About MP3
MP3 (MPEG-1 Audio Layer III) is a standard format for audio compression technology. By
using MP3, a file can be compressed to one-tenth the size of the original.
This unit has limitations on MP3 file standards and recorded media and formats that can be
used. Be aware of the following points when recording MP3 files.
Playable MP3 file standards
• Supported standards
MPEG-1 Audio Layer III
• Supported sampling frequencies :
32, 44.1, 48 (kHz)
• Supported bit rate
32 to 128 (kbps)
• Supported channel modes
stereo, monaural, dual channel, joint stereo
* Supports VBR.
* Does not support free format.
* Bit rates vary for MPEG-1 and MPEG-2.
Use 128kbps or lower for the MP3 bit rate. If the bit rate exceeds 128kbps, there
may be sound cutting in and out during MP3 playback.
ID3 tags
MP3 files have an "ID3 Tag" that allows input of information so that data such as song title and
artist can be saved.
This unit supports ID3v.1.0 and ID3v.1.1 tags. Use only ASCII code to record tags, since only
ASCII code is supported by this equipment. Recording of characters not included in ASCII
code will result in display of garbled characters.
Media capable of playing MP3 includes CD-ROM, CD-R and CD-RW discs.
Compared to CD-ROM media commonly used for music discs, CD-R and CD-RW discs are
fragile in high temperature/high humidity environments and one section of the CD-R/CD-RW
may become incapable of playback. Fingerprints or scratches on the disc may prevent
playback or cause skipping during playback.
Sections of CD-R/CD-RW may deteriorate if left inside a vehicle for long periods of time.
It is also recommended that CD-R/CD-RW discs be kept in a light-blocking case because the
discs are vulnerable to ultra-violet light.

Format of discs
The format of discs to be used must be as following:
• Disc format
• File format
ISO9660 Level 1 or Level 2
ROMEO system, JOLIET system
MP3 files recorded in a format other than the one explained above may result in files that
cannot be played normally and in file names and folder names that do not display properly.
Limitations in addition to standards are as follows.
• Maximum directory layers
8 layers
• Maximum characters for folder names/file names :
30 (including "." and 3 letter file
• Allowable characters for folder names/file names :
A to Z, 0 to 9, _ (underscore)
• Number of files/folders possible on a single disc :
Each file that is not an MP3 file (files with extensions other than "MP3") is also counted as a
Configuration example for CD supporting MP3
A total of 512 files and folders can be
created within a single folder.
Each file that is not an MP3 file
(example: 004.TXT) is also counted as
a file.
• A total of 1023 files and folders can be recorded on a single disc.
File names
Only files with the MP3 file extension ".mp3" can be recognized as MP3 and played. Be sure
to save MP3 files with the ".mp3" file extension.
Use half-width English capital letters to write "MP" of the extension.
Multisessions are supported and CD-R/RW with recorded MP3 files can be played. When
written with "Track at once", however, finalize the disc with session close or write protect.
Playing MP3
When a disc having MP3 files recorded on it is inserted into the main unit, the system first
checks all the files on the disc. If the number of files and folders is large, the check will take
some time.
In order to speed up completion of the file check, it is recommended that you avoid recording
files that are not MP3 files and avoid establishing unnecessary folders.
While the system is checking the disc, the music that had been playing continues to play.
In addition, it is recommended that you record all data in a single session because a
multisession disc takes time for CD control information acquisition.
When MP3 is being played, navigation operation will become slower. This is not a
malfunction of the system.
MP3 playing time display
It is possible that playing time will not be correct, depending on the writing condition of the
MP3 file.
* It is possible that playing time will not be correct when VBR Fast Up/Down is operated.
Display order of MP3 file/folder names
Names of MP3 folders and files within the same level are displayed in the following order.
1. MP3 files displayed first, by ascending order of numbers, letters.
2. Folders displayed next, by ascending order of numbers, letters.
If the ".mp3" file extension is attached to a file other than an MP3 file, that file will
be mistakenly recognized by the main unit as an MP3 file and played, resulting in
loud noise output that can damage the speakers. Be sure to avoid attaching the
".mp3" file extension to files that are not MP3 files.

Making and playing MP3 files
MP3 files created by recording broadcasts, records, audio recordings, video recordings or
live performances cannot be used for purposes other than personal entertainment without
permission of the copyright holder as set forth in copyright law.
Downloading from Internet MP3 music sites
There are many kinds of sites that distribute MP3 files on the Internet, such as "pay per
download" online shopping sites, "try before you buy" listening sites and free download sites.
Follow the rules for each site (such as paying fees) and download according to site
Converting CD music to MP3 files
Prepare a computer with commercially available MP3 encoding software (conversion
software). (Some encoding programs available on the Internet do not require payment.)
Music data files in MP3 format can be made by inserting the music CD into the CD-ROM
drive of the computer and following the procedures of the MP3 encoding software to
compress the songs of the music CD. A 12cm music CD (having a maximum of 74 minutes
of recording/650MB of data) can be compressed to 65MB (about 1/10 of the original size).
Writing to CD-R/CD-RW
MP3 files can be recorded on CD-R/RW by using a CD-R/RW drive connected to a computer.
Record by setting the recording format of the recording software to ISO9660 level 1 or level 2
(not including extension format).
Select CD-ROM (mode 1) for the disc format. Discs recorded with CD-ROM xA (mode 2)
cannot be played on the main unit.
When playing back CD-R/RW
Insert a CD-R/RW disc having recorded MP3 files. The system will automatically determine
whether the disc is a music CD or a CD-R/RW with MP3 files and begin playing the disc. A
music CD recorded onto a CD-R/RW can also be played. However, depending on the type of
disc being used, a disc may not play.
• A fixed bit rate of 128kbps and sampling frequency of 44.1kHz is recommended
for obtaining stable audio quality at playback.
• Depending on the characteristics of a disc, CD-R and CD-RW may not be able
to read the disc.
• Because there are many types of MP3 encoding software available, including
commercial and freeware programs, audio quality may deteriorate, noise may
be generated when playing starts and some recordings may not play,
depending on the condition of the encoder and the file format.
• When files other than MP3 files are recorded on a disc, the system may take
some time to recognize the disc and it may not play the disc.
