Operating Instructions:

Remarks:
1. Memory function stores the general mode last used (Medium or High).
2. While light is turn off, quickly 4 clicks (Quadruple click) will lock-out the flashlight;
    While light is in lock-out, quickly 4 clicks (Quadruple click) again will unlock.
3. When using AAA battery, ECO mode have 6 lower brightness levels (0.1-15 lumens) to choose from. (Ratio error: ±20% output, while using different AAA battery).
    When using 10440 battery, ECO mode have 5 lower brightness levels (5-40 lumens) to choose from (Ratio error: ±10% output, while using different 10440 battery).
4. While the battery is fully charged, double click to Turbo, its brightness will be stepdown time by time.
    While the battery is lower, double click to Turbo, light will be flashed and then stepdown direct to ECO brightness, or even turn the light off.
    While the battery is lower, single click to general mode, 'Mid' and 'High' have similar output or light flashed and then stepdown direct to ECO brightness or even turn the light off.
