10. ADJUSTMENTS
10.1 AUTO-RETURN ADJUSTMENT
@ Auto-Return Position Adjustment
When auto-return occurs too early or too late,
make the following adjustments.
1. Check the stylus landing position. If the stylus
does not land at the correct position, adjust the
landing position.
2. Set the arm elevation switch to UP and turn
the auto-return adjustment screw fully counter-
clockwise.
3.Move the tone arm as far as it will go
toward the inside.
4. When the auto-return adjustment screws is
turned slowly clockwise, the tone arm will
begin to move toward the inside.
5. Stop turning the adjustment screw at the point
at which there is a space of 32mm between
the cartridge stylus and the center shaft. (Fig.
10-1)
6. After adjustment, check is auto-return is per-
formed correctly and that the stylus landing
position is correct.
10.2 MECHANISM ADJUSTMENT
@ Stylus Landing Position Adjustment
When the tone arm doesn’t land in the correct
position during automatic playback, adjust
according to the following procedure.
1. Place a 30 cm record on the platter.
2. Press the START/STOP switch and start auto-
matic playback. Note the direction and amount
if the landing point is off. (How many mm to
the inside or outside from the record grooves.)
3. Depress the START/STOP switch to return the
tone arm to its rest.
4. Press the arm elevation switch to raise the
stylus.
5.
Move
the
tone
arm
to
the
outside
edge
of
the
record
by
hand.
6.
Turn
the

according
to
the
direction
and

When
the
stylus
lands
at
the
inside
of
the
record,turn
the
adjustment
screw
in
the@
direction.
One half turn of the adjustment screws
moves the tone arm about 12 mm.
7. After adjustment, press the PLAY/STOP
switch and check if the stylus landing point
was correctly adjusted.
If adjustment is incorrect, repeat items 3 to 6.

10.3 ARM-ELEVATION ADJUSTMENT
@ Arm Elevation Height Adjustment
1. Depress the arm elevation switch to lower the
arm.
2. Adjust the screw under the turntable so the
stylus is 11mm above the panel. When the
adjustment screw is turned counterclockwise,
the stylus rises.
3. Depress the arm elevation switch to raise the

2. Presionar el interruptor START/STOP (arran-
que/parado) y efectuar la reproduccion automa-
tica. apuntar la direcciOn y la cantidad si el
punto de descanso esta descentrado. (Distancia
en mm hacia dentro o fuera desde las ranuras del
disco).
3. Presionar el interruptor START/STOP para
regresar el brazo sonoro a su descanso.
4. Presionar el interruptor de elevacién del brazo
para levantar la aguja.
5. Desplazar manualmente el brazo sonoro hacia el
borde exterior del disco.

11. PRECAUTIONS FOR REASSEMBLY
Follow these directions and precautions when
reassembling a unit after completing repairs. Be
sure to lubricate as required, make no mistakes
when attaching parts, and avoid all other careless
mistakes that may be the cause of trouble later on.
11.1 AREAS THAT REQUIRE LUBRICATION
NOTE:
Types of lubricants and areas where they are used are
listed in table 1.
Table 1
Type of Oil Areas used
Silicon Oil #50000 raising shaft
Lubrication points are specified for oils other
than GYA-008. Never use a different type of oil.
e Cam Section
Apply grease to the heart-shaped grooved section
(rear side of the cam) and lock plate sliding section
in order to minimize wear on the sliding section
and the burden on the mechanism.

Apply grease to the switch locker (opening) and
sub-panel base sliding section to decrease the
burden on the mechanism.
When applying grease to the opening (shaft hole),
do not apply any grease 2 ~ 3mm from the bottom
surface. If grease is applied 2~3mm within the
bottom surface, it may come out the bottom and
go between the switch lever and sub-panel base
causing the switch lever to operate ineffectively.
