Nokia BH-302 ユーザーズマニュアル

The headset 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 to a wall 

outlet. 

2. Connect the charger cable to the 

charger connector. The indicator 
light is on while 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 30 minutes.

3. When the battery is fully charged, 

the indicator light turns off. 
Disconnect the charger from the 
headset and the wall outlet.

The fully charged battery has power 
for up to 10 hours of talk-time or up to 
195 hours of standby time. However, 
the talk and standby times may vary 
when used with different mobile 
phones or other compatible Bluetooth 
devices, usage settings, usage styles, 
and environments.

When battery power is low, the 
indicator light flashes quickly.

To switch on, press and hold the 
multifunction key until the indicator 
light is displayed.

To switch off, press and hold the 
multifunction key until the indicator 
light briefly flashes several times and 
turns off.
