5. See Figure 10 on next page: Remove the cable compression plate and rubber ring and pass
the cable up through the opening. Replace the rubber ring and secure the cable with the
compression plate. Attach the 7-pin connector to X11 and the 9-pin connector to X12 of the
printed circuit board (PCB).
6. Replace the aluminum shield cover. Lay the cable shield into the channel machined into the
aluminum housing. Be careful that the cable won't get caught between the main unit and
the cover. Make sure the antenna rotates freely and that the scanner cable does not obstruct
the rotation of the antenna.
7. Replace the upper part of the radome, making sure you don't bump it against the antenna.
Make sure the radome cover is positioned in the correct direction, as shown in Figure 11. The
upper and lower parts of the radome each have four alignment markings indicating screw
positions.
8. Connect the antenna cable to the plug labeled SCANNER on the rear panel of the control
box. Be sure to secure the rubber boot around the cable connector rim.
