STORING
STATION
FREQUENCIES
IN
THE
TUNING
PRESETS
(1)
Decide
which
station
you want
to
assign
to
each
of
the
12
presets.
(You
don’t
have
to
use
them
all.)
You
may
arrange
the stations
in
any
order
that
you find
easy
to
remember
or
convenient
to
use.
For
example
the
arrangement
may
be
alphabetical
(1
=
WABC,
2
=
WCBS,
3
=
WNYC
...),
numerical
(1
=
BBC1,
2
=
BBC2,
...),
or
in
order
of
increasing
frequency
(1
=
89.7,
2
=
90.9,
3
=
92.3,
etc).
(2)
Select
the
FM
or
AM
band.
(3)
Tune
to
the
first station
on
your
list,
by
pressing
the
up/down
tuning
buttons.
If
you
are not
certain
of
the
frequency,
check
the station/frequency
directory
in
a
local
newspaper
or
broadcasting
guide.
Press
STORE
to
store
the
displayed
frequency
in
the
tuner’s
memory.
The
tuner
will
display
E01.
Press
STORE
to
register
the
stored
frequency
as
Pre-set
01.
(4)
Tune
to
the second
station
on
your list.
Press
STORE
to
store
that
frequency.
The
tuner
will
display
E01,
the last
preset
selected.
Press
to
advance
the
preset
number.
When
it
displays
E02,
press
STORE
to
complete
the
second
pro-set.
(5) Tune
to
the
third
station
on
your
list,
press
STORE
to
store
the frequency,
press
.
to
select
Pre
set
03, and
press
STORE
again
to
complete
the
third
entry.
Continue
with
this process
until
you have
stored
as
many
stations
as
you wish.
12
presets
are
provided
for
FM stations
and another
12
presets
for
the
AM
medium-wave
band.
After
you
finish
programming
the
pro-sets,
you
may wish
to
post
your
list
of
stations
and
associated
pro-set
numbers
nearby
for
reference.
Incidentally,
if
you make
a
mistake
or
change
your
mind,
it
is
not necessary
to
re-program
the
pre-sets
in
sequence.
You
can
re-program
any
pro-set
as
follows:
Tune
to
the desired
frequency,
press
STORE,
press
or
.4
to
select
the
preset
number
that
you
want
to
re-program,
and press
STORE
again.
The
pre-sets
preserve their
frequency
assignments
forever,
even
if
the
AC power
cord
is
unplugged.
Thus
you can
re-arrange
your stereo
system,
or
move
the
equipment
from
room
to
room,
without
losing
the
pre-set
frequencies.
TO CHANGE
THE AM TUNING
STEP
When
tuning
on the
AM
medium-wave
band,
the
frequency
changes by
increments
of
10
kHz
in
North
America
and 9

in
Europe.
The following
proce
dure toggles
the
tuning
circuit
between

ANTENNAS
FOR
BETTER
RECEPTION
A
ribbon-wire
“dipole”
antenna
may
provide
ade
quate
reception
of
strong
FM
signals.
But
such
an
antenna
is
not
very
efficient
at
rejecting
“muitipath”
and other
forms
of
FM
interference.
And
it
cannot
easily
be
rotated
to
optimize
its
pickup
pattern
for
best
reception
of
stations
in
different
directions.
In
most
cases
reception
can
be
improved
upon
by
using
an
outdoor
antenna.
The
best
choice
is
a
direc
tional
FM-only
antenna,
mounted
as high
above
ground
as
is
practical,
and
separated
by at
least
two
meters
(7
feet)
vertically
or
horizontally
from
any
other
antenna.
We
would
suggest
you contact
your
local
aerial
installation
company
to
advise
you
and
install
your
FM
aerial.
If
you
install
an outdoor
antenna
yourself,
observe
these
important
CAUTIONS:
(1) Do
not
mount
the
antenna
close
to
electric
power
lines.
Plan
the
installation
so
that
the
antenna
mast
cannot
fall
into
contact
with
power
lines,
either
while
you are
installing
it or
later.
(2) include
a
lightning
arrestor
in
the
installation,
to
protect
both
yourself
and
the
tuner
circuit
from
poten
tial
danger
during
electrical
storms.
USING
A
LONG-WIRE
ANTENNA
FOR
BETTER
AM
(MEDIUM-WAVE)
RECEPTION
To
improve
reception
of
distant
AM
stations,
attach
a
long-wire
outdoor
antenna
to
the
AM terminal.
A
“long-wire”
antenna
is
a
straight
wire
whose
length
may
be
anything
from
a
few
feet
up
to
about
100
feet
(30 meters),
mounted
parallel
to
the earth
and
as
high
as
Is
convenient.
If
your
are
living
close
to
an
AM
transmitter,
increasing
the
length
of
the
antenna
may
actually
decrease
the
quality
of
reception.
The
effectiveness
of
a
wire
antenna
may
be
improved
by connecting
a
second
wire
from
the
Ground
(G)
terminal
to
a
true
earth-ground,
i.e.
a
cop
per-plated
rod driven
several
feet
into
the
earth.
A
substitute
electrical
ground,
such
as
a
cold
water
pipe,
may
also
prove
effective.
