Operating Instructions
QuickClick System
The ML300L features the QuickClick system, allowing users to easily switch between various lighting modes by rapidly clicking the power button. The default mode (General) provides three power settings:
- One Click: Full Power (168 lumens)
- Two Clicks: Low Power
- Three Clicks: Eco Mode (58 lumens) for extended runtime
Adjustable Focus
The flashlight's beam can be adjusted from a narrow spotlight to a wide floodlight. To adjust the focus, simply rotate the head of the flashlight less than a quarter turn. This allows for quick transitions between long-range visibility and broader area illumination.
Activity-Based Function Sets
The ML300L offers four customizable function sets, each tailored for specific activities. You can program the flashlight to respond differently to clicks based on your needs:
- General (Default): Full Power, Low Power, Eco Mode.
- Outdoor: Full Power, Low Power, Strobe.
- Law Enforcement: Momentary, Full Power, Eco Mode.
- Tactical: Momentary, Full Power, Strobe.
To change the function set:
- Unscrew the tail cap slightly (less than 1/4 turn) until the flashlight does not turn on.
- While holding down the power button, screw the tail cap back on completely.
- Continue holding the button. The flashlight will blink to indicate the current function set (1 blink for General, 2 for Outdoor, etc.). Release the button during the pause after the desired number of blinks to select that function set.

Cleaning
