ADJUSTMENT
ADJUSTMENT OF TONEARM LEVER
Set the turntable unit upside down after putting the tone-
arm on the arm rest and securing it.
Then, loosen the set screw (w/hex hole) and position the
lever (M18) in such a way that the protrusion of the micro-
switch contacts the foremost end of the lever.
ADJUSTMENT OF MICRO-SWITCH
Set the turntable unit back in its normal position (the
turntable platter at the top). Loosen the round hend screw
(Y7) (see illustration) with a screwdriver and adjust the
microswitch
position
so
that
the
micro-switch
will
be
turned on when the tonearm has moved a little toward the
turntable center.
The micro-switch should be correctly positioned at a place
where it provides a rotational start for the turntable when
the tonearm head centers an area 35 through 38cm away
from the center.
ADJUSTMENT OF AUTO-RETURN
There
is
a
shaft
which
is
accessible
with
an
long
shaft
screwdriver
through
the
hole
below
the
tonearm.
(See
illustration
at
right.)
When
the
stylus
has
reached
a
point
approximately
55mm
from
the
turntable
center
turn
the
shaft
clockwise
or
counter-clockwise
and
select
a
position
where
it
actuates
the
auto-return.
ADJUSTMENT OF HEADSHELL
The headshell attached to the tonearm should not be
inclined either to the right or to the left. If necessary,
loosen the two screws on the bottom of the tubular arm
and adjust the headshell. Be sure that the stylus is normal to
the record surface.

ADJUSTMENT
ADJUSTMENT OF TONEARM LIFTER
Set
the
cuing
lever
to
UP
and
the
distance
between
the
stylus
and
the
record
to
about
9mm
_
by
adjusting
the
arm
lifter
screw.
ADJUSTMENT
OF
LIFT-UP
LEVER
SPRING
Switch
off
power
when
the
auto-return
has
worked
and
adjust
spring
tension
to
provide
a
clearance
of
11mm
between
the
stylus
and
the
record.
ADJUSTMENT OF TURNTABLE SPEED
Set
the
fine
speed
control
dials
to
their
center
positions
(each
has
three
protrusions,
of
which
only
one
can
be
set
to
the
center).
Make
adjustment
by
inserting
a
screwdriver
into
the
holes.
When
properly
adjusted,
the
zebra
strobo-
scope
marks
on
the
turntable
platter
seem
to
be
stationary
at
the
selected
speed.
