Keyboard Assembly Procedure
How to Install the Contact Circuit Board
The service-use contact circuit board (#04567412) is supplied with the rubber switches mounted. To prevent problems with sound
generation due to dust contamination, do not detach the rubber switches.
1. Turn the keyboard chassis upside-down.
2. Peel off the backing paper from the double-sided adhesive tape affixed to the edge surfaces of the contact circuit board.
3. Align the notch in the contact circuit board with the positioning hook on the keyboard chassis, and install the circuit board so that it is
clasped by the clasp hooks.

* If the contact circuit board is warped, tighten while pressing down lightly on the center of the circuit board.
* If using an electric screwdriver, set the screw-tightening torque at 0.8 N. Applying excessive force to the circuit board may damage the pattern and cause
problems with sound generation.
