MP3 (MPEG 1 Audio Layer-3) is a standard technology and format for
compressing a sound sequence. The file is compressed to about 1/10 of its
original size. Sounds outside the range of human hearing are compressed
while the sounds we can hear are not compressed.

Notes on discs

You can play MP3 files recorded on CD-ROMs, CD-Rs (recordable CDs),
and CD-RWs (rewritable CDs). The disc must be in the ISO 9660*
level 2 format, or Joliet or Romeo in the expansion format. You can use a
disc recorded in Multi Session*

*1ISO 9660 Format

The most common international standard for the logical format of files
and folders on a CD-ROM.
There are several specification levels. In Level 1, file names must be in
the 8.3 format (no more than eight characters in the name, no more than
three characters in the extension “.MP3”) and in capital letters. Folder
names can be no longer than eight characters. There can be no more
than eight nested folder levels.
In level 2, file names can be up to 31 characters long (including the
delimiter, the dot “.”, and the extension “. MP3”). Each folder can have
up to 8 trees.
For Joliet or Romeo in the expansion format, make sure of the contents
of the writing software, etc.

*2Multi Session

This is a recording method that enables adding of data using the Track­At-Once method. Conventional CDs begin at a CD control area called
the Lead-in and end at an area called Lead-out. A Multi Session CD is a
CD having multiple sessions, with each segment from Lead-in to Lead­out regarded as a single session.
CD-Extra: A format that contains audio tracks (audio CD data) in

Session 1, and a data track in Session 2.

Mixed CD: A format that contains a data track and audio tracks (audio

FAQ- about MP3 Audio File

Q1 What is MP3?

MP3 (MPEG Audio Layer3) is a standard
for compressing audio parts of Moving
Pictures Experts Group (MPEG).
The special feature of MP3 is that the music
data is compressed to about 1/10 of its
original size while retaining the same
sound quality as a CD or an MD.
Compared with an audio disc (maximum
74 minutes running time), MP3 lets you
compress about 10 audio discs or 160 four­minute songs into a CD-R/RW of 650MB.

Note

Recorded music is limited to private use only. Use
of music beyond this limit requires the permission
of the copyright holders. Copyright law prohibits
copying, distributing, or delivering all or part of
the contents.

Q2 What kind of MP3 files can be

played back?

format other than ISO 9660 level 1 may
not be displayed correctly. When
creating MP3 data CDs, the format of ISO
9660 level 1 is recommended.

• When naming, be sure to add the file
extension “.MP3” to the MP3 file name.
The unit cannot recognize an MP3 file
without the extension “.MP3,” or a file
that is not MP3 format, even with the

Pour éviter toute blessure, ne pas introduire la main dans le
changeur de CD.

If the disc magazine does not lock properly

Take out the magazine, and after pressing the (EJECT) button,
re-insert it.

Si vous ne pouvez pas fermer le chargeur de disques

Sortez le chargeur et, après avoir appuyé sur la touche (EJECT),
réinsérez-le.

Note

When a disc magazine is inserted into the CD changer or the reset button of the connected car audio is pressed, the unit will
automatically be activated and read the information on the CDs. When the information on all the CDs in the disc magazine has been
read, the unit will automatically stop operation. The unit firstly reads all of the disc information in the disc magazine. Depending on
the recording method, it may take some time to stop the operation even if you set the ignition key to OFF during disc reading. This is
not a malfunction.

Remarque

Quand un chargeur de disques est inséré dans le changeur de CD ou si la touche de réinitialisation de l’autoradio raccordé est
enclenchée, l’appareil se met automatiquement en marche et reproduit les CD. Lorsque tous les CD du chargeur ont été reproduits,
l’appareil s’arrête automatiqement. L’appareil commence par lire toutes les informations relatives au disque dans le chargeur de
disque. Selon la méthode d’enregistrement, l’arrêt de l’opération peut demander quelques instants avant de s’arrêter si vous tournez
la clé de contact sur OFF au cours de la lecture du disque. Il ne s’agit pas d’un dysfonctionnement.

With the cut-away portion of the tray facing you, insert the right corner of the tray in
the slot, then push in the left corner until it clicks.

Note

Do not insert the tray upside down or in the wrong direction.

Avec la portion découpée du plateau vous faisant face, insérer le coin droit du plateau
dans la fente, puis enfoncer le coin gauche jusqu’au déclic.

Remarque

Ne pas insérer le plateau à l’envers ou dans le mauvais sens.
