IMPORTANT INFORMATION  
2WARNING  
2CAUTION  
About CD players/disc changers  
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.  
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.  
• 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 use your own screws. Use only the  
screws provided. If you use the wrong  
screws, you could damage the unit.  
connected to this unit  
KENWOOD disc changers/ CD players  
released in 1998 or later can be connected to  
this unit.  
Refer to the catalog or consult your Kenwood  
dealer for connectable models of disc  
changers/ CD players.  
Note that any KENWOOD disc changers/ CD  
players released in 1997 or earlier and disc  
changers made by other makers cannot be  
connected to this unit.  
Unsupported connection may result in  
damage.  
Setting the "O-N" Switch to the "N" position for  
the applicable KENWOOD disc changers/ CD  
players.  
• 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.  
The functions that can be used and the  
information that can be displayed will differ  
depending on the models being connected.  
You can damage both your unit and the CD  
changer if you connect them incorrectly.  
• 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.  
Do Not Load 3-in. CDs in the CD slot  
If you try to load a 3 in. 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.

to read in temperatures below 41 ˚F (5 ˚C).  
• The illustrations of the display and the panel  
appearing in this manual are examples used  
to explain more clearly how the controls are

the display may represent something  
impossible in actual operation.  
Lens Fogging  
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.

Notes on playing MP3 (DPX-MP4050B/ DPX-MP4050/ DPX-MP4030)  
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.  
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.  
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 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 File Search or Folder Search may not be performed smoothly.  
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  
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.  
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 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.

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.  
• 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  
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.  
• 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.  
4. Connect the wiring harness wires in the following order: ground,  
battery, ignition.  
5. Connect the wiring harness connector to the unit.  
6. Install the unit in your car.  
7. Reconnect the - battery.
