Setting
of
the
Anti-Skating
Device
Before
setting
the
anti-skating
device,
check
that
the
arm
has
been
correctly
set
as
described
earlier.
Setting
of
the
correct
anti-skating
force
depends
on
two
factors,
namely
a)
the
stylus
pressure,
b)
the
tip
radius
of
the
stylus
of
the
cartridge
being
used.
Two
separate
anti-skating
weights
are
supplied
with
the
L
78,
namely
a
1
g
and
a
4
g
weight.
A
list
of
settings
for
all
stylus
pressures
and
tip
radii
is
shown
in
Table
2
on
the
last
page.
Example
To
set
the
anti-skating
force
for
a
cartridge
for
which
the
recommended
stylus
pressure
is
1.5
pond,
and
of
which
the
stylus
has
a
tip
radius
of
18
mu.
(.0007"),
Table
2
shows
that
for
a
stylus
pressure
of
1.5
pond
and
stylus
tip
radius
of
.0007"
the
1
g
weight
should
be
used
on
Notch
6.
Therefore
hang
the
1
g
weight
(28)
over
Notch
6
passing
the
thread
over
the
adjacent
hollow
in
the
cork-screw
(29)
so
that
it
hangs
freely.

to
revolve.
3.
Place
the
pick-up
arm

is
above
the
run-in
groove
of
the
record.
4.
Move
the
arm
lift
lever
(8)

5.
The
turntable
L
78
has
an
automatic
stop
com-
bined
with
an
automatic
lift
of
the
pick-up
at
the
end
of
the
record,
as
long
as
the
knob
at
the
rear
adjacent
to
the
pick-up
pedestal
is
set
to
‘automatic’.
6.
If
this
automatic
facility
is
not
required,
such
as
for

language
courses,
set
the
knob
to
‘MAN’
(manual).
At
the
end
of
the
record,
move
the

Should
you
wish
to

during
playing,
proceed
as
described
in

above.
Checking
and
Adjusting
the
Turntable
Speed
1.
Place
the
stroboscope
(round
aluminium
disc
with
three
rings
of
dark
and
light
stripes),
that
is
provided
with
each
unit,
on
the
turntable.
.
Start
the
motor
and
illuminate
the
stroboscope
with
a
light
from
a
lamp
connected
to
the
mains.
It
is
suggested
that
the
room
be
darkened
to
facilitate
the
setting.
If
the
speed
setting
of
the
speed
control
lever
is
correct,
then
all
the
dark
lines
on
the
ring
for
the
corresponding
speed
on
the
stroboscope
will
appear
to
stand
still.
If
how-
ever
they
move,
then
it
is
a
sign
that
the
speed
setting
has
altered.
The
speed
can
easily
be
cor-
rected
by
lifting
the
speed
contro!
lever
out
of
its
catch
and
moving
it
slightly
to
either
right
or
left.
When
the
speed
is
correct
the
stripes
on
the
stroboscope
will
appear
to
stand
still.
If
an
inten-
tional
deviation
from
the
pre-set
speed
is
requi-
red
(e.
g.
if
a
musical
instrument
is
being
played
and
the
pitch
of
the
record
is
to
be
adjusted
to
that
of
the
instrument),
then
the
speed
can
be
altered
in
the
same
way.
If
the
speed
is
to
be
re-
set,
i.
e.
a
re-adjustment
of
the
catch
for
the
cor-
responding
speed
is
required,
then
the
following
procedure
should
be
adopted:
a)
Loosen
slightly
(not
more
than
two
turns)
the
screw
at
the
side
of
the
corresponding
catch.
b)
Set
the
speed
change
lever
in
the
catch
and
adjust
the
speed
until
the
correct
speed
is
reached.
c)
Carefully
lift
the
speed
change
lever
out
of
the
catch
without
altering
the
position
of
the
catch,
and
re-tighten
the
screw.
