Understanding Signal Strength
The quality of each call you make or receive, is dependent upon the
signal strength in your area. Your phone informs you of the current
signal strength by displaying a icon. The more bars displayed, the
stronger the signal. The signal strength indicator (
) displays in
the upper left corner of your display screen. The voice quality of your
phone is always clearest when the antenna is fully raised.If you’re
inside a building, reception may be better near a window.
Understanding the Power Save Mode
If you are trying to use your phone in an area where the signal is too
weak, the Power Save feature automatically activates to conserve
battery power when you have been unable to pick up a signal for 15
minutes. If your phone is on, it periodically rechecks service
availability. To manually check, press any key. A message is displayed
on the screen any time Power Save has been activated. 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 is
turned on, it receives and transmits radio frequency (RF) signals.
When your phone is in use, the system handling your call controls the
power level. This power can range from 0.006 watts to 0.2 watts in
digital mode.
