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

provides you with a better
understanding of the problems
related to car radio reception.

Reception conditions are not
always optimum and this is, of
course, beyond our control.
However, we have endeavored
to make the Volvo Audio
System of a quality that will
enable you to enjoy the best
possible reception no matter
what the reception conditions
may be. rag. Spray it again. Lower and
raise the antenna. Wipe it clean
and dry again. Lower and raise
the antenna 4-6 times. Make
sure it is dry and free from dirt
or lubricating oil.
damaged. When cleaning the
window be careful that the wires
are not scratched by rings, etc. If
they are damaged, radio
reception will be impaired.

WARNING!

Detergents and solvents
Do not use gasoline containing lead or benzene as a detergent or solvent\
. Both lead and benzene are
toxic and may be hazardous to your health.

Installation of optional equipment/use of mobile telephones
Incorrectly installed optional equipment, alarm systems or the use of mo\
bile telephones which are not
connected to a suitable antenna can cause faults in the car's electronic\
control systems. Your car is
equipped with an accessory connector located under the dashboard on the \
driver's side. Please consult
your Volvo retailer if you have any questions before connecting accessor\
y or optional equipment to
the vehicle's electrical systems.

Carbon monoxide
Carbon monoxide is a poisonous, colorless and odorless gas which is pres\
ent in all exhaust gases. If
you ever smell exhaust fumes from inside the vehicle, make sure the pass\
enger compartment is
ventilated and immediately return the vehicle to your retailer for corre\
ction.
Never sit in a parked or stopped car for any extended amount of time, nor hav\
e it unattended while
the engine is running.
Never operate the engine in confined, unventilated areas.

The following should be
checked regularly:

Coolant level should be
between the expansion tank
marks. Mixture: 50% anti-
freeze and 50% water. See
page 118.

Power steering - When
cold, the level must not be
above the COLD mark and
when hot it must not be
above the HOT mark. Top
up if the level drops to the
ADD mark with ATF fluid.
See page 116.

Engine oil - level should be
between the dipstick marks.
The distance between the
marks represents approx. 1
US qts. (1 liter). See page
108.

Brake fluid - check,
without removing the cap,
that the level is above the
MIN mark. Use brake fluid
DOT 4+. See page 116.

Washer fluid - reservoir
should be filled with water
and solvent (wintertime:
windshield washer anti-
freeze). See page 119.

Octane rating, see page 55.

Tire pressure, see label located on
the rear edge of the right front
door.
