Maintenance
- Waterproof Seal: Always ensure the cap is tightened clockwise until it can no longer be screwed to maintain the IP68 waterproof rating. A loose cap will allow water to enter and damage the light.
- Battery Life: The lights can operate continuously for over 24 hours, though performance may vary with mode and brightness. Replace AAA batteries when the light output diminishes or the remote control becomes unresponsive.
- Long-term Submersion: For optimal longevity, avoid leaving the lights submerged for more than 10 hours continuously. Remove them from water after use, especially after events.
- Cleaning: Clean the lights with a soft, damp cloth. Do not use abrasive cleaners or solvents.
Troubleshooting
- Lights Not Turning On/Remote Unresponsive:
- Check if the AAA batteries in the LED lights are correctly installed and have sufficient charge. Replace if necessary.
- Ensure the remote control's CR2025 battery is functional. Replace if needed.
- Verify that there is a clear line of sight between the remote and the lights.
- Water Inside the Light:
- Immediately remove the light from water.
- Open the cap and remove the batteries.
- Allow the light and its components to dry completely before reassembling.
- Ensure the rubber O-ring is clean, undamaged, and properly seated before re-tightening the cap securely.
- Low Power Warning:
If the remote control does not work or the red lighting flashes slightly, this indicates low battery power in the submersible lights. Replace the AAA batteries to restore normal operation.
