Plug the free end of the ribbon cable into P504 on the I/O board or, if the P3SVGA board is installed, into

P102 on the P3SVGA board. Be sure the red edge is at the Pin 1 end of the connector (the end nearest the

bottom). To avoid stressing the board, support it with your fingers while mating the connector by placing your

fingers on the side of the board opposite the connector and squeezing the connector in place with your thumbs.

Be sure the connectors are properly aligned so that all pins engage the cable connector just as you did on the

display board (see Figure 19).

Locate the TMP coaxial cable. Plug one end into J902 on the RF board and the other end into RF IN, J100

on the front panel board. The connectors simply press into the sockets and are held in place by friction. If a

connector refuses to engage, check for excess loose center conductor wires (see Figure 20).

Figure 20. TMP Connectors.

Check the position of the jumper block on P502 on the I/O board (in the top corner just above the ribbon

connector) and place it according to how you want the

P O W E R

switch to operate (see Configuration on page

30).

Inspect the inside surface of the side covers to ensure there is bare metal around each screw hold for good

contact with the angle brackets or 2D fasteners. Be sure that you clean away paint on the inside surface, not the

outside (see Figure 10, page 49). The screws holes are not countersunk on the inside surface of the panels. They

are countersunk on the outside surface.

IMPORTANT: Do not over-tighten the case screws in the following step or when

mounting the top cover later. You can strip the threads or damage and scratch the screw
heads.

Mount the side panels, using five 3/16” (4.8 mm) flat head screws in each panel. The center top hole will be

filled when you install the top cover later. Although the panels are identical, they only fit one way so the holes

align with the fasteners. If a screw binds or does not line up properly, loosen the other screws holding the 2D

fastener or the screw into the L- bracket so it can move slightly for better alignment. If a side panel seems

pushed away from the bottom cover at the center, check the L-bracket carefully. The usual cause is an L-bracket

installed incorrectly (see Figure 10).
