For stylus types
usual
or standardized nowadays, separate set-
ting 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
synchronously
to
setting
of
the stylus
pressure:
turn
the anti-
skating device
to
the digit
of
the scale
concerned,
which
cor-
responds
to
the
adjusted
stylus
pressure. For example,
in
the
case
of
15
mN (1
.5
p) stylus
pressure
also
place
the anti-skating
rotary
button in position
"1.5".
When playing
records moistened
with
a
cleaning agent,
the
skating
force
is
reduced
by
approximately
30 %.
ln this
case
we recommend
that
you
set
a
correspondingly lower
value.
Cue
Control
Your
unit
ls equipped
with
a
shock-f ree
cue
control
silicone-
damped
in both directions.
Thus
the tonearm can be lowered
to
any
desired
point
on the
record more gently
than is possible
by hand. The
cue-control
lever
(6)
has
two positions:
V
tonearm
raised
t
tonearm
on record
The cue
control
holds
the tonearm above
the
record, and
it
can
therefore be moved
to
any position
over
the record
with
complete safety.
A
light touch on
the
cue-control lever
(6) to
the
t
position
lowers
the tonearm
gently.
The
cue-control
re-
turns
to
the
!
position automatically at the end
of
the record.
With the cuelng
control in
!
position, the height
of
the
stylus
above
the record can
be
varied
by approximately 6 mm by
tur-
ning the adjusting screw
(1
).
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 (12).
Adjustment
range
at
33
1/3 rpm approx.
1
semitone
(6
%).
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
muslcal instrument,
or
when a record
passage
is
to
match the
length
of
a
motion
picture
scene.
Thö set speed
can be checked
with the aid
of the illuminated
stroboscope on
the outside edge
of the
platter
(Fig.3).
Despite
the rotation
of the
platter, the stroboscope markings
for
the
desired speed seem
to
stand
still
when
the
actual speed
of
the
platter
is
the same
as
the set speed.
Cartridge and stylus
please
refer
to the enclosed data sheet
supplied separately
with
your
unit.
Replacing
the cartridge
You mJy
release
the
complete cartridge
from the tonearm by
preising

to
the
rear
if
you havdpreviously
removed the safety screw
"S" (Fig'

Fig. 4/S).
Stylus
The stylus is
subjected
to
natural
wear and tear during normal
playing. Therefore, we recommend
you occasionally check the
stylusänd, in the
case
of
diamond
styli, this should
be
carried
out after
approximately
300 playing
hours
Your
specialist

remember
that,
for
physical
reasons,
the stylus holder

to
impacts, shocks
or
uncontrolled movement.
