Safety precautions
IMPORTANT INFORMATION
About the disc changer/CD player to
be connected:
2WARNING
2CAUTION
To prevent injury and/or fire, take the
following precautions:
• Insert the unit all the way until it is fully
locked in place. Otherwise it may fly out of
place during collisions and other jolts.
• 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 short circuits, never put or leave
any metallic objects (e.g., coins or metal
tools) inside the unit.
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 subject the faceplate to excessive
shock, as it is a piece of precision
equipment.
To connect a disc changer having the "O-N"
switch to this unit, set the "O-N" switch to "N".
To connect a disc changer having no "O-N"
switch to this unit, the converter cord CA-
DS100 and/or switching adapter KCA-S210A
are required as options.
A disc changer doesn't work when it is
connected without using these options.
If a model with no "O-N" switch is connected,
some unavailable functions and information
that cannot be displayed are generated.
Note that none of the KDC-C100, KDC-C302,
C205, C705, and non-Kenwood CD changers
can be connected.
• 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.
• If the unit starts to emit smoke or strange
smells, turn off the power immediately and
consult your Kenwood dealer.
You can damage both your unit and the CD
changer if you connect them incorrectly.
• 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.
• To prevent short circuits when replacing a
fuse, first disconnect the wiring harness.
• Do not place any object between the
faceplate and the unit.
• During installation, do not use any screws
except for the ones provided. The use of
improper screws might result in damage to
the main unit.
• Do not apply excessive force to the open
faceplate or place objects on it. Doing so will
cause damage or breakdown.
Do Not Load 8-cm (3-in.) CDs in the CD
slot
If you try to load an 8-cm CD with its adapter
into the unit, the adapter might separate from
the CD and damage the unit.
If the liquid crystal fluid from the LCD
contacts your body or clothing, wash it off
with soap immediately.

Safety precautions
• The illustrations of the display and the panel
appearing in this manual are examples used
to explain more clearly how the controls are
used. Therefore, what appears on the display
in the illustrations may differ from what
appears on the display on the actual
equipment, and some of the illustrations on
the display may represent something
impossible in actual operation.
Cleaning the Faceplate Terminals
If the terminals on the unit or faceplate get
dirty, wipe them with a dry, soft cloth.
NOTE
• If you experience problems during
installation, consult your Kenwood dealer.
• If the unit fails to operate properly, press the
Reset button. The unit returns to factory
settings when the Reset button is pressed.
After you press the reset button, the Mask
Key will be needed to restart the unit. If the
unit still fails to operate properly after the
Reset button has been pressed, contact your
local KENWOOD dealer for assistance.
Cleaning the Unit
If the faceplate of this unit is stained, wipe it
with a dry soft cloth such as a silicon cloth.
If the faceplate is stained badly, wipe the stain
off with a cloth moistened with neutral
cleaner, then wipe neutral detergent off.
Lens Fogging
Applying spray cleaner directly to the unit may
affect its mechanical parts. Wiping the
faceplate with a hard cloth or using a volatile
liquid such as thinner or alcohol may scratch
the surface or erases characters.
Right after you turn on the car heater in cold
weather, dew or condensation may form on
the lens in the CD player of the unit. Called
lens fogging, CDs may be impossible to play.
In such a situation, remove the disc and wait
for the condensation to evaporate. If the unit
still does not operate normally after a while,
consult your Kenwood dealer.
• Press the reset button if the Disc auto
changer fails to operate correctly. Normal
operation should be restored.

About RDS
The marking of products using lasers
(Except for some areas)
RDS (Radio Data System)
When listening to an RDS station, the program
service name of the station is displayed,
advising you quickly which station is being
received.
CLASS 1
LASER PRODUCT
RDS (Radio Data System) stations also
transmit alternative frequency data for the
same station. When you are making long trips,
this function automatically switches to the
particular frequency with the best reception
for the particular network of stations that you
want to listen to. The data is automatically
stored, allowing you to switch quickly to
another RDS stations, broadcasting the same
program, that has better reception. These
include stations stored in the station preset
memory that you often listen to.
The label is attached to the chassis/case and
says that the component uses laser beams
that have been classified as Class 1. It means
that the unit is utilizing laser beams that are of
a weaker class. There is no danger of
hazardous radiation outside the unit.
Enhanced Other Network
Stations that offer <Enhanced Other
Network> also transmit information about
other RDS stations that have traffic
information. When you are tuned to a station
that is not transmitting traffic information, but
another RDS station starts transmitting a
traffic bulletin, the tuner automatically
switches to the other station for the duration
of the bulletin.
Alarm
When an emergency transmission (announcing
disasters, etc.) is sent, all current functions are
interrupted to allow the warning to be
received.

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.
Entering ID3 tag
The Displayable ID3 tag is ID3 version
1.x.
For the character code, refer to the
List of Codes.
Acceptable media
The MP3 recording media acceptable to this unit are CD-ROM, CD-R,
Entering file and folder names
The code list characters are the only
file names and folder names that can
be entered and displayed.
and CD-RW.
When using CD-RW, do full format not quick format to prevent
malfunction.
If you use any other character for
Acceptable medium formats
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).
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)
A file with a name entered with characters not on the code list may not
play correctly.
• Romeo (128 characters)
Writing files into a medium
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
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 non-
MP3 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 Track Search or Album 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 file with
the MP3 extension.
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.
The unit mistakes non-MP3 files for MP3 data as long as they
have the MP3 extension.
• Do not attempt to play a medium containing non MP3.
Settings for your MP3 encoder and CD writer
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.
