Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | Battery is depleted. Incorrect mode selected. Sensor obstructed. | Charge the battery. Press the button to cycle through modes (Constant-on, Motion Sensor). Ensure sensor is clear. |
| Light does not activate in Motion Sensor Mode. | Ambient light is too bright. Motion is outside detection range. Battery is low. | Motion sensor mode only works in low-light conditions. Ensure motion occurs within 3 meters and 120° angle. Charge the battery. |
| Light falls off mounting surface. | Adhesive is weak or surface was not clean. Magnetic attachment is weak. | Clean surface thoroughly and reapply iron sheet with new strong adhesive tape. Ensure light is properly aligned with the magnetic plate. |
| Brightness is too low/high. | Brightness setting needs adjustment. | Press and hold the button for 3 seconds to adjust brightness. |
