The Backup Parking Sensor System determines obstacle distance by measuring the time needed for the ultrasonic wave emitted by a sensor to reach an obstacle and for the sensor to receive the ultrasonic wave reflected from the obstacle. Given the speed of the ultrasonic wave, the system can then calculate and display the distance between the sensor and the obstacle.

To have the look of factory installed system, the system comes with 4 in-bumper type sensors to be installed in the rear bumper by drilling holes through the bumper.  The main control box is powered by tapping into the back up light wires so that the system will work only when vehicle is put in reverse.  It is supplied with a wireless LED digital display which shows the exact distance from an obstacle and eliminates the wiring between the display and main control box. The wireless display can be mounted up to 20m (66 feet) away from the main control box (still requires its own +12V power supply). This is especially convenient for installation on long vehicles.  The wireless display gets its power from cigarette lighter, ACC or ignition switch.  Seven (7) LED Lights (3xGreen/2xYellow/2xRed) on each side of the wireless display indicate both orientation of obstacles and Safe/Warning/Stop zone.  The audible alert (beeper) with on/off switch is built in the wireless display. It beeps faster as vehicle gets closer to obstacle and sounds continuously when vehicle is within 0.3m (1ft) from obstacle.

Installation and Wiring

IMPORTANT: (a) Read this manual thoroughly before proceeding to installation. You can also have the system installed by a professional installer such as your local auto mechanic/auto electrician/car stereo store. (b) Turn off the engine and ACC during installation. (c) Double check that all wiring is correct before powering on the system. (d) During installation, avoid flatting, perforating, cutting, and extending the wires of sensors to reduce unnecessary signal loss.

1. Installation of the Main Control Box

a) Find a flat and clean surface inside the vehicle close to driver's side taillight assembly as the main control box

gets its power from the back up light and has all the rear sensors plugged into it. For trucks, you may install it inside the driver's side taillight assembly. Keep it away from areas of high heat, high humidity, direct water contact, direct sunlight, and electromagnetic devices.

b) Place the main control box in place temporarily without securing it to the vehicle as you may need to adjust

the location of the main control box while wiring.

c) After completing all wiring, use the double-sided self-adhesive pad included to secure the main control box to

the vehicle.

2. Installation of the Wireless LED Digital Display

a) Find a place for the wireless display on top of the dashboard where the driver can see it easily. Place the

wireless display in place temporarily without securing it to the top of the dashboard.

b) After completing all wiring, secure it with the included self-adhesive pad on the bottom of the display base.

3. Wiring Power Supply to the Wireless LED Digital Display

There are two methods for powering the wireless display: a) Method [1]: The wireless display comes with attached power cable and a cigarette lighter type plug. Simply

Insert the plug into the cigarette lighter jack.(Fig. 4).

b) Method [2]: If you want to route and hide the power cable of the display, you may cut off the cigarette lighter

type plug from the power cable, and wire the cable directly to ACC or "ON" block of the ignition switch. Strip 1" of the wires. Connect the red wire to +12V and the black wire to (-) negative or chassis ground. Wrap the connections with vinyl electrical tape.

4. Wiring Power Supply to the Main Control Box

a) Insert the 3-pin plug of the power cable of the main control box into its socket labeled PWR on the side of the

main control box (Fig. 3).

b) Locate the +12V and the (-) negative wires from the back up light near the taillight assembly. If necessary,

remove the taillight assembly to locate them.

c) Strip 1/2" of the wires found. d) Connect the red wire of the power cable to the +12V wire (Fig. 3) e) Connect the black wire of the power cable to the (-) negative or chassis ground (Fig. 3). f) Wrap the connections with vinyl electrical tape.

5. Installation of the Sensors IMPORTANT: (a) To avoid false alert from the system detecting the ground, the sensors should be mounted

between 50cm to 80cm (20" to 32") above the ground and the face of the sensors need to be vertical or slightly upward angled (Fig. 2). (b) Horizontally, the sensors should be equally spaced if possible or symmetric to the center of the bumper. (c) The outer two sensors should be mounted about 15cm (5.9") from the corner of the bumper for better corner coverage.

Note: The bumper surface for mounting the sensors should be as flat and vertical as possible.

a) Refer to Fig. 1 for mounting height and position of the sensors. b) Work under the rear bumper to check the internal structure of it before marking the positions for drilling holes.

If the view is blocked, you may need to remove the bumper.

c) With chalk or marker, mark the position of sensors on the rear bumper. Make sure that the sensors can be

pushed all the way in and that you can feed the wires through.

d) Drill the holes through the bumper at the marks with the Φ21mm drill bit included. Note: if drilling through

metal bumper, use a bi-metal

Φ21mm (13/16") drill bit (not included).

e) If necessary, smooth the sharp edge of the holes with a polishing head or small round file. f) If you have a non-vertical bumper, you may need to use the wedge-shaped plastic sensor spacers

provided. Carefully push each sensor into its sensor spacer.

g) Run the sensor wires into the holes drilled. Push the sensors into the holes. Note: When pushing in the

sensors only apply pressure at the edges, not on the middle of the sensor to avoid damage to the sensor element. The sensors are tapered for a snug fit.

h) Run the sensor wires from the bumper into the trunk or inside of the vehicle through the existing small vent or

rubber grommet in the rear of the trunk or vehicle, and to the main control box. Note: Do not cut the sensors

wires.

i) Attach sensor wires to the vehicle body with cable/wire ties so that they will not get in the way of any moving

parts and there are no loose wires hanging down.

j) Plug one sensor at a time into its corresponding socket at the main control box, start the engine and put the

vehicle in reverse, the display should show the correct obstacle distance. Repeat the procedure for the remaining sensors.

Testing Your New Backup Parking Sensor System

Back your vehicle slowly (about 3 miles per hour) to approximately 2.5m (8.2 feet) from a flat vertical surface such as a wall. Continue to back up slowly and check the performance against Chart 1.

Note:

[1] The wireless display will light up only when the main control box is on (vehicle is in reverse).

[2] When you shift into reverse gear, the system will beep once indicating it is activated.

Using the Wireless Digital Display

The display has a built-in beeper (audible alert). There are seven (7) LED Lights (Green/Yellow/Red) on each side of the two-digit distance display (Fig. 4). The color LED lights have two functions: indicating the orientation of obstacle and showing if you are in Safe/Warning/Stop zone (Chart. 1).

Warning

z To avoid collision with obstacle because of the inertia of vehicle while backing up/parking, keep your vehicle

speed at about 3 miles per hour and stop the vehicle immediately once you hear the continuous beeping.

This is because even if brake is applied, your vehicle will still go for some distance (inertia) before it comes to a complete stop.

z Because the back up parking system detects obstacle by emitting ultrasonic wave and receiving reflected

ultrasonic wave from obstacle, the system may fail to give both visual and audible alert if an obstacle has smooth ball-shaped or sloped surfaces as such surfaces may not reflect ultrasonic wave back to the sensors. Drivers in these situations should pay more attention while parking their vehicles.

z In heavy falling rain or snow, the system may give alert as falling rain or snow may be detected as obstacles.

Keep surface of sensors clean of snow, mud, dirt, and other debris. Turn the beeper off if needed.
