Battery Use
The handheld uses special rechargeable
lithium batteries. The handheld can be charged
through a power adapter or by connecting to a
PC with a dedicated USB 2.0 line.
Charge and discharge:
A charged battery will discharge over a certain
period if it is not in use.
Precautions on Battery Use
For safety reasons, do not use any
damaged rechargeable batteries.
When you use the handheld near a
network base station, battery consumption
is low. Therefore, the call and standby
duration is largely affected by the signal
strength of the cellular network and
parameters set by the network operator.
The battery charge time depends on the
remaining battery capacity and the type of
the battery and charger. Rechargeable
batteries can be used repeatedly, but will
ultimately malfunction. When the used
time of a battery (call time and standby
time) declines significantly, consider
buying a new battery.
A fully charged battery will discharge if it is
not in use.
Use the designated battery and charger.
Cut off the power when the charger is not
in use. Do not connect the battery to the
charger for over a week. Overcharging will
shorten the service life of the battery.
Do not store the battery in places of
extreme temperatures; for example, in a
car in summer or winter; otherwise the
capacity and lifecycle of the battery will
degrade. Try to maintain a constant indoor
temperature for the battery. The handheld
may fail to work temporarily in an
environment that is either too hot or too
