Charging the headset
The headset contains a lithium ion rechargeable battery. Charge the headset using the supplied micro-USB cable.
Hint
If charging starts while the headset is turned on, the headset will turn off automatically.
Note
If the headset is not used for a long time, the battery may be quickly depleted, however, after a few recharges, the battery life will
improve.
If you store the headset for a long time, charge the battery to its full capacity once every 6 months to avoid over discharge.
If the headset is not used for a long time, it may take longer to charge the battery.
Open the micro-USB port cover.

computer.

After charging is complete, disconnect the micro-USB cable, then close the micro-USB port cover securely to
prevent water or dusts being mixed into the headset.
