@ ADJUSTMENTS
Speed adjustment (with pitch control knobs)
(See Fig. 2)
Strobe dots are set on the rim of the turntable platter
according to the power-time frequency and the number
of
revolutions
of
the
records.
Make
adjustment,
referr-
ing
to
strobe-dot
indication.
1. Place a record on the turntable mat.
2.
Set
the
speed
selector
to
the
speed
to
be
adjusted.
3. Adjust the speed while playing a record.
The
strobe-illuminator/pilot
lamp
will
be
lit
for
illuminating
the
strobe
dots.
4. While turning the pitch control knobs either to “+”
side or “—"’ side, adjust so that the strobe dots of the
turntable
platter
look
as
if
they
were
stationary.
The
state under which the strobe dots seem to be
stationary
represents
the
correct
number
of
revolu-
tions.
Strobe dots
The strobe dots for 60 Hz,
33'/3rpm seem tobe
Stationary.

“+"" direction
This
increases
the
speed
of
the
turntable
rotation,
and
the
strobe
dot
pattern
seems
to
flow
in
the
same
direc-
tion
as
the
rotational
direction
of
the
turntable
platter.
“—""
direction
This
decrease
the
speed
of
the
turntable
rotation,
result-
ing
in
a
state
opposite
to
that
in
the
+”
direction.
Note:
Strobe
dot
pattern
The
Strobe-illuminator/pilot
lamp
of
this
unit
employs
the
commercially
available
power
source.
The
frequency
of
such
power
source,
when
actually
measured,
has
a
fluctuation
of
about
2%.
As
such
a
fluctuation
of
the
power
source
affects
the
strobe
illuminator,
the
strobe
dot
pattern
also
seems
to
fluctuate
to
a
certain
extent.
But
the
unit
is
not
affected
by
these
fluctuations
of
the
power
source,
since
a
DC
motor
is
employed.
In
other
words,
rotation
of
the
platter
will
be
constant,
and
slight
shifts
in
the
movement
of
the
dots
simply
reflect
normal
drift
in
the
power-source
frequency.

Adjustment for automatic return position (See
Fig. 3)
(Remove the turntable mat.)
In cases where the tonearm tends to return before play-
ing has finished.
—Rotate clockwise.
In cases where the tonearm fails to return after the last
groove of the record.
—Rotate counterclockwise.

Adjustment of arm-lift height (See Figs. 4 and 5)
¢ The arm-lift height distance between the stylus tip
and record surface when cueing control is at ‘’ ¥ ‘’ has
been adjusted at the factory before shipping to ap-
proximately 5 to 10 mm.
e For using different cartridges available on the market
or when further adjustments are particularly neces-
sary, make adjustment as follows:
1. Put on the stylus protector to protect the stylus tip
from damage.
2. Set the speed selector to the “e” position to prevent
the turntable platter from rotation.
3. Turn the adjustment screw clockwise or counter:
clockwise, while pushing the arm lift down. (See Fig.
4.)
Clockwise rotation
— distance between the record and stylus tip is re-
duced,
Counterclockwise rotation
— distance between the record and stylus tip is in-
creased.
