OWNER'S MANUAL
General Information
This AM/ FM stereo radio has been specifi ca lly designed for your Volvo. Like you r
Volvo, it is a dependable, high-qua lity unit. To enjoy great sound from it, please
read the operating instructions ca refully.

Mono·s tereo switch
Due to the different installation between VOLVO 1 64 and 240 series, the
appearance of the front panel varies. Pi c ture shown are for the VOLVO 240 series.

Operating Instructions
1. SWITCH AND VOLUME
CONTROL
The outer left-hand knob is a com-
bined
switch and volume controI.
2. MANUAL TUNI NG
Select the desiredwave band (FM
or AM) by pushing in one of the AM
or FM buttons. Tune in by rotati ng
the outer right -hand knob until the
desired station is obtained. Make sure
that you tune in exactly as otherwise
you will get poor tone quaiity and
interference.
3. TONE CONTROL
The tone (bass and treble) is con-
trolled by the inner left-hand knob.
4. PUSH-BUTTON TUNING
You engage the AM-band by depress-
ing one
of the AM-buttons and the
FM-band by depressing one
of the
FM-buttons . A fter the push buttons
have been set up, you get the desired
pre-set station
automatically by de-
pressing
the relevant button firmly.
5. SETTING PUSH BUTTONS
a. After selecting the wave band, un-
lock the first button by pulling it
out .
b.
Carefully tune in the station de-
sired with the manual tuning knob.
Tune in exactly.
c. Lock the station by firmly depress-
ing
the button.
d. Follow the above procedure on the
remaining
four buttons.

6. BALANCE CONTROL
The inner right-hand knob is the
balance controI. Turn it left or right
to shift the center of the sound as
desired.

7. MONO-STEREO SWITCH
The outer left-hand knob functions
also as a mono-stereo switch. Push to
enjoy stereo broadcasting auto-
matically.
Stereo indicator lamp turns on when
listening to stereo stations. When
stereo reception becom
es unco mfort-
able (i.e. the indi ca tor lamp start
blinking), pull the knob mona po-
sition.

be obtained from your Volvo dealer.
2. REAR SPEAKER
Optional rear speaker kit with fader
controi
is available from your Volvo
dealer under part number 283699-7.

SOME FACTS ABOUT RADIO
PERFORMANCE IN AUTOMOBILES
The inf ormation below will give you some understanding of the differences in
radio reception between home equ
ipm ent and car radios in a moving ve hicl e.
Performance of Signal Transmission
FM-RECEPTION -Shorter distance,
does not follow curvature of earth
and
is not reflected by upper atmo-
sphere.
AM-RECEPT ION -Long distance,
follows curvature
of earth and is
reflected by upper atmosphere.

FADING -Fading i.s not usually a problem with AM because of its long distance
reception capability. FM, on
the other hand, is limited to line-of-sight reception
(25
to 40 miles) under ave rage conditions of terrain and transmitted power.
The
area of good FM stereo reception may be even slightly less than that of re-
gula r FM because of stronger signal requirements. Reception behind hills may be
noisy (hissing, popping, etc.) -sometimes called fl utter or picket fencing.
METROPOLITAN RECEPTION - Transmitted FM signals are easily reflected by
solid objects such as buildings. This is why FM can be received underbridges and
between
tall buildings, whereas AM reception under the same conditions would
ei ther be reduced or non-existent.
MlJLTIPATH RECEPTION -The fact th at FM can be received quitewell between
tall buildings can, unfortunately, cause a detrimental side effect, namely multipath
reception. It is caused by a direct signal and a reflected one arriving at the vehicle's
antenna causing dis
tortion, partiai or complete loss of the station.
This
is mostly encountered in downtown areas.

AM Interference
INTERFERENCE AND IGNITION NOISE -AM-reception is susceptible to certain
types
of electrical interf erence. These include power lin es, thunderstorms, and
oth
er situations where electrical charges in the air cause disturbances resulting in
buzzing and stati
c. AM, how ever, does not usually suffer from ignition interference
of nearby vehicles because suppression equipme nt install ed on the vehicle prevents
ignition noise in the radio.
FM Interference
IGNITION NOISE INTERF ERENCE -FM does not usually suffer from the
e le ctr i ca l disturbances that can affect an AM receiver. FM, however, is siightly
sensitive
to ignition noise generated by engine of adjacent vehicles, espec ially
those not containing radio suppression equipment. Thi s ignition noise is more
prevalent when listeni
ng to a weaker station while driving in heavy traffic . The
noise
wi ll al so occur if the radio is tuned off-stat ion slightly ; to improve reception,
make sure the radio is tuned for minimum noise.

OTHER FM INTERFERENCE -Occasionally, when li ste ning to a station while
driving in the vic init y of another stati on, especially a strong one, the possibility
of receiving both sta tion s simultaneously can exist. The phenomenon is ca lled
adjacent channel interf erence or cross modulation.
FM Stereo Reception
FM stereo reception is much more complex than regular FM, which apparently
can increase t he frequency of the above-mentioned phenomena. Besides thiS,due
to st ronger signal requirements, the distance reception capab ility is more limit ed .
We hope the above information will co ntribut e to your understanding of the
challenges assoc iated with AM, FM and, especia lly FM-ster eo radio transmission.
You ha ve see n that the cond iti ons for undisturbed operation of your radio are
