1. Assemble the four Aluminum Key Scan Track sections. See Figure 2 .

Notice that one joint pin protrudes slightly further than the other allowing for easy of alignment into the
joining sections. Slide all sections firmly together.
2. Add a strip of the silver-metal tape across each joint, on the underside of the aluminum tracks, to hold
the sections together.
3. There are 3 cable connectors on each of the Key Scan Circuit Boards. Slide the boards into the tracks so
that the connector closest to the end of the circuit board faces left (bass end). This puts the Optical
Sensors towards the rear of the piano.
These sensors will be aligned with the marks you made on the action
frame and on keys #1 and #88. See Figure 1. The remaining 3 circuit boards need to be placed with the
same orientation. See Figure 3.

There are four pieces of fiber tape attached to the bottom of the boards. This tape will insure a snug fit
into the tracks so the boards won’t slide out of position easily. The tape also helps to eliminate noise
between the boards and the track due to vibration.
 
Hold the boards close to the metal track so the boards don’t bend and break as you insert them.

Locking Verses Non-Locking Cable Connectors
You will see the two types of connectors on the circuit boards; Locking and Non-Locking.

Locking: Figure 4A . Used on type 1 key scan boards. The lock must be fully pulled out prior to inserting
the cable. Once the cable is inserted the lock must be fully pushed in toward the connector.
NOTE: Use care not to force the connector latches when unlocking or locking them as it is possible to break them.

Non-lock: Figure 4B . Only requires full insertion of cable.
