Operating Instructions
Power On/Off
- To turn the flashlight ON, press the power switch button once.
- To turn the flashlight OFF, press and hold the power switch button for approximately 2 seconds, or cycle through all modes until it turns off.
Changing Lighting Modes
The flashlight features multiple lighting modes for various situations.

Image: A visual representation of the five lighting modes: High, Medium, Low, SOS, and Strobe. The image also highlights the "Smooth Current System" for gradual brightness transitions.
With the flashlight ON, press the power switch button repeatedly to cycle through the following modes:
- High: Maximum brightness for powerful illumination.
- Medium: Balanced brightness for general use.
- Low: Reduced brightness for extended runtime or close-range tasks.
- SOS: Flashes the international Morse code signal for distress.
- Strobe: Rapid, disorienting flashes for self-defense or signaling.
The flashlight's smooth current system ensures gradual brightness transitions, protecting your eyes and the flashlight components.
Adjustable Focus (Zoom Function)
The flashlight head can be extended or retracted to adjust the beam focus.

Image: Demonstrates the adjustable focus feature. "Zoom In" shows the head retracted for a wide-field floodlight, illuminating a large area (e.g., 2160 sq.ft). "Zoom Out" shows the head extended for a long-range spotlight, reaching up to 3937ft.
- To achieve a wide-field floodlight, push the head of the flashlight inwards (zoom in). This is ideal for illuminating a large area.
- To achieve a long-range spotlight, pull the head of the flashlight outwards (zoom out). This concentrates the beam for distant illumination.
Maintenance
Cleaning
- Wipe the flashlight body with a soft, damp cloth.
- Do not use abrasive cleaners or solvents, as they may damage the finish.
- Keep the lens clean for optimal light output. Use a lens cleaning cloth if necessary.
Storage
- Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures.
- If storing for an extended period, it is recommended to charge the battery every 3-6 months to maintain its lifespan.
