    BASIC OPERATION
    Dial select functionUse the dial select function to adjust the tuning behavior of
    the [Y]/[Z] keys—use 1 MHz tuning when you want to
    change the frequency in large increments; use regular tuning
    when you want to change the frequency in  smaller incre-
    ments.
    qPush [V/M] to select VFO
    mode.
    wPush [V/M] for 2 sec. one or
    more times to select the de-
    sired tuning increment.
    - 1 MHz tuning, 100 kHz tun-
    ing or regular tuning steps
    can be selected. (see dia-
    grams at right)
    ePush any key to return to nor-
    mal operation.
    NOTE: Large tuning steps should be used only when you
    want to change the frequency in large increments please se-
    lect regular tuning steps for normal operation.

    OTHER FUNCTIONS
    Initial set modeInitial set mode is accessed at power ON and allows you to
    set seldom-changed settings, in this way you can “customize”
    transceiver operations to suit your preferences and operating
    style.DEntering initial set modeqWhile pushing [V/M] + [ ],turn power ON.
    • The transceiver enters initial set mode and “mn”, “bP” or “St” ap-

    mally sound when you push a
    key. These can be turned ON or
    OFF as you prefer.DSide tones ON/OFFWhen using an optional headset
    such as those from the David

    							Charging
    precautionsNEVER attempt to charge dry cell bat-
    teries. This will cause internal liquid
    leakage and damage the battery case
    and transceiver.
    NEVER connect two or more chargers
    at the same time.
    Charging may not occur under temper-
    atures of 10°C (50°F) or over tempera-
    tures of 40°C (104°F).
    When using BC-119:If the charge
    indicator flashes orange, vehicle bat-
    tery voltage is low and charging is
    not possible. Check the vehicle bat-
    tery voltage in this case. If the
    charge indicator flashes red, there
    may be a problem with the battery
    pack (or charger). Re-insert the bat-
    tery pack or contact your dealer.
    Battery pack
    chargingThe BP-195 or BP-196 
    BATTERY PACK
    includes rechargeable Ni-Cd batteries
    and can be charged approx. 300 times.
    Charge the battery pack before first op-
    erating the transceiver or when the bat-
    tery pack becomes exhausted.
    If you want to be able to charge the bat-
    tery pack more than 300 times, the fol-
    lowing points should be observed:
    1. Avoid overcharging. The charging pe-
    riod should be less than 48 hours.
    2. Use the battery until it becomes al-
    most completely exhausted under
    normal conditions. We recommend
    battery charging just after transmitting
    becomes impossible.
    D
    Rapid charging with the BC-119
    The optional BC-119 provides rapid
    charging of battery packs.
    One AD-81 and an AC adapter (may be
    supplied with the BC-119 depending on
    version) are additionally required.• Charging periods: 1.5 hours (w/BP-195)

    BATTERY PACKS
    About the battery packDOperating periodDepending on the attached battery pack, the operating period
    of the transceiver varies. Refer to the last page for battery
    pack specifications.DBattery pack lifeIf your battery pack seems to have no capacity even after
    being fully charged, completely discharge it by leaving the
    power ON overnight. Then, fully charge the battery pack
    again.
    If the battery pack still does not retain a charge (or very little),
    a new battery pack must be purchased.DRecycling information (U.S.A only)
    The product that you have purchased may
    contain a rechargeable battery. The battery
    is recyclable. At the end of its life, under var-
    ious state and local laws, it may be illegal to
    dispose of this battery into the municipal
    waste stream. Call 1-800-8-BATTERY for
    battery recycling options in your area or contact your dealer.
    Installing batteries in the
    battery caseWhen using a battery case, install 8 AA (R6) size Ni-Cd or al-
    kaline batteries as illustrated below.
    qRemove the bat-
    tery case from the
    transceiver.
    wInstall 8 ×AA (R6)
    size Ni-Cd or alka-
    line batteries.
    •Be sure to observe
    the correct polarity.
    NEVERconnect DC power to the transceiver when in-
    stalling dry cell or alkaline batteries. Such a connection will
    damage the transceiver.
    Be careful of battery overcharging. When operating via ex-
    ternal DC power, installed batteries are simultaneously
    charged.
    Keep battery contacts clean. It’s a good idea to clean bat-
    tery terminals once a week.

    Cloning allows you to quickly and easyly
    transfer the programmed contents from
    one transceiver to another transceiver, or,
    data from PC to a transceiver using the optional EX-2119
    cloning software.DTransceiver to transceiver cloningqConnect the OPC-474 
    CLONING CABLE 
    with adapter plugs to
    the [SP] jack of the master and slave transceivers.
    •The master transceiver is used to send data to the slave trans-
    ceiver.
    wWhile pushing [Y] + [Z] + [V/M], turn power ON to enter
    cloning mode (master transceiver only—power ON only for
    slave transceiver).
    •“CLonE” appears and the
    transceivers enter the clone
    standby condition.
    ePush [PTT] on the master

    ter transceiver’s display.
    •“CL in” appears automati-
    cally in the slave trans-
    ceiver’s display.
    eWhen cloning is finished, turn
    power OFF, then ON again to
    exit cloning mode.
    DCloning using PCData can be cloned to and from a PC (IBM compatible) using
    the optional EX-2119

    DCloning error
    NOTE: DO NOTpush [PTT] on the slave transceiver dur-
    ing cloning. This will cause a cloning error.
    When the display at right ap-
    pears, a cloning error has oc-
    curred.
    In this case, both transceivers automatically return to the
    clone standby condition and cloning must be repeated.
