The
tonearm
is
correctly
balanced
when
it

when
it

Tracking
force
adjustment
In
order
to
provide
optimum
reproduction
of
the
sound
signals
cut
into
the
record
groove,
a
certain
pressure
—
called
"tracking
force”
—
must
be
applied
to
the
stylus.
If
you
purchased
your
turntable
with
a
factory-mounted
Dual
cartridge,
you
will
find
the
correct
tracking
force
in
the
data
sheet
supplied
with
the
unit.
After
adjusting
the
tonearm
balance
as
described
above,
set
the
tracking
force
by
adjusting
the
dial
ringof
the
counterweight
4
.
The
tracking
force
can
be
continuously
set
within
the
range
from
0
to
30
mN
(0
-
3
g),
whereby
the
digits
on
the
scale
represent
the
following.

Anti-skating
The
skating
force
acting
upon
any
tonearm
leads
to
onesided
wear
of
the
stylus
and
record
and
can
cause
distorted
repro-
duction.
For
stylus
types
generally
available
nowadays,
separate
setting
scales
are
available
in
accordance
with
the
printed
symbols:
O
Setting
for
spherical
styli.
O
Setting
for
biradial
(elliptical)
styli.
Adjustment
of
the
anti-skating
device
should
be
carried
out
to
match
the
setting
of
the
stylus
pressure:

this
may
be
done
by

Note:
To
play
records
of
non-standard
size,
such
as
25
cm
LP
(10”)
discs
or
direct-cut
records
(e.g.
30
cm
records
to
be
played
with
45
RPM),
your
turntable
must
be
operated
ma-
nually.
See
Part
2
“Manual
operation”.
Regardless
of
operating
mode
(automatic
or
manual),
the
tone-
arm
will
return
to
the
arm
rest
automatically
at
the
end
of
the
record.
Simultaneously
the
power
will
be
cut
off
and
the
platter
stops
rotating.
We
recommend
to
always
lock
the
tonearm
to
the
arm
rest
and
to
swing
down
the
stylus
guard
when
the
turntable
is
not
in

Pitch
control
Each
of
the
two
standard
speeds
(33
1/3
and
45
rpm)
can
be
varied
with
the
pitch
control.
Adjustment
is
made
with
pitch
control
knob
18.
The
pitch
control
maintains
the
nominal
speed
and
provides
for
individual
control
of
tempi
and
pitch
of
reproduction,
for
example,
when
the
pitch
of
recorded
music
is
to
match
a
live
musical
instrument,
or
when
a
record
passage
is
to
match
the
length
of
a
motion
picture
scene.
The
set
speed
can
be
checked
with
the
aid
of
the
illuminated
stroboscope
on
the
outside
edge
of
the
platter.
The
stroboscope
ring
for
the
set
speed
and
mains
frequency
appears
to
stand
still
when
the
platter
is
turning
at
precisely
the
nominal
speed
(Fig.
4).
