Together with a center speaker mounted at the center of the dash, Dolby Pro Logic Surround Sound offers much clearer and more realistic sound.
Through a connection to a special decoder (optional on certain models), as well as a center speaker (option), the normal left-right stereo channels are divided into left-center-right. In addition, "surround" sound can be created from the car's rear speakers.
Most modern discs are recorded so that vocals are heard in the center foreground, while
the orchestra is heard across the entire
left-right range, as well as from behind.
Press the `MODE' button to engage the center speaker and the surround unit. The mode selected will be displayed.
"3 CH" = center speaker also engaged.
"Dolby Pro Logic" = Dolby Pro Logic engaged with surround effect from rear speakers *.
First press the button in slightly to pop it
out, then pull the button out completely and turn
it to adjust the volume of the center speaker.
First press the button in slightly to pop it
out, then pull the button out completely and turn
it to adjust the volume level from the rear speakers (Dolby Pro Logic only).
SC-901 - will not function in AM Radio mode.
Settings for individual markets are usually
adjusted in the factory or at the retailer. If you need to change this setting: switch off the
radio; hold down preset button 5 (A); switch on the radio (A) and press preset button 5
again until the relevant market (US, AUS or EU) appears.
To select the frequency correction:
· Switch off the radio.
· Hold down preset button 2 (B).
· Switch the radio on again.
· Press button 2 until the desired curve appears : S70-V70-S40-V40-Custom.
· Select "Custom EQ" by switching off the radio, holding down preset button 2 and switching the radio again. Select "Custom" (see point B). · Press Scan.
· Press preset button 1-5 within 5 seconds:
Preset button 1 = set bass (60 Hz)
Preset button 2 = set mid-range bass (200 Hz)
Preset button 3 = set lower mid-range (800 Hz)
Preset button 4 = set upper mid-range
(3 kHz)
Preset button 5 = set treble (12 kHz)
· Adjust the setting by turning the Tune knob clockwise (increase) or counterclockwise (decrease). The change can be seen in the display, as well as heard.
· Use preset button 6 to adjust the settings of the front or rear speaker.
F = Front
R = Rear
Please note that the equalizer curves can be adjusted separately for the front and rear speakers.
· When you are satisfied with the adjustments you have made, press Scan again to store the settings.
· Press Scan once again to exit the settings mode.
· To select "Custom EQ", press the
Volume knob.

Corporation.· Store cassettes in their cases.
· Do not touch the tape surface with your fingers.
· Tapes should not be exposed to direct sunlight or extreme temperatures.
· Keep tapes away from oil, grease and other contaminants.
· For optimal tape deck performance Volvo does not recommend the use of C-120 tapes.
· Take up slack using a pen or a pencil before inserting a cassette in the cassette slot.
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.
· Before using a new disc 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.
· Use high quality discs only.
· 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.
· Never use cleaning spray or antistatic liquid. Use only cleaners specifically made for CD's.
· Use discs of the correct size only (3.5" discs should never be used).
· Do not put tape or labels on the disc itself.
· Volvo does not recommend the use of plastic outer rings on the disc.
· 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.
· Never attempt to play a disc which is damaged in any way.
· When not in use, the discs should be
stored in their covers. Avoid storing discs in excessive heat, direct sunlight or
dusty locations.
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.
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.
The reason why FM but not AM is audible in 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.
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 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 disturbance as AM.
AM reception is sensitive to electrical disturbances such as power lines,
lightning, etc.
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 sender.
We hope that this information proves to be useful and 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.
NOTE: Always lower the antenna when using an automatic car wash or entering a garage.
The antenna should be cleaned at least every 15,000 miles (24,000 km) or more frequently if needed. Use WD40* for cleaning.
Spray the antenna with WD40 and wipe it clean and dry with a 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.
* Avoid spraying WD 40 on any painted surfaces as this could cause damage to the paint.
Certain models are equipped with the optional Diversity dual antenna system. Two
antennas are connected to the radio through two separate sockets, allowing for better
reception and reducing the effects of static or
multipath distortion of FM reception.
