Check the model number of any charger before use with this device. This device is intended 
for use when supplied with power from an AC-3 or AC-4 charger.

Warning: Use only batteries, chargers, and enhancements approved by Nokia for 
use with this particular model. The use of any other types may invalidate any 
approval or warranty, and may be dangerous.

For availability of approved enhancements, please check with your dealer. When you 
disconnect the power cord of any enhancement, grasp and pull the plug, not the cord.

1. Connect the charger to a standard wall outlet.

2. Insert the charger plug into the jack on the bottom of the phone.

If the battery is completely discharged, it may take a few minutes 
before the charging indicator appears on the display or before any 
calls can be made.

The charging time depends on the charger used. Charging a BL-4C 
battery with the AC-3 charger takes approximately 2 hours and 20 minutes while the phone is 
in the standby mode.
