be
careful
not
to
let
the
stylus
contact
the
turntable
mat
or
base.
4. After balancing the tonearm, clamp the tonearm into the
arm rest.
5. While holding the counterweight stationary, rotate the
weight ring so that the “0” on the ring scale is lined up
with the center line on the tonearm shaft. (Fig. 6)
This completes tonearm balancing (horizontal zero
balance).
6. Turn the counterweight in the direction of the arrow so
that the weight ring shows the correct stylus pressure
number lined up with the center line. (Fig. 7)
(Follow the cartridge manufacturer's recommendation.)
When the counterweight is turned, the weight ring moves
with it. Stylus pressure is indicated by the number on the
scale aligned with the center line.
Note:
Set the stylus pressure to the maximum recommended
value for your cartridge in cases where the record has an
extremely high recording level, or where the unit is
operated in a room at low temperature, or in places in
which the unit is subjected to vibrations.
@ Adjusting the anti-skating control (Fig. 8)
Set
the
anti-skating
control
to
the
same
value
as
the
stylus
pressure.
Note:
When a cartridge with integral dust brush is used, follow
the cartridge manufacturer's recommendation for adjust-
ing both stylus pressure and anti-skating control.
@ Attaching the dust cover (Fig. 9)
Hold both sides of the cover and lower it into the hinge
slots. To remove the cover, open it and pull upward.

reason.
OPnao wo
MN
H Stopping the turntable
Push the stop switch. (Fig. 14)
The tonearm will return to the arm rest and the turntable will
stop.
@ Temporarily interrupting play
Set the cueing control to the “¥” position.
This will make the tonearm rise off the record.
@ Playing 45-rpm records having large center
holes
Put the 45-rpm adaptor over the center spindle. (Fig. 15)
Push the speed selector for 45 rpm (=).

@ Arm-lift height adjustment
The arm-lift height (distance between the stylus tip and
the record surface when the cueing control is at the “¥”
position) has been adjusted at the factory to approximately
5 mm (3/16"), (Fig. 16)
If the clearance is too narrow or too wide (because of dif-
ferent cartridge dimensions, for example), turn the adjust-
ment screw clockwise or counterclockwise. (Fig. 17)
Clockwise rotation
—distance between the record and stylus tip is decreased.
Counterclockwise rotation
—distance between the record and stylus tip is increased.

(Remove the rubber cap.)
1, Put the stylus protector on the cartridge.
2. Remove the tonearm toward the center of the record.
Then, the auto-return adjustment screw will appear.
If the tonearm tends to return to the arm rest before
play has finished,
—turn counterclockwise.
If the tonearm fails to return after the final groove,
—turn clockwise.
Speed adjustment (pitch control) (Fig. 19)
There are strobe-lines cut on this turntable platter to indicate
correct rotational speed.
If the strobe-line appears to be moving as the turntable
rotates, adjust while playing a record
1. Push the speed selector of the speed to be adjusted.
2. Watch the dot pattern on the side of the platter. Turn the
pitch control one way or the other until the dots appear to
stand still. This is the correct speed.
3. Turning the pitch control in the “+” direction increases
the speed.
4. Turning the pitch control in the “—” direction decreases
the speed.
Note:
Strobe dot pattern
This unit’s strobe illuminator operates at the AC line
frequency which generally has a 0.2% fluctuation.
This fluctuation, when present, may make the strobe
pattern appear to change. However, actual turntable
speed does not change, because the DC motor is not
affected by AC power line frequency.
Stylus replacement and
cartridge installation
@ Stylus replacement (Fig. 20)
The replacement stylus for this cartridge is EPS-25CS.
Replace the stylus at the first sign of wear or after about 1000
hours of use. Correct stylus pressure (tracking force) and
proper record and stylus care will help extend stylus life.
Stylus life varies with the conditions of use.
Noise or scratchiness may indicate a worn or damaged
stylus.
To avoid damaging records, do not use a stylus that seems
worn. Replace it immediately.
1. Loosen the tonearm locking sleeve to remove the head-
shell and cartridge.
2. Hold the headshell with the cartridge facing up. With your
other hand, grasp the stylus assembly and pull out and up
at a slant.
3. Line up the new stylus assembly with the cartridge and
push in firmly as far as it will go.
™ Cartridge installation (Fig. 21)
When installing a cartridge, follow the instructions that came
with the cartridge.
1. Connect the lead wires to the cartridge terminals.
The terminals of most cartridges are color coded. Con-
nect each lead wire to the terminal of the same color.

2. Mount the cartridge in the headshell using the screws
provided with the cartridge.
@ About cartridge weight: (Refer to page 1)
Cartridges weighing between 3.5 and 7.5 g can be used on
this tonearm.
If you purchase the optional auxiliary weight (Part number:
SFPWG17202), or shell weight (Part number: SFCZB30505),
cartridges weighing up to 10.5 g can be used.
Note:
Attach the shell weight between the headshell and the
cartridge.
Attach the auxiliary weight to the rear end of the
tonearm.
When attached, the auxiliary weight bumps against the
dust cover, so remove the cover during play.
@ Overhang adjustment (Fig. 22)
15 mm is the correct overhang for this tonearm.
Loosen the screws and move the cartridge forward or back-
ward until the distance between the stylus tip and the plug
becomes 52 mm (2-3/64").
Tighten the screws without moving the cartridge.
Adjust the horizontal zero balance, stylus pressure and arm-
lift height whenever you change the cartridge.

Notes and maintenance
@ Do not touch or hold the tonearm during automatic opera-
tion.
@ Avoid pressing on the platter while it is rotating.
Do not try to hold it stationary.
@ Be careful when using differently shaped headshells.
(Fig. 23)
With some headshelis, the finger grip may strike the dust
cover during automatic operation. Should this occur, leave
the cover open during play.
@ Before detaching or attaching a headshell, be sure to turn off
the power on the amplifier or receiver.
Speakers may be damaged if a headshell is attached or
detached when the volume is turned up.
HF Carefully remove dust and dirt from records and stylus.
Dust and dirt degrade sound quality and cause excessive
wear of the stylus and grooves.
BB Wipe the headshell terminals from time to time. (Fig. 24)
Dirty terminals can cause noisy reproduction. If severe,
there may be no sound atall. Use a soft dry cloth to clean the
headshell terminals.
@ Wipe the dust cover and turntable base with a soft, dry cloth.
Never use volatile cleaners such as alcohol, benzine or
thinner.
Do not use chemically treated dust cloths. Do not expose the
cover to insecticide spray.
To remove stubborn spots, first pull out the AC plug and
detach the cover.
Then wipe the cover with a soft cloth slightly moistened with
a mild soap and water solution.
Do not wipe the cover during play, or the tonearm may be
attracted toward the cover due to the generation of static
electricity.
