Troubleshooting
Q. I pressed the power button, but nothing happened. What’s 
wrong with my phone?

. How do I unlock my phone?
A. Try entering the last three digits of your wireless number. If that does not 
work, try using the factory preset lock code: 123. If this fails, call your 
Service Provider (the company that sends you your monthly wireless bill) 
for assistance. For more information on your phone’s security features, see 
the Lock/Security chapter, page 82.
Q. My battery did not 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 
sensitive to high temperature extremes. It is a good idea to always take your 
phone with you when you leave your car.
Q. I tried to place a call and received a fast busy signal.
A. This sound means that your call was not processed. For example, the 
network may be temporarily busy. To redial the number, press the Smart 
Button or press æ (or ª) before ending your call attempt, or press º 
and try the call again later. See page 97 for more information on redialing.
