To prevent injury or fire, take the
following precautions:
• Insert the unit all the way in until it is fully
locked in place. Otherwise it may fall out of
place when jolted.
• When extending the ignition, battery, or
ground wires, make sure to use automotivegrade wires or other wires with a 0.75mm
(AWG18) or more to prevent wire
deterioration and damage to the wire
coating.
•To prevent a short circuit, never put or leave
any metallic objects (such as coins or metal
tools) inside the unit.
• If the unit starts to emit smoke or strange
smells, turn off the power immediately and
consult your Kenwood dealer.
• Make sure not to get your fingers caught
between the faceplate and the unit.
• Be careful not to drop the unit or subject it to
strong shock.
The unit may break or crack because it
contains glass parts.
• Do not touch the liquid crystal fluid if the
LCD is damaged or broken due to shock. The
liquid crystal fluid may be dangerous to your
health or even fatal.
If the liquid crystal fluid from the LCD
contacts your body or clothing, wash it off
with soap immediately.

sunlight, excessive heat or humidity. Also
avoid places with too much dust or the
possibility of water splashing.
•To prevent deterioration, do not touch the
terminals of the unit or faceplate with your
fingers.
• Do not subject the faceplate to excessive
shock, as it is a piece of precision
equipment.
• When replacing a fuse, only use a new one

Notes on playing MP3
This unit can play MP3(MPEG1, 2, 2.5 Audio Layer 3). Note,
however, that the MP3 recording media and formats acceptable
are limited. When writing MP3, pay attention to the following
restrictions.
English
Acceptable media
The MP3 recording media acceptable to this unit are CD-ROM, CD-R,
and CD-RW.
When using CD-RW, do full format not quick format to prevent
malfunction.
Acceptable medium formats
The following formats are available for the media used in this unit. The
maximum number of characters used for file name including the
delimiter (".") and three-character extension are indicated in
parentheses.
• ISO 9660 Level 1 (12 characters)
• ISO 9660 Level 2 (31 characters)
• Joliet (64 characters)
• Romeo (128 characters)
Up to 200 characters can be displayed in the long file name format.
For a list of available characters, see the instruction manual of the
writing software and the section Entering file and folder names below.
The media reproducible on this unit has the following limitations:
• Maximum number of directory levels: 8
• Maximum number of files per folder: 255
• Maximum number of characters for folder name: 64
• Maximum number of folders: 50
MP3 written in the formats other than the above may not be
successfully played and their file names or folder names are not
properly displayed.
Settings for your MP3 encoder and CD writer
Do the following setting when compressing audio data in MP3 data
with the MP3 encoder.
•Transfer bit rate : 8 — 320 kbps
• Sampling frequency : 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 kHz
When you use your CD writer to record MP3 up to the maximum disc
capacity, disable additional writing. For recording on an empty disc up
to the maximum capacity at once, check Disc at Once.
Entering ID3 tag
The Displayable ID3 tag is ID3 version 1.x.
For the character code, refer to the List of Codes.
Entering file and folder names
The code list characters are the only
file names and folder names that can
be entered and displayed.
If you use any other character for
entry, the file and folder names are
not displayed correctly. They may
neither be displayed correctly
depending on the CD writer used.
The unit recognizes and plays only
those MP3 which have the MP3
extension (MP3).
A file with a name entered with characters not on the code list may not
play correctly.
Writing files into a medium
When a medium containing MP3 data is loaded, the unit checks all the
data on the medium. If the medium contains a lot of folders or nonMP3 files, therefore, it takes a long time until the unit starts playing
MP3.
In addition, it may take time for the unit to move to the next MP3 file
or a File Search or Folder Search may not be performed smoothly.
Loading such a medium may produce loud noise to damage the speakers.

When selected for play, Folder Search, File Search, or for Folder
Select, files and folders are accessed in the order in which they were
written by the CD writer.
Because of this, the order in which they are expected to be played
may not match the order in which they are actually played. You may be
able to set the order in which MP3 are to be played by writing them
onto a medium such as a CD-R with their file names beginning with
play sequence numbers such as "01" to "99", depending on your CD
writer.
For example, a medium with the following folder/ file hierarchy is
subject to Folder Search, File Search, or Folder Select as shown below.
When a File Search is executed with file ¡$ being played ...
When a Folder Search is executed with file ¡$ being played ...
When Folder Select is selected with file ¡$ being played to move
from folder to folder ...
