The PCBs are mounted to the antenna elevation mechanism
support frame with machine screws and are interconnected by
means of keyed Molex connectors. Figure 5-3 shows the PCB
arrangement, connector locations, and functions while Figure 5-4
on the next page shows how the printed circuit boards are
mounted to the support frame.

The PCB cover fits snugly over the
PCB. When removing or replacing
the cover, take care to ensure that
the cover does not dislodge any of
the Molex connectors as this will
cause system errors and improper
operation.
