6.3. Motion Sensor Mode (Auto Mode)
In Auto Mode, the wall light intelligently responds to its environment:
- The light will remain off in well-lit conditions to conserve energy.
- When the environment is dark, the motion sensor activates.
- Upon detecting human movement within 3.5 meters (11 feet) and a 120° wide-angle range, the light will automatically turn on.
- After approximately 30 seconds of no further human activity, the light will automatically turn off.

7. Maintenance
- Cleaning: Use a soft, dry cloth to wipe the surface of the light. Avoid abrasive cleaners or solvents.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Recharge when the light output appears dim.
- Storage: If storing the light for an extended period, ensure it is fully charged and store in a cool, dry place. Recharge every few months to maintain battery health.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on in Auto Mode. | Environment is too bright; battery is low; motion sensor obstructed. | Ensure the environment is dark enough for Auto Mode; charge the battery; clear any obstructions from the motion sensor. |
| Remote control is not working. | Remote batteries are dead or incorrectly inserted; remote is too far from the light. | Replace AAA batteries in the remote; ensure correct battery polarity; operate the remote within 6-7 meters of the light. |
| Light turns off too quickly/slowly. | Timer setting is active. | Adjust or deactivate the timer setting using the remote control. |
