If you're inside a building, being near a window may give you better
reception.
Understanding the Power Save Feature
If your phone is unable to find a signal after 15 minutes of searching, a
Power Save feature is automatically activated. If your phone is active, it
periodically rechecks service availability or you can check it yourself by
pressing any key.
Anytime the Power Save feature is activated, a message displays on the
screen. When a signal is found, your phone returns to standby 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.

Place the mobile phone's acoustic output next to your ear for
proper orientation.

Do not tamper or alter the phone's antenna.

Don't use the phone if the antenna is damaged.

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

Never use any charger or battery that is damaged in any way.

Use the battery only for its intended purpose.

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.
