UNPACKING
Cartridge mounting screws, counterweight, and
hinges for dustcover are packed inside the
styrofoam molding. Platter and rubber mat are
packaged separately and placed beneath the
body of the unit.

AND RUBBER MAT
POWER SUPPLY CONNECTION
For power the unit requires normal house-
hold current (AC). Simply plug the unit into a
wall outlet, or your amplifiers (or receiver's)
convenience receptacle on the rear panel. If it
is plugged to a convenience receptacle marked
“SWITCHED,” you cannot operate the unit
when the power switch on the amplifier or
receiver is set to OFF,
Note: The unit has been factory-adjusted to the
voltage of area it is shipped to. As a precau-
tion, however, locate the Voltage Selector

N
(120V/220-240V) on the upper side of the
unit, and check to be sure the selector is set to
the voltage of your area. If it is not, change the
selector position, using a screwdriver.
INSTALLATION
To prevent hum, do not place the unit near
appliances with motors or large transformers.
Be sure the unit's location is not subject to
high temperature, humidity, or direct sunlight,
to prevent possible troubles.
Vibration or tilted installation will impede
good performance of the turntable and the
stylus will skip grooves.

EXCLUSIVE NOTE FOR U.K,
If your unit comes with a 2-core cable
without a plug, make certain live and
neutral leads are connected to the proper
terminals. Check that the terminals are
screwed down firmly and no loose strands
of wire are present,
IMPORTANT: The wires in this mains lead
are coloured in accordance with the follow-
ing code:
BLUE: NEUTRAL
BROWN: LIVE
As the colours of the wires in the mains lead
of this apparatus may not correspond with
the coloured markings identifying the
terminals in your plug proceed as follows.
The wire which is coloured BLUE must be
connected to the terminal which is marked
with the letter N or coloured BLUE or
BLACK. The wire which is coloured
BROWN must be connected to the terminal
which is marked with the letter L or colour-
ed BROWN or RED.
CARTRIDGE INSTALLATION
The unit accepts a cartridge of 3 - 9 grams
weight. Install an appropriate cartridge onto
the headshell, using the screws, nuts, and
washers supplied for that purpose, If these
screws do not fit your cartridge, use screws
accompanying the cartridge or obtain the
proper ones commercially. The lead wires ex-
tending from the headshell are color-coded, as
listed below. Be sure to connect each wire cor-
rectly.

1. The motor section of the unit is tem-
porarily secured with 2 transit screws to pre-
vent vibration or shock damage during transit.
Using a Philips-head screwdriver, remove these
screws. Keep the screws with the owner's
manual and use again when transporting the
unit in the future.
2. Hold the platter with the plane side up,
and fit the spindle through the platter center
hole to attach to body.
3. Turning the platter by hand, locate the
pulley through one of the holes in the platter.
Hook the attached rubber belt onto the pulley.
Note: On this unit, change r.p.m. (33-1/3 or
45) by manually rehooking the rubber belt.
For 33-1/3 r.p.m., hook the belt onto the upper
groove of the pulley so that the belt runs above
the belt guide; for 45 r.p.m., hook the belt onto

the base of the pulley so that the belt runs
below the belt guide. After hooking the belt,
manually rotate the platter 2 to 3 turns, and
the rubber belt will fit into the pulley smooth-
ly.
CONNECTION TO AMPLIFIER OR
RECEIVER
The unit is provided with RCA cords for both
channels, and a ground wire. The RCA cord
with white plug should be connected to L (left

OVERHANG ADJUSTMENT
* Use a rule, etc. to carry out correct adjust-
ment.
As shown in the illustration, overhang indicates
the distance from the stylus tip to the center of
the turntable spindle when the stylus tip falls
on the extension of a straight line from the
pivot of the tonearm to the center of the spin-
dle. If the overhang adjustment is not properly
made, the stylus will not be able to trace the re-
cord grooves correctly.

dl
1. Loosen the two cartridge mounting
screws.
2. Position the tonearm over the spindie.
3. Slide the cartridge forward or backward
until the position of the stylus tip corresponds
to the specified distance from the center of
spindle (see illustration).
4. After obtaining correct overhang, tighten
the two cartridge mounting screws firmly.
Note: Be careful not to touch stylus during
adjustment with fingers.

STYLUS FORCE ADJUSTMENT
Appropriate stylus force must be obtained to
let the stylus trace the grooove correctly. Incor-
rect setting of the stylus force may cause the
system to skip grooves or affect the reproduced
sound quality,
1. Set the antiskating knob to O position.
Lower the cueing stick, and release the tone-
arm from the arm rest.
2. Move the counterweight forward and
backward so that the tonearm will be balanced
horizontally. When balanced, the headshell is
raised and the tonearm parallels the main body
with the tonearm base as fulcrum. (Caution:
Be careful not to drop the stylus or hit it
against the platter or other objects.)
3. Return the tonearm onto the arm rest.
Turn the gauge ring of the counterweight so
that 0 point falls on the reference marker on
the tonearm.
4. Turn the counterweight to preset the
reading on the gauge to the designated stylus
force of your cartridge. Do not touch the gauge
ring, as it will turn with the counter weight.
5. Turn and set the anti-skating knob to the
value same as the stylus force of your cartridge.
Stylus force adjustment is now complete.
PLAY
1. Make sure the rubber belt is hooked
onto appropriate position on the pulley for the
r.p.m. of your record (see “note” in step 3 of
ASSEMBLY section).
2. Place a record on the platter. To play a
record with a large center hole, use an EP
adaptor commercially available.
3. Free the tonearm from the arm rest
clamp.
4. Swing the tonearm to correct position
over the record. At this moment, the power in
the unit is turned on, and the platter begins to
rotate.
5. Swing the tonearm to correct position
over the record.
6. When the record is over, or when you
wish to interrupt the play midway through the
3
record, lift the cueing stick. Return the tone-
arm to the arm rest, and secure it with the arm
rest clamp. The power inthe unit is automatical-
ly shut off, and the platter stops turning.
MAINTENANCE
1. Keep the stylus tip clean of dust. Clean
the stylus carefully using a soft brush, and
also clean the record before commencing play.
2. The stylus tip is very sensitive. Be careful
not to touch it with a finger nor let it come in
contact with solid objects.
3. The stylus is usually good for about 500
to 1,000 hours of continuous playing. A worn
stylus will cause the record to be distorted and
the record to be damaged. Be sure to use the
correct replacement stylus matching your
cartridge.
4, Do not move the turntable when it is
operating.
Never try to stop the platter forcibly by hand
while it is rotating.
5. When replacing cartridge or stylus, make
sure the power cord is unplugged.
6. Lubrication is unnecessary. Consult your
dealer if necessity arises.
7. Always keep the unit clean. Use a soft
dry cloth to clean the cabinet and the dust

8. The rubber belt conveying rotation of
the pulley to the platter will become stiff or
loose over a long period of use. When that
HOWLING AND HUM
Howling is. usually caused by vibration of
speakers, which affects the sensitive cartridge.
If such a phenomenon occurs, relocate the turn-
table or speakers as far apart from each other as
possible. Hum is usually caused by nearby
appliances that use transformers or thermostat.
Relocating the unit further away from the noise
sources will readily solve the problem.
A hum may also be produced if the unit is not
properly grounded. Make sure the grounding
wire extending from the unit is securely con-
nected to the GND (or G) terminal on the
amplifier or receiver.
happens, consult your dealer and replace
the belt.
