d. Apply slight pressure to the back end of the Lo Contact PCB. Doing so, lowers the
PCB so that it is laying at on the keyboard chassis.
e. Make sure the alignment posts are positioned through the holes provided for them
on the Lo Contact PCB.
Caution: If you need to reposition the PCB, be careful you do not dislodge or damage the
keyboard contacts.
f. Install the 11 screws to secure the Lo Contact PCB to the keyboard chassis. While
doing so, include the small at plate that connects the Lo and Mid Contact PCBs.
Install the screw to secure the small at plate on the Mid Contact PCB.
3. Insert the at ex cable from the Mid Contact PCB into the connector on the Lo Contact
PCB.
Removing the Mid Contact PCB
1. Disconnect the at ex cables that connect the Mid Contact PCB to the Lo and Hi
Contact PCBs. Gently tug on the at ex cables to disconnect them.
2. Disconnect the at ribbon cables from J6 (Bass) and J7 (Treble) on the Mid Contact PCB.
Should the at ribbon cables have tape securing them to the contact PCB, peel back the
tape from one side so that the tape remains properly positioned.
3. Remove the ten screws that secure the Mid Contact PCB to the keyboard chassis.
4. There is a small at plate connecting the Mid to the Lo Contact PCBs. Two screws secure
it. The screw on the Mid side is one of the ten screws described in Step 3. The second
screw is on the Lo Contact PCB. Remove the screw from the plate on the Lo Contact PCB
and set the plate safely aside.
5. Carefully lift and remove the Mid Contact PCB.
Replacing the Mid Contact PCB
1. Position the Mid Contact PCB over the keyboard chassis. The at ex cable connector
and the keyboard diodes should be positioned closest to the back of the keyboard
chassis.
2. Refer to Figure 4-21. In addition to the ten screws that secure the Mid Contact PCB to the
keyboard chassis, there are tabs and alignment posts on the keyboard chassis that help
secure and correctly position the Mid Contact PCB.
a. Angle the PCB so that its front edge is positioned under the tabs and align the screw
holes in the PCB over their location on the keyboard chassis.
b. Apply slight pressure to the back end of the Mid Contact PCB. Doing so, lowers the
PCB so that it is laying at on the keyboard chassis.
c. Make sure the alignment posts are positioned through the holes provided for them
on the Mid Contact PCB.
