- Duration: Once activated, the light will remain on for 30 seconds. If motion is continuously detected, the light will stay on until motion ceases for 30 seconds.


Maintenance
- Battery Replacement: When the light output diminishes or the unit stops activating, it is time to replace the batteries. Follow the battery installation steps in the Setup section.
- Cleaning: Periodically wipe the lens and motion sensor with a soft, damp cloth to ensure optimal performance. Do not use abrasive cleaners or solvents.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | 1. Insufficient darkness. 2. Dead or incorrectly installed batteries. 3. Motion sensor obstructed. | 1. Test in a darker environment. 2. Replace batteries, ensuring correct polarity. 3. Clear any obstructions from the sensor's view. |
| Light stays on constantly or triggers repeatedly. | 1. Continuous motion in sensor range. 2. Sensor sensitivity too high (if adjustable, though this model is fixed). 3. Environmental factors (e.g., heat sources, strong winds moving objects). | 1. Ensure no constant motion is within the detection zone. 2. Reposition the spotlight to avoid areas with constant activity or environmental disturbances. 3. Check for heat sources or moving objects (e.g., tree branches) that might be triggering the sensor. |
| Light is dim. | Low battery power. | Replace all batteries with new C-cell batteries. |
