Operations
This light has 3 main levels (High, Medium, and Low). Each main level can be configured to one of its two sub-levels. The second sub-level of each main level can be further configured to different brightness levels or strobes.

Press and hold to cycle from Low to High, release to set. When press and hold, the light always cycle from Low to High regardless which level you are currently in.
Double click to toggle and select between the two sub-levels for that main level. Sub-level selections (except the strobe) for the 3 main levels are memorized after the light is turned off and through battery changes.
The second sub-level of each main levels can be configured after 6 double clicks. Double click (startng with the 7th) to cycle and select different brightness levels or strobes. Short click to turn off the light when finishing configurations. The selections for the second sub-level are memorized after the light is turned off and through battery changes.
This light uses the LEDs to indicate the estimated remaining battery capacity by flashing 1 to 4 times. To start the battery indicator, short-click 4 times without pause from OFF.
