Keeping tabs on signal strength.
 
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.
 
Understanding Power Save mode.
 
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.
