Troubleshooting
Question Answer
I pressed the
power button, but
nothing happened.
What’s wrong with
my phone?
Make sure that you press and hold the power button
until the display appears and you hear an audible alert. If
nothing still happens, then check that you have installed
a battery and that the battery is charged. For more
information about batteries and charging see the
sections on batteries starting with “Installing and
Removing Batteries” on page 18.
My battery didn’t
last as long as I
expected. What
can I do to extend
battery life?
Your battery’s “standby-time” is a relative measurement
of the battery’s capacity. The more you talk on the
phone, the less standby time you have, and vice versa.
To get the most from your battery, allow it to charge
fully. To charge the battery to 100% of its capacity, leave
it in the charger for an extra hour after the charger’s light
turns green.
You can also turn on the Power Save Mode feature to
extend battery life. However, the LED Power/Status
Indicator does not light when this feature is activated.
Certain features demand power from your battery and
reduce battery life. If you have selected the Automatic
Display of Individual Call Timer feature, the display uses
battery power to remain active during each call. Turn this
feature off to conserve battery energy. (See “Displaying
the Individual Timer Automatically” on page 71 for more
information on this feature.)
Make sure that you are calling in Digital mode.
Make sure that you are using batteries that are
compatible with your phone.
Exposing your battery to extreme temperatures—below
-10°C (14°F) or above 45°C (113°F)—can shorten battery
life. Batteries are especially sensitive to high
temperature extremes. As a good rule, always take your
phone with you when you leave your car.
The display says,
“Locked.” How do I
unlock my phone?
Enter the last three digits of your cellular number. If that
doesn’t work, use the factory preset lock code: 123. If
all else fails, call your Service Provider (the company
that sends you your monthly cellular bill) for assistance.
(See “Locking/Unlocking Your Phone” on page 83 for
more information on Security Features.)
