Charge the battery
Before using the headset, you must charge the battery.
When you unplug a charger, hold and pull the plug, not the cord.
1 Connect the charger to a wall outlet.
2 Connect the charger cable to the charger connector on the headset. The red indicator
light turns green when the battery is fully charged.
3 Disconnect the charger from the headset, then from the wall outlet.
The fully charged battery has power for up to 8 hours of talk time or music playing time,
or up to 35 hours of standby time with active noise cancellation (ANC) activated. To
increase standby time, deactivate ANC if you are not using the headset. When ANC is not
activated, the standby time is up to 240 hours.
After 15 minutes of charging, the battery has power for over 4 hours and 30 minutes of
talk or music playing time.
When the battery charge is low, the headset beeps every 5 minutes and the red indicator
light flashes.
If you activate ANC without switching the headset on, when the battery charge is low,
the headset doesn't beep and the red indicator light stays on.
Check the battery charge
With your headset connected to your mobile device, press . A green light indicates a
sufficient charge level. If the light is yellow, you may need to recharge the battery soon.
If the light is red, recharge the battery.
