Needless
to
say,
we
are
delighted
that
you
have
chosen
the
Dual

Now,
like
most

you
are
probably
eager
to

play
your
first

This
won’t
take
long,
but
it
is
important
that
you
read
the
installation
instructions
carefully
(on
the
inside
of
this
flap).
We
also
suggest
you
familiarize
yourself
with
the
1009F’s
many
operating
features
as
described
on
the
following
pages.
Each
of
them
is
a
typical
example
of
Dual’s
advanced
technology.
Pleasant

These
ingeniously
designed
mounting
screws
make
it
possible
to
install
and
remove
your
Dual
from
either
base
or
mounting
board
entirely
from
the
top.
There’s
no
need
to
fumble
underneath
or
to
take
anything
apart.
1.
Position
the
chassis
over
the
base
so
that
the
three
cupped
spring-mounted
footings
will
fit
into
their
cut-outs.
(The
notch
on
the
base
for
the
rear
top/mount
spring
screw
will
then
be
at
the
upper
left.)
Tilt
both
mounting
screws
to
let
them
slip
past
the
notches
as
you
lower
the
chassis.
(Fig.
5A)
2.
Turn
each
screw
clockwise
until
it
is
firmly
seated
into
the
top
of
the
chassis.
(Fig.
5B)
That’s
all
there
is
to
it.
To
remove
the
Dual,
simply
re-
verse
the
above
procedure.
To
Transport
the
Dual
Without
Demounting
1.
Loosen
both
top/mount
spring
screws,
depress
the
chassis
against
the
base,
then
continue
to
turn
each
screw
counter-clockwise
until
it
stops.
The
chassis
will
then
be
locked
firmly
against
the
base.
(Fig.
5C)
2.
To
avoid
possible
damage
to
the
platter
bearings
in
transit,
insert
the
plastic
wedges
(supplied
in
the
accessory
bag)
between
the
platter
and
chassis.
Position
the
wedges
at
equal
distances
for
maxi-
mum
support.
Or
you
can
remove.the
platter
from
the
chassis
(See
below).
With
the
chassis
now
on
its
base,
slowly
and
gently
lower
the
platter
onto
the
shaft.
The
oiled
felt
plug
in
the
center
hole
will
lubricate
the
shaft
as
it
is
forced
out,
and
it
may
then
be
discarded.
The
platter
can
be
secured
to
the
chassis
if
de-
sired,
by
the
spring-clip.
Use
the
special
accessory
cone
(supplied
in
hardware
bag)
to
press
the
spring-clip
down.
As
shown
in
fig.
25,
a
coin
makes
this
easy.
(The
same
cone
is
used
to
re-
move
the
spring-clip
as
shown
in
fig.
26.)
Finally,
insert
the
decorative
round
disc
under
each
of
the
three
lips
on
the
mat.
Mounting
the
Cartridge*
Note:
Any
cartridge
weighing
between
1
and
8
grams
and
meeting
standard
U.S.
mounting
specifications
can
be
used
with
the
Dual
1009F.
For
cartridges
weighing
up
to
13
grams,
order
special
counterbalance
shaft
12L-U118.
1.
Release
the
cartridge
holder
from
the
tonearm
head
by
pressing
the
tonearm
lift
a
short
turn
to
the
rear.
Be
ready
to
catch
the
holder,
as
it
will
drop
right
into
your
hand
(Fig.
10).
2.
The
special
gauge
supplied
with
your
Dual,
when
snapped
onto
the
holder
as
shown
in
fig.
9,
will
indicate
the
correct
stylus
depth
for
the
cartridge
when
mounted.
(Be
sure
the
ridges
on
the
inside
of
the
gauge
walls
fit
into
the
cor-
responding
tracks
on
the
side
of
the
cartridge
holder.)
When
the
cartridge
is
mounted
at
the
correct
depth,
the
tip
of
the
stylus
will
protrude
slightly
into
the
notch
of
the
gauge.
(Use
the
necessary
spacers
and
screws
provided
in
the
accessory
bag.)
3.
The
specially
tapered
wedge,
also
supplied,
is
for
use
when
you
intend
to
play
single
records
either
exclusively
or
primarily.
(Fig.
8)
This
wedge
provides
the
optimum
15°
vertical
tracking
angle
when
one
record
is
on
the
platter.
(However,
even
without
the
wedge,
the
vertical
tracking
angle
will
still
be
well
within
standard
industry
tolerances
for
single
record
play.)
4,
Remove
the
gauge
when
actually
mounting
the
cartridge,
then
snap
it
on
again
—
carefully
—
to
check
stylus
overhang.
When
viewed
from
the
top
(Fig.
9.
),
the
stylus
should
be
centered
within
the
notch
of
the
gauge.
5.
Finally,
tighten
screws,
making
sure
cartridge
is
positioned
straight.
Note
dotted
line
in
fig.9.
6.
Connect
each
lead
on
the
cartridge
holder
to
its
corresponding
pin
on
the
cartridge.
Each
lead
is
color-
coded
as
shown
in
fig.
10.
7.
Attach
the
cartridge
holder
by
placing
it
against
the
tonearm
head
as
shown
in
Fig.
11,
lift
it
up
and
lock
it
by
pressing
the

