Replacing the Keyboard Assembly
Note: Before proceeding, verify that the Keyboard Assembly cables are connected (Bass and
Treble at ribbon cables and the at ex cables connecting the Keyboard Contact PCBs).
1. Place the Keyboard Assembly on the bottom enclosure. Make sure the Bass and Treble
at ribbon cables are visible.
2. Slide the SP5-8 bottom enclosure forward so that the front edge hangs over your work
surface. Install the six front screws. Slide the SP5-8 back on to your work surface.
Caution: Step 3 instructs you to lift the back edge of the SP5-8 up to access the three screws
that secure the back edge of the Keyboard Assembly. You should be in position at the front
edge of the SP5-8 to provide added support and protection with your body.
3. Slide the SP5-8 toward the middle of your work surface (away from the front edge).
While continuously supporting the SP5-8, tilt the SP5-8 up and install the three screws
securing the back edge of the Keyboard Assembly to the bottom enclosure, then lay the
