Battery Installation

Unscrew the tail cap to insert 1*AA or 1* 14500 battery with the anode side (+)towards the head, then screw the tail cap back on.

Power indicator

The indicator in the side switch shows the power status for 5 seconds after turning the HD12 on.

Green =remaining battery power is good (more than 30%)

Red = remaining battery power is poor (10%- 30%).

Flashing Red = critical power.

Low Voltage Protection: lf the Ll-lON battery's voltage is lower than 2.7VHD12 will turn off automatically to avoid battery damage by over-discharge

Charging

The HD12 has a USB-C port for convenient recharging of its battery. While charging the LED power indicator flashes red. Once finished the indicator will turn green to indicate a full battery. While Reverse charging, once the indicator flashes red means poor power and stops reverse charging automatically. (lf used the AA battery, the LED power indicator will flashing alternately between green and red)
