5. Operating Instructions
The Arcchio Neru LED Wall Spot Light features an integrated motion detector for automatic operation.
- Automatic Operation: The light will automatically turn on when motion is detected within its sensor range and ambient light conditions are below a certain threshold (if applicable).
- Automatic Shut-off: After a period of no detected motion, the light will automatically turn off.
- Motion Sensor Settings: The luminaire may include adjustable settings for motion detection sensitivity and light duration via internal DIP switches. These are typically located on the back or inside the fixture. Refer to the detailed product diagram or consult a qualified electrician for adjustment.

6. Maintenance
- Cleaning: To clean the luminaire, ensure the power is off. Wipe the surface with a soft, dry, or slightly damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Light Source: The integrated LED light source is designed for long-term use and is not replaceable by the user. If the LED fails, the entire luminaire typically needs replacement.
- Inspection: Periodically inspect the luminaire for any signs of damage or loose connections. If any issues are found, disconnect power and consult a qualified electrician.
7. Troubleshooting
If you encounter issues with your Arcchio Neru LED Wall Spot Light, refer to the following common problems and solutions:
- Light does not turn on:
- Check if the main power supply is on.
- Verify that the wiring connections are secure and correct.
- Ensure the motion detector is not obstructed.
- Check the motion sensor settings (e.g., sensitivity, ambient light threshold) if adjustable.
- Light stays on continuously:
- Ensure there is no continuous motion within the sensor's detection range.
- Check the motion sensor's duration setting; it might be set to a long period.
- Verify that the ambient light sensor (if present) is not malfunctioning or covered, causing it to detect darkness constantly.
- Light flickers:
- Check for loose wiring connections.
- Ensure the voltage supply is stable and within the specified range.
If these steps do not resolve the issue, contact a qualified electrician or the retailer for further assistance.
