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 91.
•
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.
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.
