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.
• 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.
• Avoid exposing your phone and accessories to rain or
liquid spills. If your phone does get wet, immediately turn
the power off and remove the battery. If it is inoperable,
call Customer Care for service.

Battery Standby and Talk Time

features selected, frequency of calls, and voice, data,

Battery Precautions
• Avoid dropping the cell phone. Dropping it, especially on a
hard surface, can potentially cause damage to the phone
and battery. If you suspect damage to the phone or
battery, take it to a service center for inspection.
• Never use any charger or battery that is damaged in any
way.
