Install this device at a distance of at least A (m) (given below) away from reflective surfaces
such as metal walls, floors, ceilings, workpieces, covers, panels or glass surfaces.

If there exists a reflective surface in the place where this device is to be installed,
make sure to install this device so that reflected light from the reflective surface
does not enter into the receiver, or take countermeasures such as painting,
masking, roughening, or changing the material of the reflective surface, etc. Failure
to do so may cause the sensor not to detect, resulting in death or serious injury.

Note:The effective aperture angle for this device is ±2.5° (when L > 3m) as required by IEC 61496-2. However,
install this device away from reflective surfaces considering an effective aperture angle of ±3° to take
care of beam misalignment, etc., during installation.
