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.
