© Compatibility between SK-6L and SK-
6 Keyboard
KR-4500 use the new type keyboard SK-6L.
Please note that the SK-6L type and SK-6 type
keyboards use incompatible parts each other.
The explanation of differences (or similarities) between
the SK-6L and SK-6, is organized according to three
categories.
Parts A: parts specially for the SK-6L
Parts B: parts used even for the SK-6 but modified
to use for SK-6L
Parts C: parts used even for the SK-6 and used for
SK-6L as it is too
For details, refer to the below.
Now, the procedure to remove or to assemble the key
of SK-6L and SK-6 are different each other.
About the SK-6L, when remove the white key and black
key that is adjacent each other, it is necessory to remove
the white key before the black.
When mount the white key and the black key that is
adjacent each other, it is necessory to mount the black
key before the white.
it is impossible to do with contrary procedure. But, about
the SK-6, either procedure will do.

© Rubber Switch for Keyboard
About rubber switch for keyboard, rubber contacts for
natural-key (white key) and sharp-key (black key)
are made by different dimensions.
The height of rubber contacts is different as shown
below.
When replacing rubber switch, attach it to the place
matching characters (tone name) with keys.
When cut the rubber switch, you should cut it at grooved
line.
NOTE :
Replacement PCB ASSY are equiped with rubber switch,
but a rubber switch are also available as separate
replacement.
