Unable to Place Call!

    The signal is too weak to make a call.  Try again when the signal
    strength is one bar or stronger.

System Busy

    The cellular system is busy with other calls.  Wait a while and try
    your call again.

Call is Restricted! Home 1

    You called a number for which you have set call restrictions.  See the
    Locks menu for changing call restrictions.

Wrong Security Code!

    You entered an incorrect security code.  Enter the correct security
    code.

Low Battery! Home 1

    Battery power is low.  When the phone shuts itself off, replace the
    battery with a fully charged one, or use an alternate power source,
    such as a travel charger

    Your text message memory is full.  Erase some stored messages before
    you can receive more messages.

Ready RoamA

    The Roam indicator lets you know that you are no longer operating in
    your home cellular system.  Check with the system operator for roaming
    arrangements, rates, and coverage areas in the U.S.A., system operators
    can typically be contacted by calling *611 or 611.

Problems and Possible Solutions

The phone does not turn ON

    Recharge or replace the battery

    If you are using a battery eliminator, make sure that the battery
    eliminator is fully inserted into the vehicle cigarette lighter. Make
    sure the vehicle is supplying power to the cigarette lighter.

Phone is not ringing when a call is received

    Check the Sounds menu to make sure the phone is not set for Silent Mode.

Phone becomes warm during long calls

    This is not a problem. Because of its size, the phone may feel slightly
    warm during extended calls.

Battery does not seem to charge to full capacity

    Condition the Battery by fully discharging and charging it three times.
    Or, if your phone came with a multicharger, use the conditioning func-
    tion on the multicharger to condition the battery.

Dropping calls

    You are probably in a geographic area with minimal cellular service.
    Wait until the signal strength indicator in your phone's display shows
    a high relative signal strength (more bars) before trying a call. Make
    note of geographic locations where calls are dropped and contact your
    cellular carrier.

Varying signal strength

    This is a common occurrence. Cellular sites are set in geographic areas
    and coverage is not 100% all of the time. Signal strength varies as you
    travel between cells.
