Service Procedure
Horizontal Alignment (Azimuth)
The Antenna Assembly must be facing straight ahead (azi-
muth) of the truck in order to optimally detect objects in the
same lane as the truck is driving.
1. Select two truck reference points that are identical
and symmetrical about the truck centerline. Ensure
the reference points selected are equally aligned.
Items such as fenders and headlights should not be
damaged or distorted, otherwise, the alignment will
be incorrect.
2. Place a 6’ (2 m) long straight edge across the
Antenna Assembly face. Center the straight edge
horizontally.
3. Measure the distance between the reference points
and the face of the straight edge.
4. Adjust the Antenna Assembly, if necessary, left or
right until the two measurement points are equal,
within ± ¼ " (.6 mm). Determine from the measure-
ment which side of the Antenna Assembly needs to
be adjusted.
For example, if the right side of the Antenna
Assembly needs to come forward to make the
measurement to the reference point on each
side of the straight edge equal, loosen only the
two (2) 5/32" (4 mm) allen screws on the right
side of the Antenna Assembly. Move the
Antenna Assembly forward until the measure-
ment is equal. This will maintain the Antenna
Assembly at -.5° vertical down position.
5. Torque the four (4) 10/32 screws with a 5/32"
(4 mm) allen wrench to 24-26 lbs. in. (2.7-2.9 N•m).
6. Repeat steps for Vertical Alignment and Horizontal
Alignment until the criteria for both steps are met
without any adjustments.
