requires
no
troublesome
assembly
or
adjustment
procedures,
please
be
sure
to
read
the
sections
in
this
instruction
manual
about
removing

@ Upper cabinet:
Contains tonearm drive mechanism.
@ Record groove scale (1 mm pitch):
This scale is graduated in 1 mm indications. By noting the
position of the tonearm LED you can determine the actual
position of the tonearm in the record grooves.
© Tonearm LED:
This
arrow-shaped
LED
lights
up
when
the
power
is
turned
on
(=),
to show
you
the
position
of the
tonearm
as
it traces
the
record
grooves.
By
following
the
movement
of the
tone-
arm
LED
on
the
record
groove
scale,
you
can
easily
control
cueing
of the
tonearm
to the
desired
point
on
the
record.
O Cartridge
@ Stabilizer/stroboscope:
When the upper cabinet is closed, the stabilizer contacts the
record
label
area
to
keep
the
record
firmly
in
place.
Around
the circumference of the stabilizer is a stroboscope syn-
chronized with the quartz oscillator reference frequency,
so
that
you
can
easily
confirm
correct
rotational
speed
(33-1/3 or 45 rpm).
@ Stop button:
When you press the stop button, an LED (>) lights up
momentarily
and
the
tonearm
automatically
returns
to
the
start position and stops there.
(Auto-return, auto-stop.)
If
you
keep
the
button
depressed,
the
tonearm
will
move
outward
(p>)
toward
the
edge
of
the
record,
Press
harder
and
the
tonearm
will
move
faster
(
>
>).
\f
you
press
the
cueing
button
to
raise
the
tonearm,
and
then
press
the
stop
button
intermittently,
the
arm
will
move
outward
in
small
steps.
@ Start button:
When
you
press
the
start
button,
an
LED
(4)
lights
up
momentarily
and
the
tonearm
automatically
moves
to
the
record’s
lead-in
groove
and
the
record
starts
playing.
(Auto-start,
auto-lead-in.)
If you keep the button depressed, the LED lights up and the
tonearm
moves
inward
(4)
toward
the
center
of
the
record.
Press harder and the tonearm will move faster (44).
{f you press the cueing button to raise the tonearm, and then
press the start button intermittently, the arm will move
inward in smail steps.
© Cueing button:
Press the cueing button to raise or lower the tonearm. This
is useful for temporarily interrupting record play, or for
cueing the tonearm to a different selection on the record.
A muting circuit cuts out undesirable noise produced when
the stylus tip initially contacts the record grooves (y) or
is raised (¥).
© Rep (repeat) button:
When you press the rep button, an LED lights up and the
record is played repeatedly from beginning to end.
When you want to stop this cycle, merely press the rep
button again. Pressing the stop button will cause the tone-
arm to rise and return to the start position; it will also stop
repeat operation.
@® Power switch:
When you press this button (=), the stroboscope and tone-
arm indicator light up.
When you press it again, everything turns off.

Cabinet lock button:
Press the cabinet lock button to unlock the cabinet. Then
open the top gently. To close the cabinet, gently push it
down until it clicks shut.
Dust cover
Light guide slits:
Infrared light passing through these slits is used for opto-
electronic detection of record size (30, 25, 17 cm or 12”, 10”,
7’).
Center spindle
45 rpm adaptor:
This built-in adaptor is used for single-play 45 rpm records,
Press down lightly on the adaptor while turning counter-
clockwise and the adaptor will pop up ready for use. After
use, press down and turn clockwise.
Turntable platter
Lower cabinet:
Contains turntable drive mechanism.
Speed select knob:
Turntable speed is chosen automatically according to opto-
electronic detection of record size while the speed select
knob is in auto-position. There is, therefore, no need to
manually choose turntable speed or record size.
However, in those cases where speed does not correspond
to standard record size (a 30 cm (12") 45 rpm record, or
17 cm (7") 33-1/3 rpm record, for example), you must
manually select the correct speed by means of this knob.
Optical sensor:
This detects light coming through the guide slits in the
platter and thereby detects the size of the record being
played. It also detects whether there is a record on the
platter or not.
Disc size selector:
Set this selector to the size of the record to be played when
playing transparent records, records other than black or
nearly transparent black records as these surfaces do not
reflect the optical sensor beam.
