■CD player protection feature
To protect the internal components, playback is automatically stopped when
a problem is detected while the CD player is being used.
■ If CDs are left inside the CD player or in the ejected position for
extended periods
CDs may be damaged and may not play properly.
■ Lens cleaners
Do not use lens cleaners. Doing so may damage the CD player.
■ 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
TMAudio) 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 and to the media/formats
recorded by them that can be used.

Media that can be used for MP3 and WMA playback are CD-Rs and CD-

Playback in some instances may not be possible, depending on the status
of the CD-R or CD-RW. 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

●File names
The only files that can be recognized as MP3/WMA and played are those
with the extension .mp3 or .wma.
● Multi-sessions
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 and 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 unnec-
essary folders.
Discs that contain a mixture of music data and MP3 or WMA format data
cannot 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 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be possible in some instances, depending 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 encod-
ing 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 possible at all.
• Microsoft, Windows, and Windows Media are the registered trademarks of Microsoft Corporation in the U.S. and other countries.
■ CD-R and CD-RW discs
● CD-R/CD-RW discs that have not been subject to the “finalizing process”
(a process that allows discs to be played on a conventional CD player)
cannot be played.
● It may not be possible to play CD-R/CD-RW discs recorded on a music
CD recorder or a personal computer because of disc characteristics,
scratches or dirt on the disc, or dirt, condensation, etc. on the lens of the
unit.
● It may not be possible to play discs recorded on a personal computer
depending on the application settings and the environment. Record with
the correct format. (For details, contact the appropriate application manu-
facturers of the applications.)

258 3-3. Using the audio system
PRIUS_U_(OM47614U)
●CD-R/CD-RW discs may be damaged by direct exposure to sunlight,
high temperatures or other storage conditions. The unit may be unable to
play damaged discs.
● If you insert a CD-RW disc into the MP3/WMA player, playback will begin
more slowly than with a conventional CD or CD-R disc.
● Recordings on CD-R/CD-RW cannot be played using the DDCD (Double
Density CD) system.
