5. Maintenance
- Cleaning: Regularly wipe the solar panel and motion sensor window with a soft, damp cloth to ensure optimal performance. Avoid abrasive cleaners.
- Battery Care: If the alarm's performance diminishes (e.g., weaker sound or light), it may indicate a low battery. Recharge the device fully using either solar power or the USB cable. The device uses internal rechargeable Lithium-Ion batteries.
- Winter Use: While IP65 waterproof, prolonged periods of heavy snow or ice might reduce solar charging efficiency. Consider USB charging during such conditions if needed.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm not activating (no sound/light) | Low battery Sensor obstructed Incorrect mode selected | Recharge the device via solar or USB. Clear any obstructions from the sensor window. Ensure the ON/OFF switch is on and the correct operating mode is selected. |
