Installing the Control’s Circuit Board

To install the circuit board in the cabinet, perform the following steps:

Step Action

1Hang the three mounting clips on the raised cabinet tabs. Refer to Figure 3-3(Detail B).

Make sure the clip orientation is exactly as shown in the diagram to avoid damage. This will also avoid problems with insertion and removal of the PC board.

2Insert the top of the circuit board into the slots at the top of the cabinet. Make certain that the board rests in the slots as indicated (Detail A).

3Swing the base of the board into the mounting clips and secure the board to the cabinet with the accompanying screws.

Notes:

•Make certain that the mounting screws are tight. This ensures that there is a good ground connection between the PC board and the cabinet.

•Dress field wiring away from the microprocessor (center) section of the PC board. Use the loops on the left and right sidewalls of the cabinet for anchoring field wiring using tie wraps (Detail C). These steps are important to minimize the risk of panel RF interference with television reception.
