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.
