1. The car must be in power-off, when installing ultrasonic sensors
2. Its performance may be affected in following situation: heavy rain, gravel road, bumpy 

road sloping road and bush, very cold, hot or moist weather, or the sensors is firned or 
iced over.

3. Switches among ultrasonic, electric wave, DC and AC and those among 24V, 12V 

voltages may also effects its performance.

4. The sensors should be installed appropriate loose or tight.
5. Its performance will be effected if the sensors are fixed on metallic bumper.
6. Avoid installing the digital control box in places of great interference, such as vent-pipe, 

wiring nearby.

7. Test the system to make sure it works normally before using.
8. This system is a reversing aid and the manufacturer will take no responsibility for any 

accidents caused after the kit is installed.

    H-066 Parking Sensor System consists of ultrasonic sensors, digital control box  and LCD 
display. The system detects the distance between the car and front/rear obstruction by 
ultrasonic sensors  installed at the front/rear bumper of car. The distance will be  displayed 
in an innovative mode with the special designed LCD, numeric  display and step-up sounds, 
which will be changed according to the actual positions detected obstruction so that the 
driver could judge the distance and avoid accident.

1.  Choose right installation position for sensors
2.  Select drilling position for sensor A & D

Select drilling position for sensor 1 & 4

3.  Select drilling position for sensor B & C

Select drilling position for sensor 2 & 3

4.  Locate the position and drill
5.  Install the sensors and hide wires
6.  Install the display
7.  Install the control box
8. Connect the whole system according to the General Installation Diagram

( Rear detection )

1. Adjust the directions of the sensors and axial orientation, neaten the wiring after installing 

the sensors.

2. Connect the power supply of back control box to  the reversing light. Connect  the power 

supply of front control box  to auto ignition switch.

3. Connect the data wires between the front control box and display, and disposal the 

control switch with front control box. Do not disposal the sensor at the moment.

4. When the car is started, the horn sounds "Dang,Dang" to enter into  working status , 2s 

later, it turns to standby status. Put the car into back gear, then the display shows "En" 
(n=0,1,2

)to show  the number of defective sensors, with the indication of exact 

defective sensors. Insert one of the sensors into corresponding interface in front/back 
control box. Human being could be detected normally, if he stands within 0.7m right 
before the sensor; Pull out the sensor, and check other sensors in the same method. 
Insert all the sensors in corresponding interfaces after testing.

Test: a. After connect a sensor with  the control box, if the buzzer sounds"Bi

", please 

check whether there is any obstacle around it, 

or the sensor is fixed too tight or close to 

great interference sources(such as vent-pipe, wires) ;b. If the display shows any distance 
figure with no obstacle around the sensor, the sensor may detect  the ground or some 
outshoots of the car(such as registration mark etc.), please check the directions of sensor 
and axes; c. If the system still could not work properly after the above mentioned handling,  
the sensor(s ) can be deemed defective, or unmatch with the control  box. The system 
should be replaced.

Note: a. The connection between sensor and the digital control box is unique. b. It performs 

as: when detecting within 0.3m, it shows "0.0", instead of 0.1-0.2 to alert which requires 
the driver to stop immediately.
