2. In order to achieve POWER & ECO modes, the TK18 Cu must be powered by 18650 battery that can produce at least 10 Amps of current. There will only ECO mode when using the 18650 battery current < 10 Amps or 2xCR123 batteries.

3. Unauthorized disassembly may damage the flashlight and void the warranty.

4. It is normal if the surface heat is increased during use due to the excellent thermal conductivity technology. It is suggested to use in a well ventilated area with ambient temperature.

5. Caution hot when using continuously for a long time. Do not put it on flammable materials for a long time, any fire or any safety problems caused by this will not be related to the manufacturer and distributors.

6. Please check and replace the O-ring regularly to maintain the waterproof rating.

7. Please check and lubricate the threads regularly with professional lubricant.

8. Clean the contact surfaces regularly to keep the flashlight normal operation. If irregular strobe or failure to turn-on occurs, the contact surfaces may be dirty and requires cleaning by using alcohol cotton swabs.
