Operations

ON/OFF
Tap the tail switch to turn on the light temporarily, fully press to turn ON/OFF the light.

Output Selection
Tap the tail switch first, then release and fast tap again in 1 second to cycle through High→Mid→Low→Strobe.
When the needed brightness level selected, fully press the switch to power the light constantly, and press again to turn off the light.

Note: The light will not memorize brightness level over 1 second after it is turned off. Each time it will activate at High brightness level.

Low-voltage Warning Function
When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level. When this happens in Low output mode, the flashlight blinks three times every five minutes to remind you to replace the battery. To ensure normal use, the flashlight will not turn off automatically and will work until the battery runs out completely.

Note: This only works on 18650 rechargeable Li-ion battery. When the voltage of 18650 battery is detected lower than 3V, low-voltage warning function will fail if the flashlight is turned on again.

Over-heat Protection
The light will accumulate a lot of heat when it is working at High brightness level. When it works at High for 5 minutes or above, the flashlight will automatically downshift into Mid output to prevent the light from overheating. Please reset if High output again is needed.
