IMPORTANT INFORMATION  
2WARNING  
2CAUTION  
About CD players/disc changers  
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.  
• 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.  
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.  
• 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 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.

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.

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.  
When using the unit for the first time  
In order to deactivate the demonstration  
mode. Transmit the Mask Key's signal. (page  
30)  
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.  
• Press the reset button if the Disc auto  
changer fails to operate correctly. Normal  
operation should be restored.  
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.  
Cleaning the CD Slot  
As dust can accumulate in the CD slot, clean it  
occasionally. Your CDs can get scratched if  
you put them in a dusty CD slot.  
Reset button  
• If you send products in for repair that include  
a mask key, make sure to present the unit  
together with the mask key.

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/WMA(KDC-PSW9521)/ MP3(KDC-M9021SE/KDC-M9021)  
This unit can play MP3(MPEG1, 2, 2.5 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.  
Entering ID3 tag and Contents  
Description  
The Displayable ID3 tag is ID3 version  
1.x.  
For the character code, refer to the List  
of Codes.  
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.  
Entering file and folder names  
The code list characters are the only file  
Acceptable medium formats  
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 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.  
The unit recognizes and plays only those MP3/WMA which have the  
MP3/WMA extension (.MP3/.WMA).  
• 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/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 Track Search or Album Search may not be  
performed smoothly.  
MP3/WMA written in the formats other than the above may not be  
successfully played and their file names or folder names are not  
properly displayed.  
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.  
Settings for your MP3/WMA encoder and CD writer  
Do the following setting when compressing audio data in WMA data  
with the WMA encoder.  
• Transfer bit rate: 64k —192 kbps  
• Do not attempt to play a medium containing non MP3/WMA.  
• Sampling frequency: 32k, 44.1k, 48k Hz  
When you use your CD writer to record MP3/WMA 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.
