5.2 Initial Charging
Before first use, fully charge the battery.
- Locate the Micro-USB charging port on the battery itself.
- Connect the Micro-USB cable to the battery and the other end to a USB power source (e.g., computer, wall adapter).

6. Operation
6.1 Power On/Off
To turn the flashlight ON or OFF, press the tail switch firmly until it clicks.
6.2 Switching Modes
The N8F flashlight features 5 lighting modes: High, Medium, Low, Strobe, and SOS.
- With the flashlight ON, gently half-press the tail switch (without clicking) to cycle through the modes in the order: High → Medium → Low → Strobe → SOS.
- Release the switch to select the desired mode.

6.3 Adjustable Focus (Zoom)
The N8F allows you to adjust the beam from a wide flood to a narrow spot:
- To adjust the focus, slide the head of the flashlight forward or backward.
- Sliding the head forward will narrow the beam for a longer throw (spotlight).
- Sliding the head backward will widen the beam for broader area illumination (floodlight).


7. Maintenance

- For the lens, use a lens cleaning cloth to avoid scratches.

- Store the flashlight and battery in a cool, dry place.
- If storing for extended periods, remove the battery from the flashlight.
7.3 Water Resistance (IP65)
The N8F flashlight is rated IP65, meaning it is protected against dust ingress and low-pressure water jets from any direction. It is not designed for submersion.
- Ensure the tail cap is fully tightened to maintain water resistance.
- Regularly inspect the O-rings for wear and tear. Replace them with the provided spare O-ring if necessary.
