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 you activate Power Save. 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 0.6 watts to 0.2 watts in digital mode.
