Adjusting the Trip Points:
The trip points are factory set as ordered. If necessary, these can be adjusted with a small screwdriver. Remove
the cover to access the adjustments. See the diagram for locations. Turning counter clockwise (CCW) increases
the speed setting. Make only a small change then recheck the trip point.

Installation Hints:

1.) Unit is not sealed…mount inside cab, etc., away from harsh environments.
2.) Ground enclosure to help shield against CB or other radio interference.
