Warning: Use only batteries and chargers approved by Nokia for use 
with this particular enhancement. 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.
■ Charge the battery
This device has an internal, nonremovable, rechargeable battery. Do not 
attempt to remove the battery from the device as you may damage the 
device.
1. Connect the charger cable to the headset.
2. Connect the charger to a wall outlet. The red 
indicator light is displayed during charging. It 
may take a while before charging starts. If 
charging does not start, disconnect the 
charger, plug it in again, and retry. Charging 
the battery fully may take up to 2 hours.
Ensure that you do not accidentally insert the 
earloop into the charger connector.
3. When the battery is fully charged, the red 
indicator light turns off. Disconnect the charger 
from the wall outlet and the headset.
The fully charged battery has power for up to 6 hours of talk-time or up to 
160 hours of standby time. However, the talk and standby times may vary
