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
“Activation”
on page 145.
•
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.
•
Never use any charger or battery that is damaged in any way.
•
Do not modify or remanufacture the battery as this could result in
serious safety hazards.
•
If you use the phone near the network's base station, it uses less
power; talk and standby time are greatly affected by the signal
strength on the cellular network and the parameters set by the
network operator.
•
Follow battery usage, storage and charging guidelines found in the
user’s guide.
