Disassembly/Assembly
Replacing the Keyboard Contact Strips
Position the contact strip on the board. Be sure the
deeper indent of the contact is located to the rear of the
key.
The contacts are secured to the board by small and
somewhat larger rubber pegs that are pushed through
their respective mounting holes on the board.
Be sure that the rubber mounting pegs line up
correctly.
Using a small blunt-end tool (i.e. Q-Tip, toothpick,
etc.), gently push the mounting pegs through the holes.
Be careful not to poke through the mounting pegs when
installing the contract strips.
Removing a Key Weight
The PC88 keyboard key weights are attached via a rod
that runs the length of the keyboard. The rod is actually
two pieces. The first rod starts at low A and extends to G#
above middle C. The second rod starts at A above middle
C to High C. These rods will be referred to as the Bass and
the Treble rod.
The natural/white and sharp/black key weights are
physically different. You will notice that the sharp key
weights are somewhat smaller. Be sure to install the key
weights into their appropriate positions after removal.
The main components of the weighted-key action
consist of the following: the keys (88 keys), two rods, key
weights (88), key weight and rod support bracket (7, 12 key-
position and 1, 4 key-position).
To remove a key weight, follow the instructions
indicated to remove the Keyboard. Remove the keys from
the section with the broken key weight.
