When the key is turned to the “ON” position and the Reverse gear is engaged,
the system is activated. If an obstacle is detected, its distance will be shown on
the display, along with an audible tone and visual alert.
The alarm method is as follows:
Audible and Visual Warning Display will show the obstacle distance and provide
warning beeps according to the distance of the obstacle. The alarm section will
be divided into 5 equal segments according to the farthest detection distance.

(3) Rear Parking Assistant
When the key is turned to ON and R gear is engaged, the system starts to work, and the detected
demerit is recorded through the display to give an audible and visual alarm to remind the driver.
If there is no RCTA alarm, then follow the reversing working mode. The alarm method is as follows:
a. If there's an obstacle being detected, the trigger cable will provide a low level output, and if
there's being detected, it will provide floating output
b. Audible and visible warning Display show object distance and provide warning beep according
to the distance of the object; The alarm section be will divided into 5 segments equally according
to the farthest detection distance.

4: Learning Function
When the installation position of the radar is not at the outermost side of the
vehicle, the radar can easily detect the vehicle body, or vehicle accessories in the
rear bumper area, which can result in a false alarm. Therefore, it is necessary to
enter the learning mode to teach the radar to ignore the obstacle causing false
alerts.
Use the following steps to go through the learning function.
A. Move the vehicle to an open area and confirm that there are no obstacles
other than body accessories within (a*b) distances of the radar.
(4) Learning Function

make the radar ignore the object.
Users need to follow the following steps to realize the learning function:

INSTALLATION NOTES
1: This product is designed to work with 12-24V battery vehicles.
2: The front of the radar sensor should not be covered by metal objects.
3: Connect cables according to the labels.
4: Make sure the wiring harness is secured and far away from heat
sources, sharp edges and any moving vehicle components. Avoid pulling on the
harnesses.
5: Wrap all wire to wire connections with electrical tape, or cover with heat
shrink.
6: If there is ice or dirt on the surface of the sensor, please clean it off for the best
operation. Paint will also affect the detection ability.
7: Obstacles such as soft sponges, spheres, and sharp pointed objects can not
be detected easily.
