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.
• 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.
• 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 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.
Availability of Various Features/Ring Tones
Many services and features are network dependent and may require additional
subscription and/or usage charges. Not all features are available for purchase or
use in all areas. Downloadable Ring Tones may be available at an additional cost.
Other conditions and restrictions may apply. See your service provider for additional
information.
Battery Standby and Talk Time
Standby and talk times will vary depending on phone usage patterns and conditions.
Battery power consumption depends on factors such as network configuration,
signal strength, operating temperature, features selected, frequency of calls, and
voice, data, and other application usage patterns.
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.
