1.Fix the solar panel on the frame, and then fixed on the speed feedback instrument with screws and nuts. The white wires are used to connect the solar panels and the batteries in the speed feedback box, and the positive and negative electrodes are connected one by one.
2.The speed feedback device fixed on the road left or right, or just above the road ,so that the direction of the radar port to the car, the tilt angle of not more than 15 degrees, if it is fixed above the road, the radar fixed position should be radar Cavity oblique angle alignment to the car location. At the same time, the higher the distance between the radar and the ground, the farther away the radar work. Generally, The distance from the ground to radar in 2-7 m is better.
3.Open the speed feedback device's back cover, connected The radar data cable, control board connector one by one. And then adjust of the radar position, so that it position the car.
4.When the speed feedback device over the top,fixed the speed feedback with a screw to the column.
