KEYBOARD DISASSEMBLY
<Attaching the RUBBER SWITCHES and PCB>
To fasten the SK-9 PWB,be sure to use 3*10mm BINDING VWH (PART
No.40233545).
1. Turn the chassis over as shown in fig.1.Next,place 4 pieces of RUBBER
SWITCH 12P in turn,on the chassis from the left end(the bass side of
keyboard),aligning them with the long holes provided on the chassis.
At this point,be sure that the air-escape grooves of each RUBBER SWITCH are
positioned at the respective air-escape grooves on the chassis.(See fig.2)
Then on the right side(the high note area),place RUBBER SWITCH 13P in the
same way.

2. Aligning the cutouts in the PWB with the lugs on the chassis,put one side
of the PCB into the chassis hooks.Place the PCB on the Chassis so that the
chassis positioning pins fit into the positioning holes.(See fig.3)At this
point,the chassis positioning reference pin should first be fitted into the
hole.There are two PCBs,LOW and HI,as shown in fig.4.The Chassis
positioning reference pins are located near the connector each of the
LOW and HI PCBs.
