1 Connect the charger to a wall outlet.
2 Connect the charger to the device.
3 When the device indicates a full
charge, disconnect the charger from
the device, then from the wall outlet.
You do not need to charge the battery for
a specific length of time, and you can use
the device while it charges. If the battery
is completely without charge, it may take
several minutes before the charging
indicator appears on the display or before
any calls can be made.

Antenna

Your device may have internal and
external antennas. Avoid touching the
antenna area unnecessarily while the
antenna is transmitting or receiving.
Contact with antennas affects the
communication quality and may cause a
higher power level during operation and
may reduce the battery life.
The figure shows the antenna area
marked in grey.

Headset

Warning:
When you use the headset, your ability to
hear outside sounds may be affected. Do
not use the headset where it can
endanger your safety.
