9.7.2 Installation and set-up
General
The following points should be observed under all circumstances when
installing the laser receiver:

No obstacles (e.g. cables) may be located in front of the sensor;

Laser transmitters and laser receivers must always be "clearly
visible" to each other;
Ideally, install both so high that the rotating laser beam is able to
shine over the roof of the vehicle.

No reflective surfaces (e.g. windows, motor vehicle glazing) may be
located in the area of the laser beam;
To minimise the occurrence of reflections, it is advisable to cover
the laser transmitter except for the circular cut-out which is
actually required.

The laser transmitter's specified range must not be exceeded (note
environmental influences).
Working point
Commission a suitable laser transmitter
(wavelength between 600 and 1030 nm) at an
adequate height in accordance with its operating
instructions.
Position the mast, on which the laser receiver is mounted, vertically.
