The voice quality of your phone will always be at its best when
the antenna is fully raised. If you’re inside a building, reception
may be better near a window.
The quality of each call you make or receive depends on the
signal strength in your area. Your phone will inform you of the
current 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.

If you’re 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’ve 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.

Your phone is basically a radio transmitter and receiver. When
it’s 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 product meets all FCC
requirements for RF power output levels for this handset type.
