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 on the headset. 
The red indicator light is displayed 
while charging. It may take a while 
before charging starts. If charging 
does not start, connect the charger 
again, and retry. Charging the 
battery fully may take up to 
2 hours.

the red 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 
240 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 and the 
headset beeps every 20 seconds.
