NOTE:
The sensing unit must be mounted to a solid surface and must not be exposed to any heat sources. Toward the middle of the
vehicle but outside the frame rails is best. The sensing unit may be mounted between frame rails on pusher vehicles and trailers.
The sensing unit may be mounted in a compartment but needs to be protected from stored objects. It is critical that the sensing
unit is mounted in the proper position according to the sticker on the sensing unit. (See figure below). The springs should be com-
pressed to approximately 1.25 inches.
The correct method for adjusting the sensor is as follows:
First, level the vehicle by placing a 24" level in the center of the vehicle on the floor. With the vehicle level adjust the sensing unit
until all yellow lights are out. This is done by drawingup or backing out the sensing unit screws. If a front light is on, adjust the
front screw. If a side light is on adjust the side screw. If a rear light is on adjust the rear screws. One or more screws may have
to be adjusted to turn the yellow lights out. After adjustment has been made, pull down on the sensing unit to make sure the unit
is bottomed out on the screw heads. Check to make sure all yellow lights are out. If not, readjust. Rock the vehicle and re-
check for yellow lights, readjust if needed.
