5.6 Replacing the Azimuth Limit
Switch Assembly
1. Rotate the antenna assembly, by hand, clockwise
until it stops.
2. Remove the PCB cover as explained in “Removing
the PCB Cover” on page 108.
3. At the main PCB, cut the black and white wires
from the azimuth limit switch Molex connector
(see Figure 5-3 on page 109). Leave about an inch
of the wires still connected at the Molex connector
for later reference.
4. At the azimuth limit switch cover, remove the hot
melt holding the black and white wires in place
(see Figure 5-7).
5. Remove the three #6-32 retaining screws from the
limit switch cover and set aside (see Figure 5-7).
Lift the cover to access the limit switch
underneath.
6. Remove the four #8-32 screws securing the limit
switch to the cover and set aside.
7. Replace the azimuth limit switch. Attach the new
switch to the cover using the #8-32 screws, flat
washers, and cable clamp.

When rotating the antenna by
hand, go slowly! Hitting the
mechanical stops with excessive
force will damage the azimuth limit
switch.
