5. Maintenance
- Cleaning: Clean the flashlight body and lens with a soft, damp cloth. Avoid abrasive materials.
- O-rings: Periodically check and lubricate the O-rings to maintain the IP68 waterproof rating. Replace O-rings if damaged.
- Battery Care: Store the battery in a cool, dry area with low temperature for long-term storage.
- Impact Resistance: The flashlight is 1.5-meter impact-resistant. Avoid dropping it from excessive heights.
- Water Resistance: The flashlight has an IP68 rating, meaning it is dustproof and submersible up to 2 meters for 30 minutes. Ensure the tail cap is securely tightened before exposure to water.

6. Troubleshooting
- Flashlight not turning on: Ensure the battery is correctly inserted and fully charged. Remove the insulating film if it's the first use.
- Dim or flickering light: Check battery charge level. If using an AA battery, ensure it is fresh. Clean battery contacts if dirty.
- Overheating: The K1 may reduce output to prevent overheating during prolonged high-mode use. This is normal. Allow it to cool down.
- Laser/UV not working: Ensure the rotary switch is correctly aligned with the desired mode. Check battery level.
