    lets you in on all the action!
    This scanner gives you di-
    rect access to over 23,000
    exciting frequencies, includ-
    ing those used by police and
    fire departments, ambu-
    lance services, aircraft,
    transportation services, and
    amateur radio. You can se-
    lect up to 200 channels for
    your scanner to scan and
    you can change your selec-
    tion at any time.
    Your scanner also has these
    special features:
    Weather Alert 
    — the scan-
    ner automatically sounds an
    alert when it receives a
    weather emergency signal.
    Weather Band Key 
    —

    grammed weather frequen-
    cies to keep you informed
    about current weather condi-
    tions.
    Wired Programming 
    — you
    can connect your scanner to
    a personal computer and
    program frequencies into thescanner from the computer
    using an optional cable and
    software.
    Note:
     The necessary cable
    and software, and additional
    information about using your
    personal computer to pro-
    gram your scanner, are
    available at your local Ra-
    dioShack store.
    Liquid Crystal Display
     —
    makes it easy to view and
    change programming infor-
    mation.
    Search Skip

    — lets you
    search for a transmission
    starting from a specified fre-
    quency.
    Ten Channel-Storage Banks
    — you can store 20 chan-

    							3 Ten Monitor Memories 
    —
    let you temporarily save up
    to ten frequencies you locate
    during a search, so you can
    move selected frequencies
    to channel storage later.
    Scan Delay
     — delays scan-
    ning for about 2 seconds be-
    fore moving to another
    channel, so you can hear
    more replies that are trans-
    mitted on the same channel.
    You can also set the scan-
    ner to delay on all active fre-
    quencies during a search.
    Memory Backup
     — keeps
    the channel frequencies
    stored in memory for an ex-
    tended time even if the scan-
    ner loses power.
    Three Power Options 
    —
    you can power the scanner
    from internal (rechargeable
    or non-rechargeable) batter-
    ies or external AC or DC
    power (using an optional AC
    or DC adapter).
    Low Battery Alert 
    — warns
    you when the battery power
    gets low.
    Key Lock 
    — lets you lock
    the scanner’s keys to help
    prevent accidentally chang-ing the scanner’s program-
    ming.
    Key Confirmation Tones
    — the scanner sounds a
    confirmation tone when you
    perform an operation cor-
    rectly and an error tone if
    you make an error.
    Lockout Function
     — lets
    you set the scanner to ig-
    nore specified channels
    when scanning.
    Ten Priority Channels
     —
    let you set the scanner to
    check up to ten channels ev-
    ery 2 seconds so you do not
    miss important calls.
    Display Backlight
     —
    makes the scanner easy to
    read in low-light situations.
    Supplied Flexible Antenna
    with BNC Connector 
    —
    provides good reception of
    strong local signals. You can
    connect an external anten-
    na with a BNC connector to
    the scanner for improved re-
    ception of distant/weaker
    signals.

    FCC NOTICE
    Your scanner might cause
    radio or TV interference
    even when it is operating
    properly. To determine
    whether your scanner is
    causing the interference,
    turn off your scanner. If the
    interference goes away,
    your scanner is causing it.
    Try the following methods to
    eliminate the interference:
    • Move your scanner
    away from the receiver.
    • Connect your scanner to
    an outlet that is on a dif-
    ferent electrical circuit
    from the receiver.
    • Contact your local
    RadioShack store for
    help.
    Note:
     Mobile use of this
    scanner is unlawful or re-
    quires a permit in some ar-
    eas. Check the laws in your
    area.
    SCANNING 
    LEGALLY
    Your scanner covers fre-
    quencies used by many dif-
    ferent groups including
    police and fire departments,
    ambulance services, govern-
    ment agencies, private com-
    panies, amateur radio
    services, military opera-
    tions, pager services, and
    wireline (telephone and tele-
    graph) service providers. It is
    legal to listen to almost ev-
    ery transmission your scan-
    ner can receive. However,
    there are some transmis-
    sions you should never in-
    tentionally listen to. These
    include:
    • telephone conversa-
    tions (cellular, cordless,
    or other private means
    of telephone signal
    transmission)
    • pager transmissions
    • any scrambled or
    encrypted transmissions
    According to the 
    Electronic
    Communications Privacy Act
    (ECPA), you are subject to
    fines and possible imprison-
    ment for intentionally listen-
    ing to, using, or divulging the
    20-313.fm  Page 5  Friday, January 7, 2000  3:09 PM 
    						
    							6contents of such a transmis-
    sion unless you have the
    consent of a party to the
    communication (unless such
    activity is otherwise illegal).
    This scanner is designed to
    prevent reception of illegal
    transmissions, in compliance
    with the law which requires
    that scanners be manufac-
    tured in such a way as to not
    be easily modifiable to pick
    up those transmissions. Do
    not open your scanners
    case to make any modifica-
    tions that could allow it to
    pick up transmissions that it
    is not legal to listen to. Doing
    so could subject you to legal
    penalties.
    We encourage responsible,
    legal scanner use.

    PREPARATION
    INSTALLING 
    BATTERIES
    You can power your scanner
    with four AA batteries (not
    supplied). For the best per-
    formance and longest life, we
    recommend RadioShack al-
    kaline batteries. Or, you can
    use rechargeable nickel-
    cadmium or nickel-metal hy-
    dride batteries. Both types of
    batteries are available at
    your local RadioShack store.
    Cautions:
    • The scanner has a built-
    in circuit that lets you
    recharge nickel-
    cadmium batteries in-
    side the battery com-
    partment. However, you
    must never use this cir-
    cuit when you have
    installed non-
    rechargeable batteries
    in the scanner. Be sure
    to read “Important Infor-
    mation About the Exter-
    nal Power Jacks” on
    Page 10 and “Charging
    Rechargeable Batter-
    ies” on Page 12.
    • Use only fresh batteries
    of the required size and
    recommended type.
    • Do not mix old and new
    batteries, different typesof batteries (standard,
    alkaline, or recharge-
    able), or rechargeable
    batteries of different
    capacities.
    Follow these steps to install
    batteries.
    1. While pressing down on
    the tab on the bottom of
    the battery compart-
    ment cover, pull it away
    from the scanner to
    remove it.
    2. Install two batteries in
    the battery compart-
    ment and two in the
    cover as indicated by
    the polarity symbols (+
    and –) marked on the
    inside of the battery
    compartment and inside
    the cover. 
    20-313.fm  Page 9  Friday, January 7, 2000  3:09 PM 
    						
    							10
    3. Replace the cover.
    When 
    BATT.Lo flashes and
    the scanner beeps every 15
    seconds, or if the scanner
    stops operating properly, re-
    place or recharge the batter-
    ies.
    Warning: 
    Dispose of old bat-
    teries promptly and properly.
    Do not burn or bury them.
    Caution:
     If you do not plan to
    use the scanner with batter-
    ies for a month or more, re-
    move the batteries. Batteries
    can leak chemicals that can
    destroy electronic parts.
    IMPORTANT 
    INFORMATION 
    ABOUT THE 
    EXTERNAL 
    POWER JACKS
    The scanner has two exter-
    nal power jacks  — 
    POWER
    and CHARGE. It is important
    that you understand the pur-
    pose of each jack before you
    connect any adapter to the
    scanner.
    The 
    POWER jack lets you
    power the scanner using an
    external power source (AC
    or DC adapter). Connecting
    an adapter also disconnects
    the internal batteries. 
    The 
    CHARGE jack supplies
    power to operate the scan-
    ner and also charges the in-
    ternal batteries. Use the
    CHARGE jack only when you
    have installed rechargeable
    nickel-cadmium batteries.
