Important usage
information
Signal strength
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.
Understand 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.
