Safety precautions

2WARNING

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 automotive-grade wires
or other wires with a 0.75mm² (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.

2CAUTION

To prevent damage to the machine, take
the following precautions:

• Make sure to ground the unit to a negative 12V
DC power supply.

• Do not open the top or bottom covers of the unit.

• Do not install the unit in a spot exposed to direct
sunlight or excessive heat or humidity. Also avoid
places with too much dust or the possibility of
water splashing.

• Do not set the removed faceplate or the faceplate
case in areas exposed to direct 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 with
the prescribed rating. Using a fuse with the wrong
rating may cause your unit to malfunction.

• To prevent a short circuit when replacing a fuse,
first disconnect the wiring harness.

• Do not place any object between the faceplate
and the unit.

• Do not apply excessive force to the moving
faceplate. Doing so will cause damage or
malfunction.

• Do not apply excessive force to the open
faceplate or place objects on it. Doing so will
cause damage or breakdown.

Audio Layer 3)/WMA. Note, however, that the MP3/
WMA recording media and formats acceptable are
limited. When writing MP3/WMA, pay attention to
the following restrictions.

Acceptable media

The MP3/WMA 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 and folder 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 character;Up to 32 characters are

• Romeo (128 character; Up to 64 characters are

• Long file name (200 characters; Up to 64

• Maximum number of characters for folder name:

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 folders: 50
MP3/WMA written in the formats other than the

audio data in MP3/WMA data with the MP3/WMA
encoder.

• Transfer bit rate: MP3: 8 —320 kbps

English

• Play mode may not be possible when portions of the
functions of Windows Media Player 9 or higher are used.

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/WMA
which have the MP3/WMA extension (.MP3/.WMA).

• 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/WMA data is
loaded, the unit checks all the data on the medium.
If the medium contains a lot of folders or non-MP3/
WMA files, therefore, it takes a long time until the
unit starts playing MP3/WMA.
In addition, it may take time for the unit to move
to the next MP3/WMA 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.

• Do no attempt to play a medium containing a non-MP3/
WMA file with the MP3/WMA extension.
The unit mistakes non-MP3/WMA files for MP3/WMA data
as long as they have the MP3/WMA extension.

• Do not attempt to play a medium containing non MP3/
WMA.

MP3/WMA playing order

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/WMA 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.
