- Water Resistance: This flashlight is splash-proof only (IPX65 rated). Do not submerge it in water.
- Temperature: Operate within the specified temperature range of -25°C to 50°C.

4. Setup
- Battery Installation: Unscrew the tail cap of the flashlight. Insert one (1) 18650 rechargeable battery with the positive (+) end facing towards the head of the flashlight. Screw the tail cap back on securely.
- Scope Mount Attachment: If using the included scope mount, slide the flashlight into the mount and secure it using the provided screws. Attach the mount to your night vision scope or desired fixture.
- Pressure Switch Connection: Replace the standard tail cap with the pressure switch if desired. Ensure it is screwed on tightly to maintain connection.
5. Operating Instructions
- On/Off Operation: Hard press the tail switch (a complete press until it clicks) to activate the flashlight. Hard press the tail switch again (a complete press until it clicks) to turn the light off.
- Mode Selection: With the light on, gently press (a half-way press) the tail switch to cycle through the different illumination modes: Low → Mid → High. The flashlight features mode memory, meaning it will turn on to the last setting it was operated on.
- Adjustable Focus: The flashlight features a rotary focusing system with a 67mm aspherical lens. Rotate the head of the flashlight to adjust the beam from a tight spotlight for long-range illumination to a wider flood effect.
- Quick Dimmer Switch (if applicable): If your model includes a quick dimmer switch, press the switch when the light is ON, then twist the tail switch to adjust the brightness from 5% to 95%.
