3. Mounting the Flashlight

Operating Instructions
1. Power On/Off and Mode Selection
The flashlight offers two primary methods for operation: using the standard push-button tail cap or the coiled tactical pressure switch.
- Using the Push-Button Tail Cap:
- Press the button firmly to turn the flashlight ON or OFF.
- With the flashlight ON, lightly press the button (without clicking) to cycle through the five modes: High, Mid, Low, Strobe, and SOS. A full click will turn the flashlight off.
- Using the Coiled Tactical Pressure Switch:
- Replace the standard tail cap with the pressure switch tail cap.
- When the pressure switch is connected, the flashlight operates in a single, brightest mode.
- Press and hold the pressure pad for momentary on. Release to turn off.
- Some pressure switches may have a constant on/off button in addition to the momentary pad. Refer to your specific pressure switch for details.

2. Adjusting the Beam (Zoom Function)
The flashlight features an adjustable head to change the beam from a wide floodlight to a focused spotlight.
- To adjust the beam, gently slide the head of the flashlight forward or backward.
- Sliding the head forward will narrow the beam into a focused spotlight for long-range illumination.
- Sliding the head backward will widen the beam into a floodlight for broader area illumination.

- The flashlight will begin charging your device. Monitor your device's charging indicator.
Maintenance
- Cleaning: Wipe the flashlight body with a clean, soft cloth. For stubborn dirt, a slightly damp cloth can be used. Do not use abrasive cleaners or solvents.
- Lubrication: Periodically apply a thin layer of silicone grease to the O-rings and screw threads to maintain water resistance and smooth operation.
- Battery Care: If the flashlight will not be used for an extended period, remove the battery to prevent leakage and damage. Store batteries in a cool, dry place.
- Storage: Store the flashlight in a cool, dry environment away from direct sunlight and extreme temperatures.
