e Arm-lift height adjustment
The
arm-lift
height
(distance
between
the stylus tip and
record surface when the cueing control is set to the " VV"
position) has been adjusted at the factory to approximately
5 mm (3/16"). (Fig. 10)
If the clearance
is too narrow
or too wide
(because
of
different
cartridge
dimensions,
for
example),
turn
the
adjustment screw clockwise or counterclockwise.
(See Fig. 11)
Clockwise rotation
—distance
between
the record and stylus tip is decreassed.
Counterclockwise rotation
—distance
between
the record and stylus tip is increased.
e Adjustment of automatic return position (Fig. 12)
1. Put the stylus protector on the cartridge.
2. Take off the rubber cap covering the adjustment screw
section and move the tonearm toward the center of the
record.
Then,
the
auto-return
position
adjustment
screw
will
appear.
If the tonearm tends to return to the arm rest before the
play has finished,
—turn counterclockwise.
If the tonearm fails to return after the final groove,
—turn clockwise.
e Overhang adjustment (Fig. 13)
15 mm is the correct overhang for this tonearm.
Loosen
the
screws
and
move
the
cartridge
forward
or
backward
until the distance between the stylus tip and the
plug becomes 52 mm (2-3/64"').
Tigthen the screws without moving the cartridge.
Adjust the horizontal zero balance, stylus pressure and arm-
lift height whenever you change the cartridge.

e Adjustment of rotational speed
After replacement of drive IC (1C101) and variable resistors
(VR202,
203) or when the rated speed is not obtained by
tuning
the
pitch
control
knob,
perform
the adjustment
according to the following procedure.
1. Remove
the bottom
board.
(Refer to "Disassembly
Instructions"'.)
. Place the set on the player repair table.
. Put on the record and play.
. Push the speed selector button to 45 r.p.m.".
. Turn the pitch control knob to central position.
(See Fig. 14)
. Adjust VR202
by the screwdriver from under the set
until the rated speed (45 r.p.m.) is obtained while check-
ing it through the stroboscope.
(See Fig. 15)
. Push the speed selector button to "33 r.p.m.".
8. Adjust VR203
by the screwdriver until the rated speed
(33-1/3
r.p.m.)
is obtained
while
checking
it through
the stroboscope.
(See Fig. 15)
9. After
completing
the
above-mentioned
adjustment,
check that the rated speeds can be obtained by pushing
the speed selector button.
Note:
Be sure to perform the adjustment of 45 r.p.m. first.
10. As a simple method, it is also possible to adjust VR202
and VR203, removing the turntable.
