Battery charging
The unit’s battery must be recharged before use.
The accessory micro-USB cable must be used for recharging the unit’s battery.
Connect the appropriate connector on the accessory micro-USB cable to the micro-USB port on the headphones, and the
USB plug on the other end to a USB port on a computer.
When recharging begins, the LED indicator on the headphones will light red.
Full recharging requires about three hours; when recharging is completed, the LED indicator will turn off.
When the battery’s charge is approaching depletion, a beep sound will be heard in the headphones at one-minute
intervals.
Note
Battery recharging time and usable battery time may vary depending on ambient temperature and frequency of use.
Do not place metal objects near the headphones’ charging contacts, since dangerous electrical shorts or abnormal
heating may result.
Please don’t attempt to change the rechargeable lithium battery that should last the lifetime of the device.
Please don’t dispose used batteries/electronics with ordinary solid waste, since they contain toxic substances.
Please turn off your headset after your usage to get a longer battery life.
