MDS-1R/8R/9R/10R Installation
d Obtaining sufficient dip angle
Raise the scanner position so that there is a sufficient dip angle
θ available between the
line of sight from the scanner to the obstacle and the horizontal line. By raising the dip angle
above 5
°, it is possible to prevent mid- and long-distance shadow zones. The radar cannot
detect objects below the line of sight.

3.2 Installing Scanner Unit
Use a mounting base such as the ones shown in Fig. 3.3, or you can install the scanner
directly to a roof or other flat surface. Be certain you keep the water drain tube clear. It's
located at the bottom of the scanner unit.
Note : If the mounting bracket or surface has a curvature of more than 2mm, use spacers with the mounting
bolts to prevent stress on the scanner housing.
