Operation Instructions:

In unlocked status, press and hold the switch for 0.5 seconds to turn ON/OFF the light.

Output Selection
With the light on, single click the switch to circle through Turbo?Eco?Low?Med?High. (The factory default output level is Turbo).

Flash Mode
In unlocked status, press and hold the switch for 1.2 seconds to enter Strobe. Single click the switch to circle through Stroke?SOS. Press and hold the switch for 1.2 seconds once again to turn back to previous General output level.

Spot and Floodlight Adjustment
Rotate the focusing ring to regulate between spotlight and floodlight. Clockwise regulate gradually to floodlight. Counterclockwise regulate gradually to spotlight. (The factory default is between spot- and floodlight. The focusing ring could be a little tight for first rotating.)

Lockout Function

  • Lock
    With the light turned off, continuous single clicking the switch twice within 0.5 seconds, the light will blink twice on Low and then switch off to indicate locked status.
  • Unlock
    With the light locked, continuous single clicking the switch twice within 0.5 seconds. The light will be unlocked and activated on last used brightness.
  • Locked Status
    In locked status, single clicking or pressing the switch will activate 2 blinks and then switch off to indicate locked status.

Intelligent Memory Circuit
The light memorizes the last selected brightness level on General mode. When turned on again the previously used brightness level will be recalled.

Overheat Protection
The light will accumulate a lot of heat when used on Turbo output level for extended periods. When a temperature of 55°C or above is reached, the light will automatically step down by a few lumens to reduce temperature. When the temperature is reduced, the output will gradually return to Turbo output level.

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

Battery Replacement
Unscrew the tail cap to insert the battery with the polarity markings accordingly to the signs in the flashlight, and then screw the tail cap back on.
