Refer servicing to qualified service personnel.
This symbol is intended to alert the user to the presence of uninsulated "dangerous
voltage" within the product's enclosure that may be of sufficient magnitude to
constitute risk of electric shock to persons.
This symbol is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying the appliance.
This symbol is intended to alert the user not to dispose of electrical and electronic equipment
1. Remove all the cable connections from the monitor before cleaning the device.
2. Clean the sensor face of any accumulation of dirt, mud, snow, ice, or debris.
3. Visually inspect the attached wiring and cable and verify that they are properly secured
and not damaged. Inspect the Radar Sensor and control box and verify that they are
securely attached to the vehicle.
.
CAUTION
You are cautioned that any changes or modifications not expressly approved in this manual
couldvoid your warranty and necessitate repairs.

2. Hints for Users
1. When triggered to work, the ultrasonic obstacle detection system will start alerting after a
one-second delay.
2. If reversing at high speed, expect the ultrasonic obstacle detection system to have a
one-second delay before emitting a warning.
3. While reversing, it is indispensable to use the ultrasonic obstacle detection system. However,
the product is meant as an assisting device for safety. We declare that the safety responsibility
is borne by the driver. Make sure to keep the car at proper speed and pay attention to the
surrounding conditions while reversing.
4. There may be improper reception, deviation and error in reflected signal because of difference
in material, angle or size of obstacles.

1. The ultrasonic sensor detection system consists of a master controller, extension controller, 12
ultrasonic sensors and accessories.
2. The entire system will work automatically when the reverse gear is engaged.
3. The on-screen display will provide real-time information to the vehicle driver about the danger
zones surrounding the vehicle.
5. Product Installation
Fig.1 installation instruction
1st step
Install the sensors on a suitable place. The distance between sensor S6 / S7 and S1 / S12 must be
more than 1.5m, and other adjacent sensors should be installed more than 0.5m. Ideally the sensors
should be installed on the vehicle at roughly 0.6m to 0.8m above the ground.
2nd step
Make sure the sensor is installed so that it is firm and steady.
5
Installation of other parts
1. Find the right place for camera mounting. e.g.: Drill a hole to install the embedded style
camera.
2. Find a proper place in the cab to mount the monitor.
3. Master and extension controller should be placed in a clean and dry place.
6. Connection
1. Please pay attention to the custom wire harness for connection between the ultrasonic sensor
kit and the back-up system. Make sure that reverse trigger wire from the harness is connected
to the reverse light or is hardwired to power if the camera monitor is already wired accordingly.
2. Connect the 5PIN FEMALE jack to the Monitor and 5PIN MALE plug for camera.
3. The master controller should be hooked by the custom wire harness for VIDEO IN & VIDEO
OUT. The port (Data Link) on the bottom-right of the master controller is connected to the
bottom-left port (Data Link) of the extension controller via the 461-10 Data Link cable.
4. The sensor input cables should be plugged in sequence.
5. The controllers and camera are both powered by the monitor, which is powered by the vehicle
battery.
6. Notice: *Leave the input cables from the sensors unconnected for testing.

Trigger in
The system provides an auxiliary input that allows an external signal input to change the sensor
status between standby and active. As a backing sensor application, single white wire of extension
cable connects to positive power wire of the back-up light.
Alarm out
The system provides an auxiliary output that triggers an external device whenever the sensor
detects an object. This output can be used to activate an external backup alarm or a light beacon.
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.
