3. Installation and wiring
IMPORTANT : The mounting position of the sensors is very critical and directly
affects the performance of the system operation.
Mounting method 1 (Fix sensor with double-sided sticker)
Step 1 : Find out the place for mounting sensors, for a general vehicle the most
suitable mounting position is between the top of the bumper near the
reverse lights. Or mount the sensors on the bottom right and bottom
left of the boot cover (see Fig. 2A). Don’t mount the sensors in front of
the bumper. Determine the space between two sensors and the height
from the road surface.
Step 2 : Clean the place where the sensors will be mounted, slip the rubber pad
(part item 6-1) onto the sensor’s bottom then fix the sensors with strong
adhesive tape. Insert the lead cables through the gap between the car
body and boot cover into the vehicle (see Fig. 2B)
Step 3 : Determine the mounting position of the control unit and buzzer, taking
into account the cable length and space available, ensure you can hear
the buzzer from the driving compartment. Fix the control unit and
buzzer with strong adhesive tape.
NOTE : 1. We recommend this mounting type because it’s easier.
2. Glue the sensor on the boot cover at least 65cm above the road surface. If
the mounting surface is slant or not flat, please cut the extra adhesive
stickers and use them to flatten the mounting angle, keep the angle
strictly vertical and horizontal.

Mounting method 2 (Fix sensor with bracket)
Step 1 : Assemble the sensor and bracket with self-tapping screw (part item 6-
7) then tie up the cable on small holes on the bracket with wire band
(part item 6-6) (see Fig. 2E).
Determine the place for mounting sensors bracket, for a general vehicle
the most suitable mounting position for the sensor bracket is beneath
the bumper. Determine the space between the two sensors will be
mounted and the height from road surface (see Fig. 2F)
Step 2 : Clean the place where the sensor’s bracket / fix the sensor’s bracket
with self-tapping screw provided (part item 6-8). Insert the lead cables
through the gap between the car body and bumper to the drain hole
under the chassis or gap between the car body and boot into the
vehicle.
Step 3 : Determine the mounting position of the control unit and buzzer, takin g
into account the cable length and space available, ensure you can hear
the buzzer from the driving compartment. Fix them with strong
adhesive tape.
NOTE : 1. Do not apply great force to the sensor.
2. Do not mount the control unit and buzzer outside the car.
3. Mount the sensor and bracket on the bumper at least 30cm, above ground,
(the mounting bracket is bent upwards 45 degrees). If necessary, you can
bend the bracket to adjust the detection angle. (Prevent picking up the
road surface)

Wiring guide (see wiring diagram (See Fig. 2I)
1. There are 3 female sockets on the control unit, the wiring between the power,
buzzer, sensors and control unit is as follows.
#1 Power & buzzer line connector (4pin)
Insert the 4-pin plug (part item 5) into the 4-pin socket on the electronic
control unit (ECU), and plug the 2-pin connector that is attached on another
side together with the buzzer’s 2-pin female housing ; the remaining "Red" and
"Black" wires must be wired as follows :
(Red) "+" Terminal of power supply, connect to "Positive" wire of
reverse lights with wire pincer (part item 6-2)
(Black) "-" Terminal of power supply, connect to "Negative" wire of
reverse lights with wire pincer (part item 6-2)
#2 Sensor male connector (2-pin)
Plug 2-pin male connector of longer sensor cable (part item 3) into the one 2-
pin female socket on ECU.
#3 Sensor male connector (2 pin)
Plug 2-pin male connector of shorter sensor cable (part item 2) into the other
2-pin female socket on ECU.
NOTE : #2 and #3 connectors are interchangeable.
2. After the "Operation and Testing" procedures stated below, clean the entire wiring
loom and attach it with wire band.

4. Operating and Testing
Step 1 : (Ensure the electronic buzzer works)
After installation, move the vehicle to an area where there are no obstacles
within the range of the sensor. Start the vehicle’s engine and place the
transmission gear in "reverse" position. This means "switch ON the
system", the buzzer will beep once for approximately one second to
indicate that operation is normal. (The buzzer is mounted inside the boot)
NOTE :
1. To avoid discharging the car battery, do not turn the unit ON unless the
engine is running.
Step 2 : (Verifying the system can produce different specific sounds when in the
proximity of an obstacle)
When the vehicle is within 90cm of an obstacle, the electronic buzzer will
beep slowly intermittently to indicate an obstacle is nearby. When an
obstacle is within 60cm, the buzzer will change to beeping quickly
intermittently and if it is within 40cm, the buzzer will beep continuously.
(See Fig.-4A)
NOTE :
1. Maintain a slow speed of less than 5 km/hour when close to an
obstacle.
2. When you hear the buzzer change from a quick beep to a continuous
beep, please step on the brake immediately to stop the vehicle.
3. When reversing, as soon as the vehicle comes to obstacle within 40cm,
the buzzer will start to "beep" continuously, this continuous beep will
remain even if the vehicle moves further away keeping within a rnage
of 90cm. This hysteresis function provides more safety than actually
required
4. Reversing the vehicle up or down a slope may cause a false alarm, but
it will also remind you to be careful in this situation. (See Fig. 3B &
Fig. 3C)
5. If you encounter problems during operation and testing, please refer to
the "Trouble shooting" table below.
6. When you have completed the above procedure, installation is
complete and the system is ready for use.
