Troubleshooting
Q. I pressed the power button, but nothing happened. What’s wrong with my
phone?
A. Check that you have installed a battery and that the battery is charged. See
page 14 for information about installing your battery.
Q. The display says Locked . How do I unlock my phone?
A. Try entering the last three digits of your cellular number. If that doesn’t
work, try using 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. For more information on your phone’s security features, see the
Lock/Security chapter, page 78.
Q. My battery didn’t last as long as I expected. What can I do to extend battery
life?
A. To get the most from your battery, make sure it is fully charged. 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.
Exposing your battery to extreme temperatures—below -10
°
C (14
°
F) or
above 45
°
C (113
°
F)—can shorten battery life. Batteries are especially sensi-
tive to high temperature extremes. As a good rule of thumb, always take your
phone with you when you leave your car.
