Charge the battery
Your battery has been partially charged at the factory. If the
device indicates a low charge, do the following:
1. Connect the charger to a wall outlet.
2. Connect the charger to the device. The charging port is
behind the black cover.
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 is charging. If the
battery is completely discharged, it may take several minutes
before the charging indicator appears on the display or
before any calls can be made.
Tip: Disconnect the charger from the wall outlet when
the charger is not in use. A charger that is connected
to the outlet consumes power even when it is not
connected to the device.
