Setup
Battery Installation
- Unscrew the tail cap of the flashlight by turning it counter-clockwise.
- Insert 3 AAA batteries into the battery holder, ensuring correct polarity (+/-) as indicated inside the holder. Alternatively, insert one 3.7V rechargeable lithium-ion battery directly into the flashlight body with the positive (+) end facing the head of the flashlight.
- Screw the tail cap back on clockwise until it is securely tightened.
Operating Instructions
Power On/Off
Press the rubberized button located on the tail cap to turn the flashlight ON or OFF.
Changing Beam Modes
With the flashlight ON, lightly press the tail cap button repeatedly to cycle through the 5 available beam modes:
- High: Maximum brightness for powerful illumination.
- Medium: Moderate brightness for general use.
- Low: Reduced brightness for extended battery life or close-up tasks.
- S.O.S.: Flashes the Morse code signal for distress (three short, three long, three short).
- Strobe: Rapid flashing light for signaling or disorientation.
Adjusting Focus (Spotlight to Floodlight)
To adjust the beam focus, gently slide the head of the flashlight forward or backward. Sliding it forward will narrow the beam into a concentrated spotlight, while sliding it backward will widen it into a broad floodlight.
