Vertical Aiming NOTE: When the millimeter wave radar unit is adjusted on a surface that has more than 1 degree of horizontal slope (drainage slope), the vertical aiming cannot be adjusted correctly. Check the levelness of the surface, and adjust the angle of the millimeter wave radar unit to be parrallel to that of the surface, lay a ruler (at least 12'') or other flat straight objects on the surface and put the level on top to confirm the levelness of the surface.

1. Put the level (A) (commercially available) on the aiming pad (B) of the millimeter wave radar unit.

1. Turn the vertical adjusting bolt (C) on the driver's side with a screwdriver, and adjust the angle of the millimeter wave radar unit so that the air bubble in the level is centered.
