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 15 minutes of 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 idle 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.
