Getting the most out of your reception
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 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.
