A- CD slot

With the audio system on, insert
a disc into the slot with the label
side up. When the CD is
inserted, the radio is disengaged
and the CD will start to play
automatically.
The CD can be inserted or
ejected even when the unit is
switched off.

When the CD has been inserted
into the player, the "DISC IN"
light will always be ON even if
the radio, tape deck or CD
changer are in use. B- CD mode selector

Press "CD" to actuate the CD
mode. The track last listened to
will continue to play. If the CD-
player is empty, "NO CD" will
be displayed.
C- CD eject

If the button is pressed the CD
will stop and the disc will be
ejected. The radio will be
automatically engaged. The
radio, tape or CD changer will
engage automatically (depending
on which mode was activated
before the CD was played).

NOTE: If the CD eject button is
pressed and the disc is not
removed within 12 seconds, the
disc will be drawn into the CD

Cassettes
l Store cassettes in their cases.
l Do not touch the tape surface
with your fingers.
l Tapes should not be exposed to
direct sunlight or extreme
temperatures.
l Keep tapes away from oil,
grease and other contaminants.
l For optimal tape deck
performance Volvo does not
recommend the use of C-120
tapes.
l Take up slack using a pen or a
pencil before inserting a cassette
in the cassette slot.

Cassette cleaning

We recommend the use of the
Volvo Cleaning Cassette available
as a genuine Volvo accessory.
Regular use improves sound
quality, cleans vital parts and
prevents tape tangle. Compact disc care

l Before using a new disk for the
first time, remove any burrs in the
center/outer edge by running the
stem of a pen or similar object
around the hole/edge of the disc.
l Use high quality discs only.
l Keep the discs clean. Wipe
them with a soft, clean, lint-free
cloth, working from the center
outwards. If necessary, dampen
the cloth with a neutral soap
solution. Dry thoroughly before
using.
l Never use cleaning spray or
antistatic liquid. Use only cleaners
specifically made for CD's.
l Use discs of the correct size
only (3.5" discs should never be
used).
l Do not put tape or labels on the
disc itself.
l Volvo does not recommend the
use of plastic outer rings on the
disc.
l Condensation may occur on
discs/optical components of the
changer in cold winter weather.
The disc can be dried with a clean,
lint-free cloth. Optical
components in the CD changer
may, however, take up to one hour
to dry off.
l Never attempt to play a disc
which is damaged in any way.
l When not in use, the discs
should be stored in their covers.
Avoid storing discs in excessive
heat, direct sunlight or dusty

Sending signals

The FM waves do not follow
the earth's surface nor do they
bounce off the atmosphere. For
this reason their range is
limited. The AM waves follow
the earth's surface and reflect
against the atmosphere, giving
them a wide range.
Weak reception (fading)

Because of the limited range of
the FM senders and the fact that
these waves are very reflective,
this problem usually occurs
with FM reception. If the sender
is blocked by buildings or
mountains, static can result.

Static

The reason why FM but not AM
is audible is covered parking
areas, under bridges, etc, is that
FM signals reflect against solid
objects such as buildings.
Because these waves are very
reflective, static can result. This
static is the result of the reflected
signal and the direct signal
reaching your antenna at slightly
different times causing a
cancellation of all signals. This
problem occurs largely in built-
up areas. Your car is equipped
with a dual antenna system
which helps alleviate this
problem.

Cross modulation

If you listen to a weak station in
the vicinity of a stronger one,
both stations may be received
simultaneously. If the car is
moved a short distance, the
weaker signal may be heard
more clearly.
FM - reasons for distortion

FM is affected by the electrical
systems of nearby vehicles,
especially those without
suppression. The distortion
increases if the station is weak
or poorly set.
The FM reception is not as
sensitive to electrical
disturbances as AM.
AM - reasons for distortion

AM reception is sensitive to
electrical disturbances such as
power lines, lighting, etc.
Audio systems, general information (cont.) pg. 164
FM stereo reception

Stereo reception places very
high demands on the signal
quality which means the type of
distortions previously
mentioned become even more
obvious. The signal strength
needs to be stronger for good
stereo reception and this limits
the effective range of the
slender.
We hope that this information
proves to be useful and
Radio antenna (sedans)

NOTE: Always lower the
antenna when using an
automatic car wash or entering
a garage.

The antenna should be cleaned
at least every 10,000 miles
(16,000 km) or more frequently
if needed. Use WD40 for
cleaning.
Spray the antenna with WD40
and wipe it clean and dry with a Radio antenna (wagons)

The radio antennas (2) are built
into both side windows of the
cargo area. These antennas also
have factory installed antenna
boosters.
NOTE: The antennas will not
function without these boosters.

Place objects in the cargo area so
that the antenna wires on the
inside of the window will not be
