Understanding the Power Save Feature If your phone is unable to find a signal after 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 pressing 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.

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 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 pressing 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.
