Troubleshooting
Q. I pressed the power button, but nothing happened. 
What’s wrong withmy phone?
A. Check that you have installed a battery and that the 
battery is charged. See pages 21-33 for more 
information about batteries and charging.
Q. My battery didn’t last as long as I expected. What can I 
do to extend battery life?
A. Keep in mind that your battery’s “talk-time” and 
“standby-time” are a relative measurement of the 
battery’s capacity. The more you talk on the phone, the 
less standby-time you will have and vice versa.
To get the most from your battery, make sure you allow it to 
fully charge. 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.
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 page 96 for more information 
on this feature.)
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 of thumb, always take your phone 
with you when you leave your car.
