7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | Dead or incorrectly installed batteries. Remote battery dead. | Replace AAA batteries in the light, ensuring correct polarity. Replace CR2032 battery in the remote. Ensure remote is pointed directly at the light. |
| Light flickers or dims. | Low battery power. | Replace AAA batteries in the light. |
| Water inside the light. | Cap not tightened sufficiently. | Remove light from water immediately. Open, dry thoroughly, and replace batteries if corroded. Ensure cap is twisted clockwise until it cannot turn any further before next use. |
| Remote not responding. | Remote battery dead or out of range. Obstruction between remote and light. | Replace CR2032 battery. Ensure remote is within 10m range and has a clear line of sight to the light. |
8. Important Warnings

- Usage: These lights are intended for special occasion lighting and temporary decorative use. They are not designed for permanent submersion.
- Battery Safety:
- Do not mix old and new batteries.
