Removing the PC2X Keyboard Assembly
The following procedure assumes that the PC2X is open and that you have followed the
instructions to remove the top enclosure.
1. The keyboard is secured to the bottom enclosure using ten screws. Refer to Figure 4-16 for
the position of the screws. Arrows identify the locations of the ten screws.
2. Tilt the PC2X up and remove the five keyboard rear screws, then lay the PC2X flat on your
work surface.
3. Move the PC2X forward so that the front hangs over the edge of your work surface to
access the remaining screws, and remove the five keyboard front screws.
4. Remove the four Mod Wheel screws and washers. At this point the keyboard is loose in
the bottom enclosure, but it has cables connected to the Mod Wheel Assembly and the
Connector Board.

5. Slide the PC2X back onto your work surface.
6. Lift the Mod Wheel Assembly and disconnect the Aftertouch flex cables. These cables
have nylon reinforced tape securing them to the bottom enclosure. Peel back the tape from
one side to free the cables.
7. Place the Mod Wheel Assembly in its position on the bottom enclosure.
8. Remove the cable locking clips and disconnect the flat ribbon cables from locations J306
and J307 on the Connector Board. These cables are also secured to the bottom enclosure
with nylon reinforced tape. Peel back the tape from one side to free the cables.
Note: If you are merely replacing one or more keys, it is not necessary to entirely remove
the Keyboard Assembly from the PC2X. Follow the procedure on page 4-27.
