Installation
Installation Modes 3.1
Based on the vehicle movement direction, three installation modes are available: Approaching
(detects head of vehicles), receding (detects tail of vehicles), and both directions (detects either
head or tail, depending on the vehicle movement direction).
The Radar can either be installed right above the lane, or at the side of a lane.
Notes to Installation 3.2
When installing the Radar, make sure that:

Keep the Radar as horizontal as possible. Check whether the leveling bubble on the rear
panel of the Radar is in the middle. If not, fine-tune the installation angle of the Radar.
Keep the Radar horizontal Figure 3-1

The radar beams can cover the entire area to be detected.
When the installation height is confirmed and the Radar is kept at horizontal position, the
Radar coverage depends on the elevation angle and the azimuth angle.
3.2.1 Adjusting Elevation Angle of Radar
The elevation angle of the Radar refers to the angle between the normal line of the front cover
and the horizontal line.
