SYSTEM
@ Depress the POWER
switch to turn on the unit.
@ Make sure the PROGRAM
SENSOR
button is released.
O Select the FM or AM
band with the FUNCTION
selector.
© Set the MODE
selector to STEREO.
O Tune
in the
desired

with
the

knob.
See
"SIGNAL

eWhen
receiving
an
FM
stereo
signal,
the
STEREO
lamp
will
light up automatically.
O Adjust the volume
and tone
quality with
the controls of the
amplifier.
Notes
eWhen
FM
stereo
signals are noisy,
set the
MODE
selector to
MONO
for the best possible signal under noise conditions.
eTo tune
in a very weak
station, lower the volume
and set the
MUTING
switch to OFF.
FOR A SIMPLE TUNING
IN OF A NON-PRESET STATION
To tune in the desired FM or AM
station, turn the TUNING
knob
so that the frequency of that station appears at the Digital Display.
e When
an FM station is tuned
in, the LOCKED
lamp
lights up.
While
the LOCKED
lamp
is lit, the quartz-lock system assures a
stable tuning condition.
MAINTENANCE
Clean the cabinet,
panel and knobs periodically with a soft cloth.
If fingerprints, food
and
beverage
stains,
etc. are difficult to re-
move,
use a cloth moistened with a mild detergent solution.
Do
not
use
any
type
of scouring
powder,
abrasive
pad or solvent,
since these will damage the cabinet.
FM ANTENNAS
Good
FM reception depends not only on the tuner sensitivity but
on the quality of the received signals.
This is determined
by the
signal strength, the presence of multipath signal and the geogra-
phic location of the
desired
FM
stations.
To get the best from
your tuner,
use
an
antenna
suited
to your
location.
Until
you
install
a suitable
antenna,
the
supplied
ribbon
antenna
may be
useful.
In a strong
signal
area,
the familiar
"rabbit-ears"
antenna
is
simple
to install and is well suited for FM
reception, since it can
be adjusted easily for best signal pickup.
If there are many high
structures
nearby,
and
evidence
of strong multipath
reception is
present, use a highly-directional rotatable outdoor antenna.
If you
wish
to receive
not only the local stations that an indoor
antenna
pulls in, but to reach out into areas where there may be
programs
more to your taste, use a high-gain
directional outdoor
FM antenna
properly installed with a rotator.
Ribbon dipole and rabbit-ears
antennas pick up signals from
both front and rear equally well.
Dipole antenna with reflector
has increased sensitivity to front
signals and reduced sensitivity
to rear signals.
Multi-element type has nar-
rower pickup pattern with high
frontal sensitivity and superior
rejection of rear and multipath
signals.
MULTIPATH
RECEPTION
The most important factor affecting FM signal quality is multipath
reception.
Multipath
is caused by signal reflections from
hills or
structures
that
reach
the
receiving
antenna
perceptibly
later in
time.
Particularly
with
FM
stereo,
multipath
can
cause
severe
distortion
and
complete
loss of channel separation.
The effects
of a multipath condition appear as high-frequency noise and dis-
tortion,
particularly
noticeable
in music
systems
with
extended
response.
The effects of multipath reception can be avoided to a
great
extent by using a coaxial or shielded twin lead lead-in, and
a good directional antenna that is correctly oriented.

FM ANTENNA
ORIENTATION
While
listening
to the
desired
FM
station,
adjust
the
antenna
direction
and
height
so that the SIGNAL indicator illuminates as
fully as possible, and so that the distortion is eliminated.
ein
some
cases,
obtaining
good
reception
from
two
or
more
stations
may
require that the
antenna
be pointed
in different
directions.
An
effective
solution
to this problem is the use of a
remotely-controlled rotatable antenna.
elf an
outdoor
antenna
cannot
be erected,
use
a good indoor
antenna
("rabbit-ears"
are
satisfactory).
Adjust
the
antenna
direction for minimum
distortion.
ein
locations
where
ignition noise is severe, the antenna should
be located as far away from the highway as possible.
