Warning if your car’s ignition has no

ACC position

After turning the ignition off, be sure to press

and hold (OFF) on the unit until the display

disappears.

Otherwise, the display does not turn off and

this causes battery drain.

The BBE MP process

improves digitally

compressed sound, such as

MP3, by restoring and enhancing the higher

harmonics lost through compression. BBE MP

works by generating even-order harmonics from

the source material, effectively recovering

warmth, detail and nuance.

Additional Information

Precautions

• If your car has been parked in direct sunlight,

allow the unit to cool off before operating it.

• Power aerial will extend automatically while the

unit is operating.

Moisture condensation

On a rainy day or in a very damp area, moisture

condensation may occur inside the lenses and

display of the unit. 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 sound quality

Be careful not to splash juice or other soft drinks

onto the unit or discs.

Notes on discs

• To keep a disc clean, do not touch its surface.

Handle the disc by its edge.

• Keep your discs in their cases or disc magazines

when not in use.

• Do not subject discs to heat/high temperature.

Avoid leaving them in a parked car or on a

dashboard/rear tray.

• Do not attach labels, or use discs with sticky ink/

residue. Such discs may stop spinning when used,

causing a malfunction, or may ruin the disc.

• Do not use any discs with labels or stickers

attached.

The following malfunctions may result from using

such discs:

– Inability to eject a disc (due to a label or sticker

peeling off and jamming the eject mechanism).

– Inability to read audio data correctly (e.g.,

playback skipping, or no playback) due to heat

shrinking of a sticker or label causing a disc to

warp.

• 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.

• You cannot play 8 cm CDs.

• Before playing, clean the discs

with a commercially available

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 analogue discs.

Notes on CD-R/CD-RW discs

• Some CD-Rs/CD-RWs (depending on the

equipment used for its recording or the condition

of the disc) may not play on this unit.

• You cannot play a CD-R/a CD-RW that is not

finalized.

Music discs encoded with copyright

protection technologies

This product is designed to play back 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.

About MP3 files

MP3, which stands for MPEG-1 Audio Layer-3, is a

music file compression format standard. It

compresses audio CD data to approximately 1/10 of

its original size.

• The unit is compatible with the ISO 9660 level 1/

level 2 format, Joliet/Romeo in the expansion

format, ID3 tag version 1.0, 1.1, 2.2, 2.3 and 2.4,

and Multi Session.

• The maximum number of:

– folders (groups): 150 (including root and empty

folders).

– MP3 files (tracks) and folders contained in a

disc: 300 (if a folder/file names contain many

characters, this number may become less than

300).

– displayable characters for a folder/file name is

32 (Joliet), or 32/64 (Romeo); ID3 tag is 15/30

characters (1.0, 1.1, 2.2 and 2.3), or 63/126

characters (2.4).

Playback order of MP3 files

Notes

• Be sure to finalize the disc before using on the unit.

• When naming an MP3 file, be sure to add the file

expansion “.mp3” to the file name.

• If you play a high-bit-rate MP3, such as 320 kbps,

sound may be intermittent.

• During playback of a VBR (variable bit rate) MP3 file

or fast-forward/reverse, elapsed playing time may

not display accurately.

• When the disc is recorded in Multi Session, only the

first track of the first session format is recognized

and played (any other format is skipped). The

priority of the format is CD-DA, ATRAC CD and

MP3.

– When the first track is a CD-DA, only CD-DA of the

first session is played.

– When the first track is not a CD-DA, an ATRAC CD

or MP3 session is played. If the disc has no data in

any of these formats, “NO Music” is displayed.

About ATRAC CD

ATRAC3plus format

ATRAC3, which stands for Adaptive Transform

Acoustic Coding3, is audio compression

technology. It compresses audio CD data to

approximately 1/10 of its original size.

ATRAC3plus, which is an extended format of

ATRAC3, compresses the audio CD data to

approximately 1/20 of its original size. The unit

accepts both ATRAC3 and ATRAC3plus format.

ATRAC CD

ATRAC CD is recorded audio CD data which is

compressed to ATRAC3 or ATRAC3plus format

using authorized software, such as SonicStage 2.0 or

later, or SonicStage Simple Burner.

• The maximum number of:

– folders (groups): 255

– files (tracks): 999

• The characters for a folder/file name and text

information written by SonicStage is displayed.

For details on ATRAC CD, see the SonicStage or

SonicStage Simple Burner manual.

Note

Be sure to create the ATRAC CD using authorized

software, such as SonicStage 2.0 or later, or

SonicStage Simple Burner 1.0 or 1.1, which are

supplied with Sony Network products.

If you have any questions or problems concerning

your unit that are not covered in this manual, consult

your nearest Sony dealer.

Maintenance

Replacing the lithium battery of the

card remote commander

Under normal conditions, the battery will last

approximately 1 year. (The service life may be

shorter, depending on the conditions of use.)

When the battery becomes weak, the range of the

card remote commander becomes shorter. Replace

the battery with a new CR2025 lithium battery. Use

of any other battery may present a risk of fire or

explosion.

Notes on the lithium battery

• Keep the lithium battery out of the reach of children.

Should the battery be swallowed, immediately

consult a doctor.

• Wipe the battery with a dry cloth to assure a good

contact.

• Be sure to observe the correct polarity when

installing the battery.

• Do not hold the battery with metallic tweezers,

otherwise a short-circuit may occur.

Fuse replacement

When replacing the fuse, be

sure to use one matching the

amperage rating stated on the

original fuse. If the fuse blows,

check the power connection and

replace the fuse. If the fuse

blows again after replacement,

there may be an internal

malfunction. In such a case,

consult your nearest Sony

dealer.
