- Screw the tail cap back on tightly.

The TC12 features a built-in Micro USB charging port, allowing for convenient charging without removing the battery.
- Locate the Micro USB port on the side of the flashlight head. It is protected by a rubber cover.
- Gently lift the rubber cover to expose the USB port.
- Connect the included USB charging cable to the flashlight's Micro USB port and the other end to a USB power source (e.g., computer, wall adapter, power bank).
- During charging, an indicator light will illuminate. The light will change color to indicate charging status (e.g., red for charging, blue for fully charged).
- Once charging is complete, disconnect the USB cable and firmly press the rubber cover back into place to ensure waterproof integrity.
5. Operation
The ThruNite TC12 features two switches: a tail switch for power ON/OFF and a side switch for mode selection.
5.1 Power ON/OFF
- To turn the flashlight ON or OFF, press the tail switch.
5.2 Mode Switching
While the flashlight is ON, press the side switch to cycle through the following modes: Firefly → Low → Medium → High → Turbo.
5.3 Strobe Mode
- While the flashlight is ON, press and hold the side switch for approximately 1 second to activate Strobe mode (12.5Hz).
- To exit Strobe mode and return to the previously used normal mode, press the side switch again.
6. Maintenance
- Cleaning: Clean the flashlight body and lens with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- O-rings: Periodically inspect the O-rings for wear and tear. Replace them with the provided spare O-rings if necessary to maintain the waterproof seal. Apply silicone grease to the O-rings to keep them supple.
- Threads: Keep the threads clean and lubricated to ensure smooth operation of the tail cap.
- Battery Care: If the flashlight will not be used for an extended period, remove the battery to prevent potential leakage. Store the battery in a cool, dry place.
- USB Port: Ensure the rubber cover for the USB port is securely closed when not charging to prevent dust and water ingress.
7. Troubleshooting
7.1 Flashlight Not Turning On
- Ensure the battery is inserted correctly with the positive (+) end facing the head.
- Check if the battery is fully charged. If not, charge it using the USB port.
- Tighten the tail cap and head of the flashlight firmly. Loose connections can prevent operation.
- Clean the battery contacts and flashlight threads with a clean cloth.
7.2 Intermittent Operation or Flickering
- This often indicates a low battery. Recharge the battery.
- Ensure all connections (tail cap, head) are tight.
- Clean battery contacts and threads.
7.3 Overheating
- The TC12 is equipped with Intelligent Temperature Control (ITC) Technology. If the flashlight reaches 80℃, it will automatically reduce its output to prevent damage and extend LED lifespan. This is normal operation.
- If the flashlight becomes excessively hot during normal use at lower modes, contact customer support.
8. Safety Information
- Do not shine the flashlight directly into eyes. The powerful beam can cause temporary vision impairment.
- Keep out of reach of children.
- Do not disassemble the flashlight head or modify the internal components, as this may void the warranty and cause damage.
- Use only recommended 18650 batteries.
- Ensure the USB port cover is sealed when not charging to maintain water resistance.
- Avoid exposing the flashlight to extreme temperatures or direct sunlight for prolonged periods.
