Important Information About Your Phone and Service

Keeping Tabs on Signal Strength
The quality of each call you make or receive depends on the
signal strength in your area. Your phone informs you of the
current signal strength by displaying a number of bars next to
the signal strength icon. The more bars displayed, the stronger
the signal. If you're inside a building, being near a window may
give you better reception.
Understanding the Power Save Feature
If your phone is unable to find a signal after 15 minutes of
searching, a Power Save feature is automatically activated. If
your phone is active, it periodically rechecks service availability
or you can check it yourself by tapping any key. Anytime the
Power Save feature is activated, a message displays on the screen.
When a signal is found, your phone returns to Standby mode.
Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When
it's turned on, it receives and transmits radio frequency (RF)
signals. When you use your phone, the system handling your call
controls the power level. This power can range from 0.006 watts
to 0.2 watts in digital mode.
