Understanding signal strength
The quality of each call you make or receive, is dependent upon the signal
strength in your area. Your phone will inform 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. The signal strength indicator ( )
displays in the upper left corner of your display screen. The voice quality of
your phone will always be at its clearest when the antenna is fully raised. If
you’re inside a building, reception may be much 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 will automatically activate to conserve battery power when
you have been unable to pick up a signal for 15 minutes. If your phone is on, it
will periodically recheck service availability, or you can do so yourself
manually by pressing any key. A message will be 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.
