Obtaining Sufficient Dip Angle
Raise the scanner position so that there is a sufficient dip angle available between the line of sight from the
scanner to the obstacle and the horizontal line. By raising the dip angle 5°, it is possible to prevent mid- and
long-distance shadow zones. Don’t adjust the dip angle too high since the radar cannot detect objects below
the sight line.
Mounting Base
The scanner can be installed directly to a roof or other flat surface. You can also use a mounting bracket. Be
certain you keep the water drain tube clear. It is located at the bottom of the scanner unit.
NOTE:
If the mounting bracket or surface has a curvature of more than 2 mm, use spacers with the mounting bolts to prevent
stress on the scanner housing.
Do not mount on a
surface with an
edge that might trap
water.
