Safety Information
To ensure safe operation and prevent damage, please adhere to the following safety guidelines:

- While the string lights are waterproof for outdoor use, the power adapter should be protected from direct exposure to rain, snow, or standing water. Ensure it is placed in a dry, sheltered location.

- Keep the lights away from open flames, heat sources, and flammable materials.
- Unplug the lights from the power outlet when not in use or before performing any maintenance.
- Do not hang objects from the string lights or place them in a way that could cause damage to the wiring.

Maintenance
Proper maintenance ensures the longevity of your string lights:
- Cleaning: Gently wipe the lights with a soft, dry cloth to remove dust or debris. Do not use harsh chemicals, solvents, or abrasive cleaners, as these can damage the wiring or LED bulbs.
- Storage: When not in use, especially during off-seasons, carefully coil the string lights to prevent tangling. Store them in a cool, dry place, away from direct sunlight, extreme temperatures, and moisture.
- Inspection: Periodically inspect the entire length of the string lights, including the wiring, bulbs, and power adapter, for any signs of damage, fraying, or loose connections. Discontinue use immediately if any damage is found and contact support.
Troubleshooting
If you encounter any issues with your string lights, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights not turning on | No power to the outlet; Loose connection; Faulty adapter | Ensure the power adapter is securely plugged into a working electrical outlet. Check the connection between the string lights and the adapter. Try a different outlet. |
| Lights flickering or dim | Loose connection; Unstable power source | Check all connections for tightness. Ensure the power source is stable and not overloaded. |
| Lighting modes not changing | Button not pressed correctly; Temporary glitch | Press the mode button on the adapter firmly. Unplug the adapter from the outlet, wait a few seconds, and then plug it back in to reset. |
