Warning: Only use the recommended charger if possible. Other chargers may violate the warranty terms of the equipment
and results in danger. If the charging cable is delivered with the headset, connect the cable to a CCC-certified charger or
computer to charge the headset.
Charging the Battery
The headset is embedded with non-removable charging battery. Do not attempt to remove the battery from the headset;
otherwise, the headset may be damaged. If the headset is not used in a long time, keep it in a dry and well-ventilated place,
and charge the headset once every two months.
1. If the red indicator blinks every 8 seconds, the headset battery is low. If the headset continues to work, it may be
automatically powered off. At this time, you need to charge the headset by connecting the cable of the charger to the
charging port on the headset.
2. Connect the charger to an AC power socket.
3. The red indicator is on when the headset is being charged. If the charging is not started yet, disconnect the headset from
the power socket, and reconnect the headset again. It takes about 2 hours to fully charge the headset. After battery
charging is completed, the red indicator is off, and the blue indicator is on. At this time, you can disconnect the
charger from the power socket and headset.
4. A fully charged battery can provide about 11 hours of talk time, or 220 hours of standby time. The actual talk time and
standby time may vary with different cell phones, settings, use methods, and environment.
