IMPORTANT INFORMATION
About the disc changer/CD player to
be connected:
To connect a disc changer having the "O-N"
switch to this unit, set the "O-N" switch to "N".
When you connect a model with no "O-N"
switch, the converter cord CA-DS100 available
as an option may be required. For details,
consult your Kenwood dealer.
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.
2WARNING
2CAUTION
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 0.75mm
(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.
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.
2
• 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.
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.
• 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 use your own screws. Use only the
screws provided. If you use the wrong
screws, you could damage the unit.

Notes on playing MP3 (KDC-Z838)
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,
and CD-RW.
Entering file and folder names
When using CD-RW, do full format not quick format to prevent
malfunction.
The code list characters are the only
file names and folder names that can
be entered and displayed.
Acceptable medium formats
If you use any other character for
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.
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).
• ISO 9660 Level 1 (12 characters)
• ISO 9660 Level 2 (31 characters)
• Joliet (64 characters)
• Romeo (128 characters)
A file with a name entered with characters not on the code list
may not play correctly.
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
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 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.
The unit mistakes non-MP3 files for MP3 data as long as they have
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.
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.
• Do not attempt to play a medium containing non MP3.

2CAUTION
• If your car's ignition does not have an ACC position, connect the
ignition wires to a power source that can be turned on and off
with the ignition key. If you connect the ignition wire to a power
source with a constant voltage supply, as with battery wires, the
battery may die.
• If the console has a lid, make sure to install the unit so that the
faceplate will not hit the lid when closing and opening.
• If the fuse blows, first make sure the wires aren’t touching to
cause a short circuit, then replace the old fuse with one with the
same rating.
• Insulate unconnected wires with vinyl tape or other similar
material. To prevent a short circuit, do not remove the caps on
the ends of the unconnected wires or the terminals.
• Connect the speaker wires correctly to the terminals to which
they correspond. The unit may be damaged or fail to work if you
share the - wires or ground them to any metal part in the car.
• When only two speakers are being connected to the system,
connect the connectors either to both the front output terminals
or to both the rear output terminals (do not mix front and rear).
For example, if you connect the + connector of the left speaker
to a front output terminal, do not connect the - connector to a
rear output terminal
The use of any accessories except for those provided might result in
damage to the unit. Make sure only to use the accessories shipped with
the unit, as shown above.
Installation Procedure
1. To prevent a short circuit, remove the key from the ignition and
disconnect the - battery.
2. Make the proper input and output wire connections for each unit.
3. Connect the speaker wires of the wiring harness.
4. Connect the wiring harness wires in the following order: ground,
battery, ignition.
• After the unit is installed, check whether the brake lamps,
blinkers, wipers, etc. on the car are working properly.
• Mount the unit so that the mounting angle is 30° or less.
5. Connect the wiring harness connector to the unit.
6. Install the unit in your car.
7. Reconnect the - battery.
8. Press the reset button.
