ADJUSTMENT
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.
NOTE: Do not take out these screws.
ADJUSTMENT OF TONE ARM SET-DOWN.
When
the
start/stop
(START/STOP)
button
is
pressed
to
start
for
the
automatic
operation,
the
stylus
descends
automatically
and
sets
down
on
the
lead-in
groove
of
the
record.
Though
this
adjustment
has
been
made
properly
by
the
factory,
the
stylus
may
set
down
too
far
inside
or
outside
of
the
lead-in
groove.
Therefore
when
mounting
an
alternative
cartridge,
if
this
|
\|
occurs, you can correct as follows:
NOTE:
Remove
the
rubber
cap
covering
the
adjustment
hole
hytl
before
making
the
adjustment.
Replace
it
after
adjusting.
a.
Be
sure
the
overhang
and
anti-skating
force
adjustments
have
been
made
correctly.
Also,
check
if
the
cartridge
shell
has
been
mounted
horizontally
to
the
tone
arm.
b. Place a 12’’ (30 cm) record on the turntable.
c. Set the speed/disc size select (SPEED) button to the “33”
position. |
d. In the automatic operation, turn the adjusting screw
clockwise or counter-clockwise as shown in Figure so that Ww
the stylus tip will correctly set down on the lead-in groove
of the record.
NOTES:
*
If
the
stylus
tip
sets
down
too
far
inside
of
the
lead-in
grooves,
turn
the
adjustment
screw
clockwise.
*
Jf
it
sets
down
too
far
outside
of
the
lead-in
grooves,
turn
it
accordingly
counter-clockwise.
Turning
the
adjustment
screw
too
far
will
cause
the
arm
return
not
to
function
correctly.

ADJUSTMENT
ADJUSTMENT OF STYLUS HEIGHT
Setting
the
record
disk
in
place,
raise
the
tonearm
lift
lever.
Bring
the
tonearm
to
above
the
disk,
and
insert
a
screw-
driver
into
the
‘‘stylus
height
adjust’’
hole
(see
drawing
for
ADJUSTMENT
OF
AUTO-RETURN)
and
turn
it
right
or
left
until
the
distance
between
the
disk
and
stylus
becomes
7to8mm.
RECORD DISK
ADJUSTMENT OF TURNTABLE SPEED
Setting the pitch control in the middle position, place the
speed select switch in the 45 rpm position. Insert a screw-
driver from the bottom of deck panel and turn SVR2 until
the stroboscope pattern appears dead.
Similarly, change to 33 rpm position, and adjust by turning
SVR1.
