6y a screw
and
can
be reached
by removing
the turntable
platter.

Removing
the turntable
platter
The
platter
is
secured
by
a
C-ring
seated
in
a notch
on
the
turntable
shaft.
Use a
screwdriver
to
remove
the
C-ring, then
lift
off the
platter.
Fig 22
r
lmportant: When
handling the
platter
avoid
touching
the inner surf
aces with
your
fingers
as
skin oils can cause
slippage
(and
resulting
pitch
deviation)
between the
idler wheel
and
the driving
rim of
the
platter.
Adjusting
tonearm
set-down
position
With
automatic
start,
the
stylus descends
automatically
into the
outer
groove
of the
record.
lt is
possible,
due to
peculiarities
in the
mounting
of a
cartridge,
that
the
stylus
may
land
too far
in
or too
fat
out
on the
record.
Fig.23
ln
that case,
set the
record size
selector
for
a 12"
record
(30
cm). Through
the
hole
next
to
the tonearm
rest,
you
will
see
an
adjustment
screw
@.
lf the
stylus lands
too
far into
the record,
turn the
screw
very
slightly
to the left;
if it lands
too
close
to the
edge,
turn
it slightly
to
the
right.
