PC2/PC2X Disassembly/Assembly
Top Enclosure
The LCD is mounted onto a bezel that is secured to the Front Panel Board with small pegs
that snap into holes on the Front Panel Board. Removing the LCD requires cutting the tie
wraps that bundle the LCD cables to cable mounts positioned along the rear panel. It is
not necessary to remove the LCD from the unit. Remove the four screws that secure the
LCD to the front panel bezel. Lift the LCD up from the bezel and fold it over so that the
circuit side of the LCD is positioned above the Slider Board. For protection, place a piece
of anti-static material between the LCD and Slider Boards.
8. Lift the Front Panel Board up from the top enclosure. The spinknob and switch button
caps should remain in place.
Caution: Each switch button cap uses a set of small pegs to mount the cap to the Front
Panel Board. The button caps are mounted individually or in clusters. If a cap becomes
separated from the board, be careful that a peg is not inadvertently broken.
Replacing the Front Panel Board
1. Position the Front Panel Board onto the top enclosure, then raise the top enclosure up
slightly to verify that the spinknob and switch button caps are correctly positioned
through their openings in the top enclosure.
2. Align the center screw holes of the three-hole groupings on the front panel edge of the
board with the thread marks in the extrusion and install the two screws that secure the
front panel edge. See Figure 4-8.
3. Place a PC board clamp in position. Align the center screw holes of the clamp with the
thread marks in the extrusion and install the two screws that secure the clamp. Repeat for
the other two clamps.
4. Position the LCD onto the front panel bezel and install the four screws that secure it to the
bezel.
5. Connect the wire trap flat ribbon cables in the following order.
Caution: Be sure to look for the marking on the edge of the cable denoting Pin 1 and that
you match it correctly with Pin 1 on the board. Make certain that the wires are straight
prior to inserting them into the connector and that each wire is correctly inserted into its
respective position.
Note: Be sure the sides of the connector are lifted. Insert the flat ribbon cables into the
wire trap connectors and push down the sides of each connector to lock the cable into the
connector. Gently pull each cable to verify that it is locked into its connector.
Insert the five-wire flat ribbon cable from the Button Board into the wire trap connector at
J601 on the Front Panel Board.
Insert the eight-wire flat ribbon cable from the Slider Board into the wire trap connector at
J602 on the Front Panel Board.
6. If you have disconnected the flat ribbon cable from J604, reconnect it. Be sure to install the
cable locking clip.
7. Follow the procedure on page 4-10 to install the Connector Board.
8. Follow the procedure on page 4-8 to install the right enclosure support wall.
