Put the bottom of the laser pointer on the middle of the front cover, and then adjust the
elevation angle of the Radar, until the laser spot is located at the distance shown in Table
3-4, Table 3-5, and Table 3-6.

3.2.2 Adjusting Azimuth Angle of Radar
The azimuth angle of radar refers to the angle between the normal line of the front cover and
the direction of moving vehicles. The broken yellow lines represent the boundaries of the radar
beam, while the blue line represents the central line of the radar beam.
When the Radar is installed right above the lane, make sure that the radar beam is as parallel
as possible to the vehicle movement direction. See Figure 3-3.
For roadside installation, make sure that the center of the radar beam is aimed at the middle
area of the detected lane. See Figure 3-4. Use a laser pointer to help you aim the radar beam at
the middle area of the detected lane.
