Troubleshooting

Malfunction Cause Remedy	Cause	Remedy

The light will not come on

The lamp is on without any identifiable movement

| The sensor is not mounted for reliably detecting movement| Securely mount enclosure

Movement occurred, but not identified by the sensor (Movement behind wall, movement of small object in immediate lamp vicinity etc.)

| 1. Reduce sensitivity.

2. Check the movement behind walls to avoid facilities such as water pipe, fan, which may mis-trigger the sensor.

The lamp will not work despite movement| Rapid movements are being suppressed to minimize malfunctioning or the detection radius is too small.| ****

Check detection area setting
