Product Performance
Getting the Most Out of Your Signal Reception
The quality of each call you make or receive depends
on the signal strength in your area. Your phone
informs 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.
If you're inside a building, being near a window may
give you better reception.
Understanding the Power Save Feature
If your phone is unable to find a signal after
searching, a Power Save feature is automatically
activated. If your phone is active, it periodically
rechecks service availability or you can check it
yourself by pressing any key.
Anytime the Power Save feature is activated, a
message displays on the screen. 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's turned on, it receives and
transmits radio frequency (RF) signals. When you use
your phone, the system handling your call controls
the power level. This power can range from 0.006
watts to 0.2 watts in digital mode.
