starts. If charging does not start, 
disconnect the charger, plug it in 
again, and retry. Charging the 
battery fully may take up to 1 hour 
and 30 minutes.

the indicator light turns to green. 
Disconnect the charger from the 
headset and the wall outlet.
The fully charged battery has power 
for up to 6 hours and 30 minutes of 
talk-time or up to 150 hours of 
standby time. However, the talk and

When battery power falls low, the 
headset beeps and the red indicator 
light starts to flash.
