3. Charging the battery of the Headset
Your headset has a built-in Li-ion battery which must be fully charged
before you can use the headset the first time.
It takes up to 4 hours to fully charge the battery the first time.
If the Red LED of the headset blinks during use, the battery is almost
empty. It will take about 2 hours to recharge the battery.
Charge by the travel charger:
Plug the travel charger into a free wall outlet and connect the Power
Plug to the DC input of the headset. The red indicator will light up.
When the battery is full, the red indicator will be off. Remove the
travel charger from your headset.
Charge by the USB charge cable:
Plug the USB charge cable in a free USB port of your computer and
connect the Power Plug to the DC input of the headset. The red
indicator will light up. When the battery is full, the red indicator will
be off. Remove the USB charge cable from your headset.
Note: When you charge your headset through the USB port of your
computer, the charging process can take longer, depending on
the supplied power of your USB port.
