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 can also charge the battery with a USB cable with power from a computer.
1 Connect the USB cable to a USB port of a computer and to your device.
2 When the battery is fully charged, disconnect the USB cable.
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.
Charging the device while listening to the radio may affect the quality of reception.
