1. Remove all of the keys from the key frame.
Note: Be certain to paint the keys before replacing them in the piano. See
Figure 21
on page 16.
2. Place the Key Scan Assembly on the key frame as shown in
Figure 15.
3. Obtain the Key Scan Track Mounts from the kit and position them under the track and directly on top of
the vertical slats of the key frame.
4. Align the metal track into the recess of the plastic track mounts and attach the mounts “loosely” to the
track using the 4-40 x 1/4 pan head screws.
See figure 16.
We will tighten the screws once the exact bass to treble position is determined.
5. Move the Key Scan Assembly, front to back, to align the row of Optical Sensors with the two marks
made on the bass and treble ends of the key frame.
Figures 15 & 17.
6. Use the provided 4x3/4” screws to fasten the mounts to the wood key frame.
Later we will loosen these screws to add shims between the mounts and the key frame to set the proper
Key Scan Assembly height and angle.
7. Place keys 33 & 34 on the key frame.
8. Slide the Key Scan Assembly, bass to treble within the track mounts, so that the mark on the tape
(
Figure 14
) is centered in the space between keys 33 & 34.

.
9. Tighten the screws to secure the Key Scan Assembly to the Track Mounts.
10. Remove the masking tape from the “Status” LED between keys 33 & 34.
