Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | Battery is depleted. Incorrect sensor mode. | Charge the light fully. Check the sensor mode (S2 button) and ensure it's set to 'Always ON' or a suitable motion sensor mode. |
| Motion sensor is not working. | Incorrect sensor mode. Obstruction of sensor. | Ensure the light is in 'All-Day Motion Sensor' or 'Light & Motion Sensor' mode. Clear any obstructions from the sensor lens. |
| Light turns off too quickly. | Standard operation. | The light is designed to turn off after 20 seconds of no detected motion. If continuous light is needed, switch to 'Always ON' mode. |
| Short battery life. | Frequent activation. Battery degradation over time. | Reduce frequency of activation by using 'Light & Motion Sensor' mode in areas with sufficient daytime light. Ensure the light is fully charged. Battery capacity may naturally decrease after extended use (e.g., 1 year or more). |
| Light is not charging. | Faulty cable or power source. Damaged charging port. | Try a different USB cable and power source. Inspect the charging port for any visible damage. If the issue persists, contact customer support. |