screw
the
shaft
of
the

2.
Lock
the
tonearm
on
its
post,
push
the
operat-
ing
slide
switch
to
START,
then
rotate
the
platter
by
hand
two
or
three
times
to
be
sure
the
switch
is
in
“neutral”
(Fig.

3.
Unlock
the
tonearm,
lift
it
off
the
rest
post,
and
rotate
the
counterbalance
until
the
tonearm
is
per-
fectly

To

As
a
further
confirma-
tion
of
perfect
tonearm
balance,
let
the
tone-
arm
float
freely,
then
tap
the
chassis
from
the
top.
The
tonearm
should
remain
hori-
zontal,
even
while
the
chassis
vibrates.
Perfect
tonearm
balance
is,
of
course,
especially
im-
portant
with
extremely
lightweight
tracking.

it
in
the

The
instructions
accompanying
your
cartridge
will
give
you
the
range
of
minimum
and

its
manufacturer
suggests.
As
the
tonearm
of
the
Dual
1009F
can
track

as
low
as

the
only
limitations
on
tracking
are
those
imposed
by
the

is
why
you
can
use
any
cartridge
you
prefer,

those

Adjustment
for
Lead-In
Groove
The
Dual’s
tonearm
has
been
carefully
set
at
the
factory
to
set
down
accurately
in
the
lead-in
groove
during
automatic
start.
However,
the
dimensions
of
some
cartridges
may
cause
the
stylus
to
set
down
either
too
far
in
or
too
far
out.
In
such
cases,
the
necessary
adjustment
can
be
made
quite
simply
as
follows:
1.
Move
record-size
selector
switch
to
7”
position.
This
will
expose
the
adjustment
screw
through
the
opening
in
the
chassis
near
the
tonearm
post.
2.
If
the
stylus
had
touched
down
outside
the
lead-
in
grooves,
turn
the
screw
clockwise
(very
slightly).
If
the
stylus
had
touched
down
on
the
recorded
grooves,
turn
the
screw
counter-clockwise.
(Although
it
is
most
convenient
to
use
a
7”
record,
any
size
record
can
be
used
to
make
and
check
the
adjustment,
as
once
the
tonearm
has
been
cor-
rectly
set
for
one
size
record,
it
will
be
correct
for
all.
Just
be
sure
to
set
the
size
selector
switch
back
for
the
record
size
you're
using
if
you
don’t
have
a7”
record.)
Servicing
if
your
Dual
1009F
ever
requires
servicing,
either
take
it
to
your
Dual
audio
dealer,
or
ask
him
for
the
address
of
the
nearest
Authorized
Dual
Service
Station.
Be
sure
that
authentic
Dual
parts
are
used
whenever
replacement
is
neces-
sary.
Always
ship
the
Dual
in
its
original
packag-
ing,
or
if
it
has
been
discarded,
write
for
special
shipping
instructions.
