INTRODUCTION
Congratulations on your purchase of the HAWK HRA-7800 back up sensor, designed to aid operation
when backing up your vehicle. Simple to operate and use, the HAWK HRA-7800 back up sensor

Installation Diagram
The following illustration shows the general location of the components of the backup system.
Note: Before drilling any holes in the vehicle ensure that the area behind is clear of any electrical,
hydraulic, or support members etc.
1. Drill the holes in the bumper as indicated in the installation diagrams below and install the
sensors. Sensors 1, 4, 5 and 8 should NOT be mounted on the curve of the bumper.
2. Install the sensor vertically; the “up” arrow must be pointing upwards.
3. Connect the Red wire of the control unit to the (+) positive of ignition wire.
4. Connect the Black wire (-) to the vehicleʼs chassis.
5. Connect yellow wire to the (+) positive wire of the vehicle reverse indicating light.
6. Install the triggering micro switch on the panel, system will work when pressing the
triggering switch. It is especially helpful when you want to park the car inside of the
garage without engaging reverse gear. System will stay on for 2 minutes.
7. Clean the area of the dashboard where the LCD display is going to be mounted.
8. Remove the sticker off the bottom of display. Also remove protective screen cover from
LCD screen.

False Readings
Detection errors may occur due to the following
cases:
Smooth sloping surface
Smooth round object
Items absorbing sound, e.g. cotton
1. Heavy rain or snow, a contaminated or damaged sensor(s) could result in detection errors.
2. Clean sensors of any mud or debris. Immediately replace any damaged sensor when
detected by the system.
3. Heavy smoke or vapour from exhaust, due to a cold start or a poorly running engine can
also result in a false reading.
4. The performance may be affected if installed on metal bumper.
Self-Test function
The back-up system only activates when the vehicle is placed in reverse gear. When placed in
reverse gear the system first does a diagnostic check to ensure the system is fully functional and
reports any sensor malfunctions within the back- up system. If there is any malfunction with the
sensors, the LCD display will show following error message.
EE Check sensor make sure sensor facing up or connected properly.
EC Check control box make sure all cables connected properly.
Installation
Note: Before installing system let the components of the exhaust system cool down. This will make
the installation safer and preclude heat damage to the backup sensor wiring or components.

Installation
1. Installation of the screen
The screen stick on the panel
Which suitable for the driver
2. Installation of detectors
1. The sensors 5 and
8 must be installed at
Same level.
2. The distance between
The ground and the sensors
is about 50-65cm,suggested
55cm.
3. The sensors must be
installed perpendicular to
bumper & avoid attach-
ing on the metal.
4. To ensure the best detect
position, the sensors 5 & 8
must be installed beside the
edge 30-40cm, suggested 30cm.
5. After measurement,
make a symbol.
6. To ensure best detecting results, the
sensors 1 & 4 must be installed near the
edge 8-13cm, suggested 11cm.
7. Measuring the distance between
sensors 1 & 4 and marking a (L) sign.
8. Marking the points of sen-
sors 2 & 3 by 1/3 L. 9. Using the 20mm drill, drill
through the point which is
marked, secure the sensors
into the holes.
3. Installation of main unit
1. The main unit must be in-
stalled in the trunk to avoid
moisture & heat.
2. Lead out the power wire from
the startup facility of the vehicle,
connect it to the power supply wire
of the main unit.
3. Plug the power supply wire,
screen wire & sensors wire re-
spectively to the inputs of the
main unit family.
Install the sensor vertically , the “up” sign must be on upside.
After installation Test
Use the following to test and verify the operation of the backup system.
Warning: Do not stand behind a moving vehicle death or injury could occur. Prior to
testing, set the hand brake On, ignition key On (do not start), step foot on brake and shift the vehicle
into reverse. Ensure that the engine is not running while proceeding with the following tests.
Test the system operation with a piece of wood (8 inches wide x 3 feet, 3 inches high) after the
installation. Start with the wood more than 8.4 feet away from the vehicle. Then move the wood
closer to the vehicle and ensure that the buzzer and voice audible, LCD, and distance indicators
display correctly.
.
Trouble shooting
No buzzer or display at power up?
1. Is power wire connected to ECU correctly?
2. Verify (+) 12v at ECU when vehicle is in reverse.
3. Verify the ground connection.
4. Have you connected to the correct reversing indicator wire?
5. Do you have a minimum of (+) 12V and ground at the display?
False warning tone or false LCD flashing
1. Is the sensor mounted too low or pointing to the ground?
Sensors do not detect any objects?
1. Is the vehicleʼs exhaust smoking? Correct or allow it to clear before proceeding with
testing.
2. Are sensors properly plugged into the correct sockets?
