Figure 3.5
(Refer also to Figure 3.6 on the following page.)
While holding the top cover securely, tilt it up and
back as shown in the above illustration. Be sure to place
the the top cover on a soft surface.
Disconnect the cable from J14 on the Engine Board. J14
connects the Mod Wheel Assembly to the Engine Board.
Locate the shield to the left of the top cover. Remove
the 5 Phillips head screws along the rear panel edge of the
shield and fold the shield back. Refer to Figure 3.2 for
orientation.
On the Engine Board, located to the left of the top
cover, locate the flat ribbon cables at locations J5 and J6
(both at far left edge of board). J5 is the Keyboard Bass
cable and J6 is the Keyboard Treble cable. The cables are
secured with clear tape or a clip, simply pull the tape back
or remove the clip and disconnect the cables. Feel free to
make a mark on one of the keyboard cables and its
associated connector so that the Bass and Treble are not
reversed when reconnecting.
The top cover is now completely separate from the
unit. If you are not working with any of the circuitry
contained on the top cover, place if safely out of the way.
