Replacement Switches
As areplacement for old and new type switch contacts,
amatrix board of new type switches only is available.
Replacement of individual switch is not recommended.
Changing to new type switch contact needs exchanging

CAUTION
When ordering, state the serial number of agiven unit to
allow the factory judge whether revised ROM Ato be

(1) TUNE DATA (1)
Atuning data updated by TUNE button and the alpha TUNE 4^' ^yi: 0^ ^—^'y
dial is stored into the backed up RAM (IC26) on CPU-A
board. The setting is non-volatile, that is, it is retained in —CPU—ASI^CD RAM IC265Cs5'fi:^ TL^
memory even after the unit is turned off.
RiD-IOOO
With Ver. 1.3
On power-up the tuning data is not transferred from the
RAM to CPU-B board which controls voice reproduction
including pitch, resulting in the following phenomena to
appear.
1.The pitch of the Aabove middle Cis 442Hz when the
unit is switched on —regardless of the previous
tuning.
2. Pressing TUNE will display the previous pitch, e.g.
438.0Hz.
3. Rotating the alpha dial will cause the pitch to jump
from 442Hz (on the A) to 438.0Hz +aHz (pro-
portional to the dial turning).

With Ver. 1.4
The RAM-stored tuning data is delivered to the CPU-B
board upon power-up. The modules are ready to sound
at the pitch set before the previous power off —no
descrepancy between the display reading (TUNE pres-
sed) and the actual pitch.
(2) KEYBOARD SWITCH
For more positive contact of the keyboard switch,
change its contact combination as shown in the table
above. Sensitivity to akey touch differs between the
two types. This leads to arevision of ROM Ato change
key touch response of the subsequent stages.
When akey(s) needs replacing, replace agroup(s) of
switches with akeyboard matrix board(s) having the
new type switches.
Exchanging old type switches with the new ones requires
ROM Aof Ver. 2.1 or up.
When ordering, specify whether the existing switches are

1. Remove screws ^(8 pcs) and grounding lugs ^(4
pcs).
2. Key Lock Levers

1. Before removing, repeatedly lock and unlock alever
to sense the degrees of mechanical reaction force of
the lever. Recall this friction when reassembling the
levers later.
2-2. While holding alever with one hand, remove nut ©
and washer; pull down the lever through the key-
board together with the Tension Rod. Similarly,
remove the other lever.

4-2. Completely loosen screws Q{5 pcs).
4-3. Remove screws @(5 pcs); lift up Switch Chassis
(R) and rest it against the back of Back Rail ©.
Now the keys are ready for removal.
Reassembling Keyboard
Although the reverse steps of the above procedure seems
effective to reassembly, there are some cautions to be
observed for satisfactory keyboard performance: follow
the instruction below.
1. Matrix Boards
1-1. Place and loosely install Switch Chassis ®with
screws Q)

1.Secure Lock Bar on both ends with screws ©and
washers.
2-2. Recap cushions ©.

hole.
3-2. Loosely nut ©on Lock Bar.
3-3. While locking and unlocking Lever, tighten the nut
to have Lever the appropriate tension against un-
locking force. (See 2-1 in Removing section.)
3-4. Similarly, install the other Lever. Adjust ©so that
Rod tension equals that in step 3-3.
3-5. Apply few drops of paint, lacquer or adhesive to
nuts ©,washers and Lock Bar top for loose-proof.
