Stop
At
the
end
of
a record, the tonearm
is
automatically
returned
to
the
tonearm rest
if
the
runout
groove
of
the record
cor-
responds
with
normal standards.
You
can also
switch
off the turntable by
setting
the
cue
con
trol
lever
in

and then setting
the
tonearm
back
onto the tonearm
rest.
Pitch control
Each
of
the
two
standard speeds
(33 1i3
and
45 rpm)
can be
varied
with
the pitch control. Adjustment is carried
out
using
the
pitch control knob 5
.
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
selected
turntable
speed
can
be checked
with
the aid
of
the stroboscope
on the
outer edge
of the turntable.

this
is
illuminated
with
a light operating on alternating current, then
