5.4 Timer Function
The built-in timer allows for automatic on/off cycles. Press the Timer Button (

Once a timer mode is selected, the light will automatically turn off after the set duration and then turn back on at the same time the next day, maintaining a consistent lighting schedule.
Note: The light's internal timer defaults to OFF if power is interrupted (e.g., by an external timer or power outage). It is recommended to use the built-in timer for consistent scheduling.
6. Maintenance
- Cleaning: Unplug the light before cleaning. Use a soft, dry cloth to wipe the light fixture. Do not use abrasive cleaners or immerse the light in water.
- Inspection: Regularly inspect the power cord and light fixture for any signs of damage. If damage is found, discontinue use and contact customer support.
- Water Contact: As the light is not waterproof, always ensure it is positioned to minimize exposure to splashing water.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power, loose connection, faulty power adapter. | Check if the power adapter is securely plugged into the outlet and the light. Test the outlet with another device. |
| Light modes or brightness not changing. | Controller malfunction, button not pressed correctly. | Ensure buttons are pressed firmly. Unplug and replug the light to reset the controller. |
| Timer function not working as expected. | Power interruption, incorrect timer setting. | Ensure the light is not connected to an external timer.
