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.
• Battery charging time depends on the
remaining battery charge and the type of
battery and charger used. The battery can
be charged and discharged hundreds of
times, but it will gradually wear out. When
the operation time (talk time and standby
time) is noticeably shorter than normal, it is
time to buy a new battery.
• If left unused, a fully charged battery will
discharge itself over time.
