contact. (Fig. 7)
14- 4 Remove the twenty-one (21) screws marked as [140],
then remove the black keys from the lower notes.
Afterwards, remove the white keys DFA and C’ and
then remove the white keys CEGB from the higher
notes. At this time, lift the keys from the front and slide
them towards you. The keys can be removed from the
assembly. (Fig. 8)
15 Assembling the keyboard assembly
15- 1 Install the white keys CEGB from the lower notes, and
then DFA keys and C’ key. Afterwards install the back
keys from the higher notes, and tighten the twenty-one
(21) screws marked [140]. (Fig. 8)
15-2 Install the rubber contacts in the assembly while
pressing the keys as shown in Figure 9. Check that the
rubber contact has been firmly placed into position in
the area indicated by the arrow in Figure 10.
5K When fitting the rubber contacts, raise both ends of the
frame so that keys do not push the rubber contact up.
Install the MK circuit board in the assembly so that the
hooks (B) hold it as shown in Figure 11.
