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.

For the best care of your phone, only authorized personnel should
service your phone and accessories. Faulty service may void the
warranty.
There are several simple guidelines to operating your phone properly
and maintaining safe, satisfactory service.

maintained, secondary transmitters such as Bluetooth and WLAN
components must be disabled during a call. For more information, refer to
