Welcome !
Thank you for purchasing the Sony Changer
Control Audio Master. This unit lets you enjoy
a variety of features as well as an optional
rotary commander.
In addition to the CD playback, tape playback
and radio operations, you can expand your
system by connecting an optional MD/CD
unit*.
*You can connect a CD changer, an MD changer, a
CD player and an MD player.
Precautions
• If your car was parked in direct sunlight
resulting in a considerable rise in
temperature inside the car, allow the unit to
cool off before operating it.
• If no power is being supplied to the unit,
check the connections first. If everything is in
order, check the fuse.
• If no sound comes from the speakers of
two-speaker systems, set the fader control to
the centre position.
•If your car is equipped with a power aerial, it
will extend automatically while the unit is
operating.
If you have any questions or problems
concerning your unit that are not covered in
this manual, please consult your nearest Sony
dealer.
Moisture Condensation
On a rainy day or in a very damp area,
moisture may condense on the lenses inside
the CD player. Should this occur, the unit will
not operate properly. In such a case, remove
the disc and wait for about an hour until the
moisture has evaporated.
To maintain high quality sound
If you have drink holders near your audio
equipment, be careful not to splash juice or
other soft drinks onto the unit and CD/
cassette. Sugary residues on the unit or CD/
cassette may contaminate the lenses or
playback heads inside the unit, reduce the
sound quality, or prevent sound reproduction
altogether.
Cassette cleaning kits cannot remove sugar
from the tape heads.

Notes on CDs
A dirty or defective disc may cause sound
dropouts while playing. To enjoy optimum
sound, handle the disc as follows.
Handle the disc by its edge. To keep the disc
clean, do not touch the surface.
Do not stick paper or tape on the disc.
Do not expose the discs to direct sunlight or
heat sources such as hot air-ducts, or leave
them in a car parked in direct sunlight where
there can be a considerable rise in temperature
inside the car.
Before playing, clean the discs with an optional
cleaning cloth. Wipe each disc from the centre
out.
Do not use solvents such as benzine, thinner,
commercially available cleaners, or antistatic
spray intended for analog discs.
Notes on discs
If you use the discs explained below, the sticky
residue can cause the CD to stop spinning and
may cause malfunction or ruin your discs.
Do not use second-hand or rental CDs that
have a sticky residue on the surface (for
example, from peeled-off stickers or from ink,
or glue leaking from under the stickers).
There are paste residue.
Ink is sticky.
Do not use rental CDs with old labels that are
beginning to peel off.
Stickers that are
beginning to peel away,
leaving a sticky residue.
Do not use your CDs with labels or stickers
attached.
Labels are attached.
Notes on CD-R discs
•You can play CD-Rs (recordable CDs) on this
unit. However depending on the conditions
of the recording equipment or the CD-R disc
itself, some CD-Rs cannot be played on this
unit.
•You cannot play a CD-R that is not finalized
(Finalization is necessary for a recorded CD-
R disc to be played on the audio CD player).
•You cannot play CD-RWs (rewritable CDs)
on this player.
When you play 8 cm CDs
Use the optional Sony compact disc single
adaptor (CSA-8) to protect the CD player from
damage.

Notes on Cassettes
Cassette care
• Do not touch the tape surface of a cassette, as
any dirt or dust will contaminate the heads.
• Keep cassettes away from equipment with
built-in magnets such as speakers and
amplifiers, as erasure or distortion on the
recorded tape could occur.
• Do not expose cassettes to direct sunlight,
extremely cold temperatures or moisture.
• Slack in the tape may cause the tape to be
caught in the machine. Before you insert the
tape, use a pencil or similar object to turn the
reel and take up any slack.
• Distorted cassettes and loose labels can cause
problems when inserting or ejecting tapes.
Remove or replace loose labels.
•The sound may become distorted while
playing the cassette. The cassette player head
should be cleaned after each 50 hours of use.
Cassettes longer than 90 minutes
The use of cassettes longer than 90 minutes is
not recommended except for long continuous
play. The tapes used for these cassettes are
very thin and tend to be stretched easily.
Frequent playing and stopping of these tapes
may cause them to be pulled into the cassette
deck mechanism.
