6.4. Tips for Sensor Installation (fig. 10, 11 and 12)
Install the sensors inside the bumper. This protects the sensors from interference and enables them to work perfectly
under bad weather conditions.
Different vehicles have different widths so choose the right location to mount the sensors. Take care to install the
sensors with the head pointing in a horizontal direction. All sensors must be installed at the same height and at least
50cm above the ground (see fig. 10 below). Make sure the sensor is installed in a spot where no part of the vehicle
itself will be detected (see fig. 11 below).
Drill holes in the bumper and insert the sensors with the "UP" arrow pointing upwards. Make sure the central axis of
the sensor is perpendicular to the bumper surface.
Horizontal and vertical positioning: see fig. 12 below.
