The voice quality of your phone will always be at its best
when the antenna is not obstructed. 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 immediate area. When turned on, your
phone will always give you a visual indication of the signal
strength in your immediate area. The visual indicator is
always in the upper left corner of your display and is referred
to as the signal strength indicator:
. More lines indicate
more signal strength. Four lines indicate maximum strength
and one line indicates least strength.

If you’re trying to use your Sprint PCS 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.
