NOTE
This
is
the modification
in
circuit. Please make necessary
treatment for unmodified
sets.
(1)
Please fix yellow
KBD
wires
to KBD
chasis with
cord
keeper in order to keep the wires away from
IC33 on
PC-Board
KLM-367. This
modification prevents
wrong operation of the programmer.
(2)
Connect the
GND
side of the battery on P.C. -board
KLM-367 to GND
No. R2, R3
and
R4
on
P.C.
-board
KLM-370.
(3)
CONNECT the GND of PHONE
JACKS to
shield
sheet under KLM-368.
(4)
Modifucation
to
improve the higher frequency
re-
sponse has been made on KLM-368 in order
to
im-
prove the tone quality from the June production.
The circuit
diagram
in this manual
fits for
the modifi-
cation.
Constants
for
the
old production are
as follows:
R167 2.2KJ2 R166
1K£7
R197

K£2 C78
0.0047£i
R196 100

The circuit diagram and
the P-C Board for KLM-366
have
been modified from
the June
production.
Accordingly, adjustment
procedure
for
KLM-366
has
been changed
as
follows:
1)
VCF
for adjustment (Change
in R58 and R64)
Turn CUTOFF from 0
to 10 and
check to see that
each unit's oscillation
frequency is
6.5~20
Hz
at
0
and
25~31
KHz at 10.
Amplitude should
be
at
least
300mVp-p throughout.
2)
KBD
TRACK offset
adjustment
Same
setting as
p21 (6)
Play
Cl
and turn the
KBD
TRACK
knob
from
0 to 10.
Confirm that the
difference between these
two
pitches is within
20
cents.
If
not,
adjust VR-13.
3)
PITCH check and adjustment
VR15
on KLM-366 is equal to VR1
on
KLM-396.
Confirm that difference between
4'
D#4
and E4
is within
2
cents.
If
necessary, adjust VR14.
VR2
is used
to
adjust for deviation
in higher pitch
range totally for all the
6
units.
OUTPUT AND LEVEL
adjustment
Same
setting
as
P23
(4).
Play
C3
and adjust VR8
to obtain a sawtooth
wave-
form, amplitude
of
2.0Vp-p
(±5%).
