4. Setup
4.1 Initial Charging
- Locate the USB-C charging port on the flashlight.
- Connect the provided USB-C cable to the flashlight and a compatible USB power source (e.g., wall adapter, computer, power bank).
- The battery indicator lights will illuminate to show charging progress. All lights will be solid when fully charged.
4.2 Attaching the Wrist Strap
Thread the thin loop of the wrist strap through the small hole at the tail cap of the flashlight. Secure the strap by passing the larger end through the looped end and pulling it tight.
5. Operation
5.1 White Light Operation
- Press the Power Button (usually marked with a power symbol) once to turn on the white light in High mode. The battery indicator lights will briefly show the current charge level.
- Subsequent presses of the Power Button will cycle through the white light modes: High → Medium → Low → Strobe → SOS → Off.
- To turn off the white light directly from any mode, press and hold the Power Button for approximately 2 seconds.
5.2 UV Light Operation
- Press the UV Light Button (usually marked with a light bulb or UV symbol) once to turn on the UV black light.
- Press the UV Light Button again to turn off the UV light.
5.3 Adjustable Focus (Zoom Function)
To adjust the beam focus, gently slide the head of the flashlight forward or backward. Sliding it forward will narrow the beam for a focused spotlight, while sliding it backward will widen the beam for a broader floodlight.

5.4 Battery Indicator
The blue LED lights on the side of the flashlight indicate the battery charge level. Typically, four lights indicate a full charge, and the number of illuminated lights decreases as the battery drains.

6. Maintenance
6.1 Cleaning
Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Keep the lens clean for optimal light output.
6.2 Storage
Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, charge the battery periodically to maintain its health.
6.3 Battery Care
To prolong battery life, avoid fully discharging the flashlight frequently. Charge the battery when the indicator shows low power.
7. Troubleshooting
