Adjust the DUSK control setting anti-clockwise
to lower the level of ambient light required
for activation.
The PIR may be poorly located
(See section 4. Selecting a location)
and re-locate the unit.
The PIR detectors are influenced by
climatic conditions. The colder the ambient
temperature, the more effective the sensor
will be.
You may need to make seasonal adjustments
to the detector head position to ensure trouble-
free operation all year round.
