2) Simply turn the cover anticlockwise to remove the wall-lens cover from the detector. Once
the wall-lens cover is removed, reload the detector with ceiling-lens cover and turn it
clockwise, ensure the mark on the cover is pointing towards and aligned with the mark on the
detector.
3) To detect movements with detection coverage up to 360 degrees, simply reload the
ceiling-lens cover without shading cap. No movements can be detected if the detector is
reloaded with a shading cap which maintains 12 lens segments.
Safety Notice
Don't make the device directly to the window/fan/air-conditioner or sunlight.
Do not install the device above or facing any source of heat directly, such as fires, radiators,
boilers, etc.
Confirm the device is positioned in place where the light source detected by the detector is
consistent with actual ambient illumination. Do not locate the detector in shadowy place.
Where possible, mount the detector so that the logical path of an intruder would cut across
the fan pattern rather than directly towards the detector.
In order to obtain the best results, please put the detector directly facing the entrance.
