 CD-R/CD-RW discs that contain audio tracks
and conform to the CD-DA* 1 standard.
 CD-R/CD-RW discs that contain MP3 files and
are finalized* 2 correctly.
*1 CD-DA is the abbreviation for Compact Disc
Digital Audio. It is a recording standard used for
audio CDs.
*2 Finalizing is the process to make the CD-R/
CD-RW discs playable on the consumer disc
player products, and the finalizing can be
enabled or disabled as optional settings during
disc creation in most recording software.
Discs that this unit CANNOT play
 CD-R/CD-RW discs other than those recorded
in audio CD format or formats conforming to
ISO 9660 Level 1/Level 2 or Joliet
 CD-R/CD-RW discs of poor recording quality,

finalized incorrectly
 CD-R/CD-RW discs that contain files created in
audio formats other than MP3
Notes on discs
 Before playing, clean the CD with
a cleaning cloth. Wipe the CD
from the center out. If there are
scratches, dirt or fingerprints on
the CD, a tracking error may occur.
 Do not use solvents such as
benzine, thinner, commercially
available cleaners or anti-static
spray intended for vinyl LPs.
 Do not expose the CD to direct sunlight or heat
sources such as hot air ducts, or leave it in a
car parked in direct sunlight as there can be a
considerable rise in temperature inside the car.
 Do not stick paper or a sticker on the CD, or
scratch the surface of the CD.
 After playing, store the CD in its case.
Note on DualDiscs
 A DualDisc is a two sided disc product which
mates DVD recorded material on one side with
digital audio material on the other side.
However, since the audio material side does
not conform to the Compact Disc (CD)
standard, playback on this product is not
guaranteed.
Music discs encoded with copyright
protection technologies
 This product is designed to playback discs that
conform to the Compact Disc (CD) standard.
Recently, various music discs encoded with
copyright protection technologies are
marketed by some record companies. Please
be aware that among those discs, there are
some that do not conform to the CD standard
and may not be playable by this product.
Notes on cassettes
 Remove the overwrite protection tab from side
A or B to prevent accidental recording. If you
want to reuse the tape for recording, cover the
broken tab using adhesive tape.

 The use of a cassette tape with more than
90 minutes of play time is not recommended
except for long, continuous recording or
playback.
On safety
 As the laser beam used in the CD player
section is harmful to eyes, do not attempt to
disassemble the casing. Refer servicing to
qualified personnel only.
 Should any solid object or liquid fall into the
unit, unplug the unit, and have it checked by
qualified personnel before operating it any
further.
 Discs with non-standard shapes (e.g., heart,
square, star) cannot be played on this unit.
Attempting to do so may damage the unit. Do
not use such discs.
On power sources
 For AC operation, use the supplied AC power
cord; do not use any other cord.
 Unplug the unit from the wall outlet if it is not
to be used for an extended period of time.
 When not using the batteries, remove them to
avoid damage that can be caused by battery
leakage or corrosion.
On placement
 Do not leave the unit in a location near heat
sources, in a place subject to direct sunlight,
excessive dust or mechanical shock, or in a car
subject to the direct rays of the sun.
 Do not place the unit on an inclined or
unstable surface.
 Do not place anything within 10 mm of the rear
of the cabinet. The ventilation openings must
be unobstructed for the unit to operate
properly and prolong the life of its
components.
 Since a strong magnet is used for the speakers,
keep personal credit cards using magnetic
coding or spring-wound watches away from
the unit to prevent possible damage from the
magnet.
On operation
 If the unit is brought directly from a cold to a
warm location, or is placed in a very damp
room, moisture may condense on the lens
inside the CD player section. Should this occur,
the unit will not operate properly. In this case,
remove the CD and wait about an hour for the
moisture to evaporate.
On handling the unit
 Do not leave the CD compartment open to
avoid dust and debris contamination.
On cleaning the cabinet
 Clean the cabinet, panel and controls using a
soft cloth slightly moistened with a mild
detergent solution. Do not use any type of
abrasive pad, scouring powder, or solvent, such
as alcohol or benzine.
If you have any questions or problems
concerning your unit, consult your nearest Sony
dealer.
