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.
Maintaining Your Phone's Peak Performance
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.
•
To ensure that the Hearing Aid Compatibility rating for your phone is
maintained, secondary transmitters such as Bluetooth and WLAN
components must be disabled during a call. For more information, refer to
“Turn Bluetooth On/Off” on page 100
•
If your phone is equipped with an external antenna, hold the phone with the
antenna raised, fully-extended and over your shoulder.
•
Do not hold, bend or twist the phone's antenna, if applicable.
•
Do not use the phone if the antenna is damaged.
•
If your phone is equipped with an internal antenna, obstructing the internal
antenna could inhibit call performance.
•
Speak directly into the phone's receiver.
