However, maximum number of folder is
255.
Also, maximum number of the folder
level is 8.
The compression bit rate of MP3 files
that can be played with the unit is from
32 kbps to 320 kbps. However, for file
capacity and sound quality, 128 kbps
and above is recommended. When a file
compressed at 128 kbps or less is
played, sound quality may be inconsis-
tent Compatible sampling rates are as
follows:
MPEG 1 48k 44.1k 32k
MPEG2 24k 22.05k 16k
MPEG2.5 12k 8k
When both music CD data (CD-DA) and
MP3/WMA/AAC file data exist on one
disc, only the music data (CD-DA) is
played. Do not write a file other than
MP3/WMA/AAC or needless folder in the
disc.
The unit is compatible with files com-
pressed with VBR (Variable Bit Rate),
however, the playback time may not be
displayed correctly during fast-forward/
rewind.
The unit may not play MP3/WMA/AAC
files in the order of recording.

As the number of folders recorded on the
disc increases, the time to read the disc
information also increases.
Limitations of displayed
information
The unit only displays the folder and file
Only one-byte alphanumeric characters
and symbols can be displayed. If 2-byte
characters can be displayed, they will
display as 1 character. If 2-byte charac-
ter display is not possible, a “*” will be
displayed.
When playing MP3/WMA/AAC file, the
playback time may not be displayed
properly.
CAUTION
• The playback order may differ
depending on the writing software.
• Make sure to finalize the disc
before using on the unit.
• When naming an MP3/WMA/AAC
file, make sure to attach the exten-
sion “.mp3/.wma/.m4a” to the file
name.
• Do not attach the extension “.mp3/
.wma/.m4a” to files other than MP3/
WMA/AAC files. If a disc with such
a file is played, it will be mistakenly
recognized and it may cause
excessive noise to be emitted,
damaging the speaker.
• The unit may not be able to play
certain discs depending on disc
conditions, recording software or
the recorder used for writing the
data. In such cases, refer to the
instruction manual of the equip-
ment used.
• The unit is compatible with multi-
session recorded discs. However,
be sure to properly close the ses-
sion. Disc with a session that has
not been closed cannot be played
properly. When a disc is initially
inserted, some time will be
required for reading the data before
play can begin.

USB device connection
When connecting a USB device, make
sure that the connector is pushed all the
way into the port.
Do not leave the USB device for long
periods of time in places inside the vehi-
cle where the temperature can rise too
high.
Back up any important data beforehand.
We cannot accept responsibility for any
lost data.
It is recommended not to connect a USB
device that contains data files other than
MP3/WMA/AAC format.
We recommend against use of USB
devices that are non-standard shape
such as key chains, mobile phone
accessories, etc. which may damage or
stress the connection between USB
device and Socket terminal.
Always close the USB socket terminal
when not in use, since entry of foreignmaterial, dust, water, conductive liquids
may damage the audio system or USB
device.
Device such as MP3 player/Mobile
phone/digital camera may not be rec-
ognized by the audio system for playing
music.
Recording MP3/WMA/AAC
files on a USB device
Playback or display may not be possible
depending on the type of USB device in
use or the condition of the recording.
Depending on the connected USB mem-
ory, the files may be played in different
order from the order that the files were
stored.
During initialization, the reading time of
USB device may vary depending upon
factors such as file structure, size and
contents other than music files.
When files recorded contains VBR (vari-
able bit rate), during playback, fast-for-
ward or reverse operation are done.
The sound quality of MP3/WMA/AAC
files generally improves with higher bit
rate in order to achieve good sound qual-
ity recording with CBR 9continuous bit
rate) of at least 128kbps is recom-
mended.
