The AM and FM stereo radio with cassette player that is described on
these pages is a sophisticated electronic sound system, incorporating
numerous useful features - not all of them evident at a glance. To
maximize your listening pleasure, take a few minutes to carefully
review this guide. In it you'll find descriptions of the various features
and complete operating instructions.

BASIC CONTROLS

POWER
The stereo system will operate with the
car's ignition switch in either the "on" or
"off" position. To operate the radio, simply
touch the "on" side of the on-off switch
located at the lower left corner of the radio
faceplate.

A tape cassette can be played without
using the on-off switch by simply inserting
the tape into the cassette port. As soon as
the cassette is drawn into position, it will
begin to play.

VOLUME
Sound level is controlled by means of the
volume bar located on the left side of the
radio faceplate. Press upward to increase
volume, downward to decrease volume.

TONE
Two tone buttons, identified by musical
notes, are located directly above the
volume bar. The left button controls bass,
the right controls treble. A bar graph at the
extreme left of the radio display indicates
relative bass and treble settings.

To bring both bass and treble tones to their
midrange settings, press both buttons

simultaneously. To bring either bass or
treble tone to maximum level, press and
hold the respective button. In
approximately three seconds, the graph
will indicate maximum level. If the button
is released and pressed again, the tone level
will reach minimum level in approximately
five seconds. In order to reverse
adjustment direction, the maximum level
must be reached first. The system is
equipped with a memory function that will
"remember" adjustment levels for AM and
FM radio and cassette.

BALANCE
Left to right stereo balance is adjusted by
means of the same buttons used to control
bass and treble levels. Before adjusting
balance, the function control button, which
is on the right side of the radio display and
marked with a star (*), must be pressed.
Then, to shift sound balance to the left
speakers, press the bass control. To shift
sound balance to the right speakers, press
the treble control. Balance can be set to the
mid position by pressing both buttons
simultaneously. A visual indication of the
stereo balance setting is provided on the

radio display when the balance feature is
activated.

FADER
A fader control is provided on models
equipped with both front and rear speakers.
Located on the lower console near the gear
selector, this thumbwheel-operated control
can be adjusted to suit your preference.

Dialing the thumbwheel forward will
increase the output of the front speakers
while reducing that of the rear. Conversely,
dialing the thumbwheel backward will
increase the output of the rear speakers,
while reducing that of the front speakers.
Positioning the thumbwheel in its center
detent will equalize the sound levels.

ANTENNA
The automatic antenna is controlled by a
three-position rocker switch, located above
the radio. Under normal conditions the
switch should be set to its maximum
position, allowing the antenna to extend to
its full height for optimum reception.

TUNING

The electronic radio is capable of receiving
monaural and stereo broadcasts on AM and
FM wavebands. AM stereo broadcasts can
be received from stations that use the
Motorola C-Quam® System. A
"STEREO" indicator will appear on the
radio display whenever a stereo signal is
received.

To select the waveband you wish to hear,
simply press any one of the numbered
station select buttons located along the top
of the radio faceplate-1 through 6 for FM,
7 through 0 for AM. To tune to a specific
station, you may use any of the following
methods:

SEEK AND SCAN TUNING
The "SEEK" bar, located on the right side
of the radio faceplate, can be used to tune
in broadcast frequencies within AM or FM
wavebands. When the bar is pressed up,
the radio will automatically seek stations in
ascending frequencies; when pressed
down, it will do so in descending
frequencies.

The "SCAN" bar, located directly to the
right of the SEEK bar, allows sampling of

radio stations within a waveband for
approximately five seconds each.
Pressing the bar up will cause stations to be
scanned in ascending frequencies; pressing
it down will result in a scan of descending
frequencies. If no action is taken during the
five-second period, the radio will tune to
the next station. Pressing either the SEEK
or SCAN bar a second time will cause the
radio to stay tuned to the station being
sampled.

SENSITIVITY CONTROL
To account for differing signal strengths
when tuning with the seek or scan
functions, the radio is equipped with a
tuning sensitivity control. This feature
enables you to choose one of three
sensitivity levels by pressing the sensitivity
control button, located on the far right side
of the radio faceplate. The level you select
will be indicated by a single-, double- or
triple-ringed symbol appearing on the right
side of the radio display. In the low level,
the radio will seek and scan only the
strongest signals. In higher sensitivity
levels it will seek and scan less powerful
signals as well. The sensitivity level is
automatically increased one step each time

the entire waveband has been sampled
without finding a station.

DIRECT FREQUENCY TUNING
To tune directly to a specific frequency,
switch to your desired waveband-AM or
FM-as described, then press the function
control button, which is identified by a star
and located just to the right of the radio
display. The display will go blank. Next,
press the numbered buttons corresponding
to the digits of your desired station. For
example, to select the frequency 98.5, you
would first press the function control
button to clear the display. Then you would
press button numbers 9,8,5, in consecutive
order. The display would then register

98.5, and the station at that frequency
would begin playing.

The driver, of course, should not use the
direct frequency method when the vehicle
is in motion.

FINE ADJUSTMENT
The radio can also be fine tuned in
increments up or down through either
waveband. This is done using the two
buttons marked by arrows and located on
the lower right of the faceplate.

TUNING CASSETTE OPERATION

PUSHBUTTON

MEMORY TUNING
The most common and convenient method
of tuning is to store your favorite stations
in the radio's memory. Six FM stations and
four AM stations may be tuned this way by
using the numbered station select buttons
located along the top of the radio faceplate.

First using either the seek, scan or direct
frequency tuning methods, tune in the
station you wish to store. Next, push and
hold the numbered station select button
you wish to use for storing the station. The
radio will then display the station currently
stored at that number. Continue holding the
button until this station is deleted from
memory and the frequency of your newly
selected station appears on the display. The
station frequency will be stored in
memory.

To play a cassette, insert it into the cassette
port, tape side first, with the "1" or A"
designation facing up. The cassette will be
drawn automatically into the deck. At the
conclusion of the first track played, the
autoreverse mechanism will automatically
begin playing the other track of the tape.

All cassette functions are located directly
above the cassette port and appear from
left to right in the following order:

TAPE SWITCH ("CR")
This feature allows you to select the proper
equalization setting for playing chromium
dioxide (CrO2) or "metal" cassette tapes.
An LED located on the face of this button
will illuminate when this option has been
elected.

EJECT
To remove a cassette, push the eject
button. The tape will automatically
disengage and can then be retrieved from
the cassette port. Ejecting a cassette
switches the system to radio operation.

FORWARD MUSIC SEARCH/

FAST FORWARD
A cassette tape can be automatically
advanced to the next selection by pressing
the forward button once. An LED light on
the face of the forward button illuminates
to indicate that music search has been
activated.

To fast forward the tape to the end of the
track, press the forward button twice. The
LED will blink to indicate that the fast
forward function has been activated.

REVERSE MUSIC

SEARCH/REWIND
A cassette tape selection can be repeated
by pressing the reverse button once. The
LED light will illuminate to indicate that
music search has been activated. Push the
reverse button twice to rewind the tape.
Once engaged, it will lock into position
until the tape is fully rewound or until
another tape function is activated. The
LED will blink to indicate that the rewind
function has been activated.

TRACK SELECTION
Once a cassette has been engaged, this button can be used
to switch to the cassette's other track without having to

remove and flip the cassette.
