Battery level indication
With the headlamp switched off, single click the switch to display the battery level for 3 seconds in different colors:
Green constant on: more than 80%
Green flashes: 50% – 80%
Blue constant on: 20% – 50%

Uncover the anti-dust cap and plug the Micro USB terminal of the charging cable into the charging port of the headlamp. Once charging is completed, be sure to remove the charging cable and replace the anti-dust cap. The max charging current is 700mA, and the charging time is about 1.5 hours. The indicator displays blue when charging, and turns green when fully charged. The headlamp can only be used on Med output when charging.

Warning: Avoid charging non-rechargeable batteries.

Intelligent Overheat Protection
The light will accumulate a lot of heat when used on Turbo output level for extended periods. When the light reaches a temperature of 65°C or above, the light will automatically downshift to High output to reduce temperature. Reset to Turbo if needed.

Low Voltage Downshift
When the voltage of the 16340 battery in use drops lower than 3.0V, the low voltage downshift function will be activated. In this state the headlamp cannot be used on Turbo output and will only cycle through High, Med and Low.

Extended Runtime
The headlamp will automatically step down by a few lumens after being used for an extended period on any of the High, Med or Low outputs, to extend runtime and to guarantee illumination outdoors.

Use as a flashlight
Remove the tail cap and the battery, then remove the headlamp from the holder. Re-insert the battery and screw back the tail cap.
