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.
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.
