! If you insert a CD-RW disc into this pro-

duct, it will take more time to play back

than when you insert a conventional CD or

CD-R disc.

! Read the precautions with CD-R/CD-RW

discs before using them.

MP3 files

! When naming an MP3 file, add the corre-

sponding filename extension (.mp3).

! This navigation system plays back files with

the filename extension (.mp3) as MP3 files.

To prevent noise and malfunctions, do not

use this extension for files other than MP3

files.

! MP3 is short for MPEG Audio Layer 3 and

refers to an audio compression technology

standard.

! This product allows playback of MP3 files

on CD-ROM, CD-R and CD-RW discs. Re-

corded discs can be played back if they are

compatible with level 1 and level 2 of

ISO9660 and with the Romeo and Joliet file

system.

! It is possible to play back multi-session

compatible recorded discs.

! MP3 files are not compatible with packet

write data transfer.

! The maximum number of characters for

the file and folder name is 32 characters,

including extension (.mp3). However the

navigation system uses proportional font.

Therefore, the number of the characters

that you can display varies according to the

width of each character.

! When playing discs with both MP3 files

and audio data (CD-DA), such as CD-

EXTRA and MIXED-MODE CDs, both types

can be played only by switching the mode

between MP3 and CD-DA.

! The folder selection sequence for playback

and other operations is the writing se-

quence used by the writing software. For

this reason, the expected sequence at the

time of playback may not coincide with the

actual playback sequence. However, there

also are some writing software that permit

the setting of the playback order.

! Some audio CDs contain tracks that merge

into one another without a pause. When

these discs are converted to MP3 files and

burned to a CD-R/CD-RW/CD-ROM, the

files will be played back on this player with

a short pause between each one, regard-

less of the length of the pause between

tracks on the original audio CD.

! Files are compatible with the ID3 Tag Ver.

1.0 and Ver. 1.1 formats for displaying

album (disc title), track (track title) and ar-

tist (track artist).

! The emphasis function is valid only when

MP3 files of 32 kHz, 44.1 kHz and 48 kHz fre-

quencies are played back. (16 kHz,

22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, 48 kHz

sampling frequencies can be played back.)

! There is no m3u playlist compatibility.

! There is no compatibility with the MP3i

(MP3 interactive) or MP3 PRO formats.

! The sound quality of MP3 files generally im-

proves with an increased bit rate. This pro-

duct can play recordings with bit rates

from 8 kbps to 320 kbps, but in order to be

able to enjoy sound of a certain quality, we

recommend only using discs recorded with

a bit rate of at least 128 kbps.

! Playing MP3 file on the DVD-R (-RW) is not

supported.

About folders and MP3 files

An outline of a CD-ROM with MP3 files on it is

shown below. Subfolders are shown as folders

in the folder currently selected.

p The following figure is an example of the

tier structure in the CD. The numbers in the

figure indicate the order in which folder

numbers are assigned and the order to be

played back.

bers are assigned.
