Product: HawkEye Plus and HawkEye HELP GARD Plus
Model #: HRASP401-A, HRASP401-A60, s-HGPkit1, s-HGPkit2, s-HGP60kit1 and
s-HGP60kit2.
Vehicle: All vehicles with a reverse alarm and HawkEye Plus installed.
Issue: Installation of other after market components may cause interference with the sensitivity
of HawkEye Plus.
Action: During installation of HawkEye Plus, the vehicle reverse lamp circuit is used to power
the HawkEye Plus control module. If using an external rear backup alarm or other system, do not
attach the HawkEye Plus power wire to the same side tail-lamp wire as the backup alarm or it may
interfere with HawkEye Plus operation.
Example: If the external backup alarm gets power from the right tail-lamp wire, the HawkEye
power wire must be attached to the left side tail-lamp wire.

GUIDE TO ADJUST SYSTEM SENSITIVITY (POTENTIOMETER # 1 ONLY)
NOTE: Potentiometer # 2 and potentiometer# 3 are currently not
used.
1. Open the control module cover using a small screwdriver.
2. Use a cart or other mobile object with a piece of 3/4"
plywood (18"x24") on the side facing the sensors (Fig. 1).
A dense material is required to absorb the ultra sonic
waves.
3. Position the cart in the direct path of a sensor at the
distance of five feet.

(Fig. 1)

4. Insert a small screwdriver into the # 1 potentiometer (Fig. 2) and gently turn the
potentiometer clockwise to the stopping point.

(Fig. 2)

(Fig. 3)

5. Set the park brake, block the wheels and place the transmission in reverse. The display
panel should now have a blank reading.
6. Slowly turn the potentiometer counter-clockwise until the display gives a numerical
reading of the distance of the cart and has a consistent audible sound.
7. Reset the module by placing the vehicle in park or by unplugging the module power
connector. Removing the power from the module allows the module to recognize the
new sensitivity adjustment.
8. Place vehicle in reverse or reinstall the module power connector. Move the cart away
from the bus and note the display readings. Move the cart forward, measure the cart
distance and compare the distance with the display reading.
9. Adjust the sensitivity further if needed. Turning the potentiometer clockwise reduces the
sensitivity and turning the potentiometer counter-clockwise increases sensitivity. Note:
the potentiometer adjustment range is from 0 to 80 degrees (see Fig. 3).
10. Repeat Post-Installation Testing. If necessary, readjust and retest.
11. Replace cover on the back of the Control Module.
