EON (Enhanced Other Network) system (for traffic announcement function)
If the RDS station (with EON data) you are listening to is not broadcasting a traf-
fic information program and the audio system is in the TA (traffic announce-
ment) mode, the radio will be switched automatically to a station broadcasting a
traffic information program in the EON AF list when traffic information begins.
When the 12-volt battery is disconnected
All preset stations are erased.
Reception sensitivity
Maintaining perfect radio reception at all times is difficult due to the continu-
ally changing position of the antenna, differences in signal strength and sur-
rounding objects, such as trains, transmitters, etc.
When the “AST” button is used, automatic station selection may not be possi-
ble.
The radio antenna is mounted inside the rear window. To maintain clear radio
reception, do not attach metallic window tinting or other metallic objects to the
antenna wire mounted inside the rear window.
Digital Audio Broadcast (DAB) radio
The optional radio antenna and tuner are necessary for the use of Digital Audio
Broadcast (DAB) radio.

Lens cleaners
Do not use lens cleaners. Doing so may damage the CD player.
If discs are left inside the CD player or in the ejected position for extended peri-
ods of time
The discs may be damaged and may not play properly.
MP3 and WMA files
MP3 (MPEG Audio LAYER 3) is a standard audio compression format.
Files can be compressed to approximately 1/10 of their original size by using
MP3 compression.
WMA (Windows Media Audio) is a Microsoft audio compression format.
This format compresses audio data to a size smaller than that of the MP3 format.
There is a limit to the MP3 and WMA file standards that can be used and to the
media/formats on which the files are recorded.

CT200h_OM_OM76102E_(EE)
Compatible media
Media that can be used for MP3 and WMA playback are CD-Rs and CD-RWs.
Playback in some instances may not be possible if the CD-R or CD-RW is not
finalized. Playback may not be possible or the audio may jump if the disc is
scratched or marked with fingerprints.
Compatible disc formats
The following disc formats can be used:
• Disc formats: CD-ROM Mode 1 and Mode 2
CD-ROM XA Mode 2, Form 1 and Form 2
• File formats: ISO9660 Level 1, Level 2, (Romeo, Joliet)
MP3 and WMA files written in any format other than those listed above may
not play correctly, and their file names and folder names may not be dis-
played correctly.
Items related to standards and limitations are as follows:
• Maximum directory hierarchy: 8 levels (including the root)
• Maximum length of folder names/file names: 32 characters
• Maximum number of folders: 192 (including the root)
• Maximum number of files per disc: 255
File names
The only files that can be recognized as MP3/WMA and played are those with
the extension .mp3 or .wma.
Discs containing multi-session recordings
As the audio system is compatible with multi-sessions, it is possible to play
discs that contain MP3 and WMA files. However, only the first session can be
played.

ID3 and WMA tags
ID3 tags can be added to MP3 files, making it possible to record the track title,
artist name, etc.
The system is compatible with ID3 Ver. 1.0, 1.1, and Ver. 2.2, 2.3 ID3 tags.
(The number of characters is based on ID3 Ver. 1.0 and 1.1.)
WMA tags can be added to WMA files, making it possible to record the track
title and artist name in the same way as with ID3 tags.
MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc are
first checked. Once the file check is finished, the first MP3 or WMA file is
played. To make the file check finish more quickly, we recommend you do not
write in any files other than MP3 or WMA files or create any unnecessary fold-
ers.
Discs that contain a mixture of music data and MP3 or WMA format data can-
not be played.
Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and
WMA files, they will be mistakenly recognized and played as MP3 and WMA
files. This may result in large amounts of interference and damage to the
speakers.
Playback
• To play MP3 files with steady sound quality, we recommend a fixed bit rate
of at least 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances, depend-
ing on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3 and
WMA files on the market, and depending on the status of the encoding and
the file format, poor sound quality or noise at the start of playback may
result. In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may take
more time to recognize the disc and in some cases, playback may not be pos-
sible at all.
• Microsoft, Windows, and Windows Media are the registered trademarks of
Microsoft Corporation in the U.S.A. and other countries.
