Installation
Install the sensor between 1.5 ft. and 2.25 ft.
above the ground level for optimum performance
and mount on the outer edges of the vehicle’s rear.
NOTE:
Mounting the sensors on the rear tip of the vehicle
is NOT recommended as the sensors may get damaged if
rear ended.
To mount the sensors, mark four equally-spaced
points with the two outer sensors no more than 2.5
ft. apart. See the diagram below for hole sizes.
NOTE:
Be sure to check the behind the drill area for
obstructions or reinforcements bars.
It is important not drill the hole larger than the
measurement indicated.
Installation Tips
The sensor should be mounted vertically and
level; mounting on a tilt or unleveled surface will
affect sensor performance.
To avoid false warnings from the sensor be sure
there are no obstructions within a 90 degree
lateral range.
After routing and attaching the cables, use a
small block of wood to press the sensors into
place.
