Charging Function

Connecting the Power Source: As illustrated, after uncapping the charging port cover, use the USB cable to connect an external power supply (e.g. a USB adapter or other USB charging devices) to the charging port to begin the charging process.

Charging Indication: During the charging process, the power indicator beside the primary light will be steadily glowing red. When the battery is fully charged, it will automatically cease the charging process and the power indicator will turn green.

Note:

1. The charging function is only available to charging the built-in Li-ion battery. When AAA batteries are inserted, it will not affect the charging process.
