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.
The phone is not ringing when a call is received.
Check the Sounds menu to make sure the
phone is not set for Silent Mode.
The phone becomes warm during long calls.
This is not a problem. Because of its size,
the phone may feel slightly warm during
extended calls.
The 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 function on the multicharger to
condition the battery.
Calls are being dropped.
You are probably in a geographic area with
minimal 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 service provider.
The signal strength varies.
This is a common occurrence. Transmitter
sites are set in geographic areas, and
coverage is not 100% all of the time. Signal
strength varies as you travel between cells.
