This raises the “squelch gate” allowing
    only strong signals to get through.
