Then
tune

ANTENNA
HEIGHT_
For best
FM
reception,
adjult
antenna
height
to
approximately
30
inches. The
30
inch antenna height
will
allo
provide good
AM
reception
in
most
areas.
SETTING PUSH-BUTTONS. Each push-
button
can be set
to
one station
only-either
an AM
or
an
FM
station. This provides a
total
of
five stations
that
can be selected
by
push-
button
operation. These five stations can be five
AM
stations, five
FM
stations
or
any combination
of
five
AM
and
FM
stations-for
exampl,
e,
four
AM
and
one
FM,
or
two
AM and three
FM
. Stations can be set up in any order; however,
for
con-
venience in remembering, stations should be set up in the order
of
their
frequencies_
Set push-buttons
as
follows:
l.
Turn radio on and allow
to
operate
for
a few minutes.
2.
Extend antenna height
to
30
inches.
3.
Turn BAND switch
to
either
AM
or
FM
, depending upon which broadcast band
the
desired station is on.
4.
Pull
out
push-buttons. (See Figure.)
5.
Accurately
tune
in a station
with
the
manual SElECTOR controI.
6.
lock
one push-button
to
that
station
by
pushing
button
in
firmly
.
7.
Repeat Steps 3
to
6
for
each
of
remaining
four
push-buUons.
NOTE: In metropolitan areas,
it
is recommended
that
the
push·buUons be set
up
in a shielded place where signals are weak, such
as
under a viaduct
or
in a
building
using steel in
its
structure.
FM-AM
RADIO
INTRODUCTION
TO
FM
There are
many
advantages
of
FM
radio-high
fidelity
reception relatively free
from
noise
with
a
fine
selection
of
programs,
many
of
which are
not
otherwise
available. Your VOLVO
AM·FM
radio
is designed
to
make
the
most
of
these advantages;
it
brings
you
the
enjoy·
ment
of
both superiaT radio
performance
and excellence
of
programs
.
FM
RECEPTION RANGE
The effective range
of
FM
radio
stations
is
not
as
great
as
AM
stations
.
This
is
mainly
due
to
the
fact
that
FM
radio signals
travel
through
the
air
in
straight
lines and are easily
blocked by obstacles such as hill ranges and
the
curvature
of
the
earth. In effect,
FM
radio
signals behave as
light
waves. Because
of
this
characteristic,
the
usual range
of
an
FM
station
may
be
only
25
miles. However, you will
find
there
to
be exceptions
to
this
range.

However,
with

of

the

inta
areas where
AM
reception is
almost
impossible-such
as
under

among
tall

As
you
drive
away
from
the
radio
station
and
inta
weaker signal areas, you will
notice
a
decrease in FM
performance
. The radio will also
start
to
pick·up
interference. The inter·
ference is due
to
the
fact
that
the
radio relies on a certain
minimum
level
of
signal
strength
to
provide noise·free reception. Therefore, when
listening
to
a weak signal,
it
is
normal
for
the
radio
to
pick
up
noise
from
surrounding
cars and
other
electrical devices.

In weak signal areas, you will also notice
that
the
radio program
may
fade
out
completely
or
fl
utter
in a sim
ilar
manner
to
a TV
picture
when
an
airplane
is
flying
overhead.
This
occurs because
the
weaker signals are easily blocked
from
the
radio
by
surrounding
objects. Fade·out and fl
utter
are
most
pronounced
when
driving
in areas having valleys
or hill ranges.

AFC
CIRCUIT
RECEPTION
IS

IN
THIS
AREA
AS

BLOCKED
BY
RANGE
OF
HILLS
The
AFC
(Automatic
Frequency
Control)
circuit
reduces
the
effect
of
FM
drift.
It
keeps
the
radio
tuned
to
the
station
which you have selected. However,
the
ability
of
the
AFC
to
hold
the
radio
tuned
to
a
station
is
dependent
upon
the
strength
of
the
FM
signal;
that
is,
the
AFC
will
hold
the
radio
tuned
to
a
stronger
station
much
better
than
it
will
to
a weak
station. Therefore, as you
drive
away
from
a
station
and
the
signal becomes weaker,
it
is
possible
for
the
AFC
circuit
to
automatically
tune
in a claser,
more
powerful
station
.
ANTENNA CONSIDERATIONS
The
regular
automotive
antenna
installed
with
your
radio will
provide
sufficient
reception
of
FM
radio
stations.
However,
due
to
a
characteristic
of
the
FM
signal, best reception
will be
obtained
by
adjusting
the
antenna
to
a
height
of
approximately
30
inches. You
will also
find
that
a
30
inch
antenna
height
will provide
sufficient
reception
of
AM
stations
in
most
areas.
