Charging
Turn off the flashlight and connect the USB Type-C end of the charging cable. The indicator displays red while charging and turns green when full. While charging, only Moonlight through Med outputs are available; Red light, Green laser, Strobe, and Turbo cannot be used while charging. Normal charging time is about 2.5 hours.
Battery Level Indication
With the light off, single click the neck-mounted switch to check battery level (lasts 3 seconds). Green on: saturated 100–85%. Green flashes: sufficient 85–50%. Red on: poor 50–25%. Red flashes: critical 25–1%.
Intelligent Overheat Protection
At 60°C/140°F or above, the flashlight automatically steps down output to reduce temperature, gradually recalling the preset output level as it cools.
Low-Voltage Warning
Below the preset voltage level, the flashlight downshifts until Moonlight is reached, then blinks red continuously until the battery is depleted.
