Hold
the

between
the
thumb and
the
index
finger
of the
right
hand and
slant
it
inside
the
pick-up
head
so
that the guide bar of the
pick-up cart-
ridge sets into the wide
cut-out.
Speaker volume
The
desired
volume is
set
by means
of
the
volume control. This
control is
tone
com-
pensated
and boosts bass and treble
at
low
volume settings
in
accordance
with
the charactql.istics of the
human
ear. lndi-
vidual adjustment
of
reproduction
can
be
set
by
the
bass and
treble
controls.
Tone controls
For
optimum adjustment
of
reproduction
to
personal taste,
the unit
is
equipped with
extremely
effective bass and treble
con-
trols.
For best results,
first
listen
with
the
controls in the center
positions.
This
will
provide
linear frequency response.
Then,
depending
on the volume level, raise
or
lower bass and
treble
as
desired.

4.
Turning the knob counterclockwise

clockwise
lowers the
tonearm.
The tonearm is accu-
rately balanced when the tonearm
returns
to
this position
by
itself
when
it
is
lighily
tapped.
Precise balancing of the tonearm is
espe-
cially
important
with
cartridges
specified
for
low tracking
forces.
The
tonearm needs
to
be
balanced only
once
unless
a
cartridge
of
a
different
weight is
substituted.
Applying tracking force
With the
tonearm balanced
at
"0",
apply
tracking
force by
turning
the
calibrated
dial
to
the desired
number.
The
Dual
pro-
vides
for
applying tracking
force
in
a con-
tinuing
range
from
0 to
S,5
grams.
For
the correct
stylus
force, follow
the
instruc-
tions provided with the cartridge.
