Removing the Keyboard Contact Strips
1. Place the keyboard upside down on a fl at soft surface. Be sure that the keys are resting on
a soft surface to avoid scratching or other damage.
2. Follow the procedure for removing the Bass and Treble Keyboard Contact Boards.
3. Examine the keyboard contact strips and look at the design of an individual contact. The
top portion of the contact has two indentations. One indentation is deeper than the other.
When replacing the keyboard contact strips, the deeper indentation is always positioned
toward the rear of the key.
4. The keyboard contact strips have mounting pegs that secure the contact strips to the
keyboard contact boards.
5. To remove a keyboard contact strip, gently lift and free the strip from its position. Be
careful not to rip or damage any contact in the process.

Replacing the Keyboard Contact Strips
1. Position the contact strip on the Keyboard Contact Board that you are servicing.
Note: Be sure that the deeper indentation is positioned toward the rear of the key.
2. Line up the contact strip mounting pegs with their respective mounting holes on the
keyboard contact board.
3. Using a small blunt-end tool (Q-Tip, toothpick, etc.), gently push the mounting pegs
through the holes. Do not use too much force or use a tool that can poke a hole through
the mounting pegs. However, be sure that the mounting pegs are installed through the
holes.
