Use the Ø24 hole saw bit to drill sensor holes.
2nd step.
Install the masker onto a flat bumper surface vertically to the ground and
rotate the masker until it is flush with the surface of the bumper.
Please remove the burrs
around the sensor holes after
drilling. Please make sure of
the size of the sensor holes
and there is no materials

7. Limitations
The sensors may not work if an object does not reflect the ultrasonic waves or it
has an unusual shape e.g. poles/bollards, cardboard cartons, motorcycle/bicycle
tires, small or slender trees. The sensor may not detect another vehicle bumper
if it is too high, (Please see examples below)
Final Step.
Install sensors from the inside of rear bumper and fasten sensors to the maskers.
Please ensure that the face of the sensor should be perpendicular to the ground
and fixed with the masker.
The sensor must be at 180
o
to the ground after installing on the bumper.
