Operating Instructions
7 
The output is switched from a high impedance state to ground when activated and is protected 
against over-current or short-circuit. The maximum operating current is approximately 200 mA. 
7. Testing   
1.  Switch the gear to reverse, reversing lights will turn on automatically. The on-screen display 
will provide real-time information to the vehicle driver about the danger zones surrounding the 
vehicle. When an obstacle is detected, the image of the vehicle on the screen lets the driver 
know that the corresponding area is not clear through the use of colored arc, and distance 
value is shown too. 
2.  Connect one input cable from a sensor to the master controller. If no obstacle in front of the 
sensor, there is a green icon in corresponding place. In Front-Rear Mode, the sensor could 
properly find a person standing within 3.0 meters right/left in front of the sensor. When sensors 
are placed at front and rear sides of the vehicle, four levels of arc will appear on corresponding 
place. The colors of warning arc are Red, Yellow, Dark Green and Green. While the sensors 
are placed at left/right side, the colors of warning arc are Red, Yellow and Green. In Left-Right 
Mode, the sensor could properly find a person standing within 3.0 meters all of sensors, the 
colors of warning arc are Red, Yellow, Dark Green. Remove the sensor and connect others 
one by one for testing in the same way. 
3.  After finishing testing. Connect all the sensors with the controllers. 
4.  Notice: *Most problems occurred in the testing are usually caused by improper installation of 
the sensors, they may be solved in actual application.
