16. Disassembling the Keyboard Assembly
16-1 Remove the Keyboard assembly. (See procedure 11.)
16-2 Remove the two (2) screws marked [30]. The MKS5F cir-
cuit board can then be removed. (Fig. 2)
* Be sure to make a correct match when connecting
MKS5F (CN1) and DM (CN102).
Connecting the connectors in the wrong way around
may cause damage to the MKS5F circuit board.
16-3 Remove the MK-L and MK-H circuit board while pressing
the fifteen (15)hooks A inward, and then remove the rub-
ber contact. (Fig. 11)
16-4 Remove the twenty-one (21) screws marked [140], then
removw the black keys from the lower notes. Afterwards,
remove the white keys DFA and C' and then remove the
white keys CEGB from the higer notes. At this time, lift
the keys from the front and slide them towards you. The
keys can then be removed from the assembly. (Fig. 12)
17. Assembling the Keyboard Assembly
17-1 Install the white keys CEGB from the lower notes, and then
install the DFAkeys and C' key.Afterwards install the black
keys from the higher notes, and tighten the twenty-one (21)
screws marked [140]. (Fig. 12)
17-2 Install the rubber contacts in the assembly while pressing
the keys as shown in Figure13. Check that the rubber con-
tact has been firmly placed into position in the area indi-
cated by the arrow in Figure 14. When fitting the rubber
contacts, raise both ends of the frame so that keys do not
push the rubber contact up.
17-3 Install the MK-L and MK-H circuit boards in the assembly
so that the hooks B hold it as shown in Figure 15.
