Nokia C3-00 - Manual (Page 10)

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 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.
