IMPORTANT INFORMATION  
About the disc changer to be  
connected:  
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.  
If a model with no "O-N" switch is  
connected, some unavailable functions and  
information that cannot be displayed are  
generated, such as the DNPS, DNPP,  
Magazine random play, and CD Text display.  
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.  
• 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 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.  
2
2CAUTION  
You can damage both your unit and  
the CD changer if you connect them  
incorrectly.  
• To prevent a short circuit when replacing a  
fuse, first disconnect the wiring harness.  
If the liquid crystal fluid from the LCD  
contacts your body or clothing, wash it off  
with soap immediately.  
• 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.

Safety precautions  
Cleaning the Faceplate Terminals  
If the terminals on the unit or faceplate get  
dirty, wipe them with a dry, soft cloth.  
Cleaning the Tape Head  
NOTE  
After you have listened to many cassettes  
over a long period of time, magnetic powder  
from the tapes and dust accumulates on the  
tape head, causing noise and a deterioration  
in sound quality. Clean the tape head using a  
cleaning tape or cleaning kit designed for use  
in car audio systems.  
• If you experience problems during  
installation, consult your Kenwood dealer.  
• If the unit does not seem to be working  
right, try pressing the reset button first. If  
that does not solve the problem, consult  
your Kenwood dealer.  
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.  
Handling Cassette Tapes  
• Do not play a cassette whose tape has gone  
slack. In such a case, wind it tight using a  
pencil or the like in one of the spools.  
Playing slack cassette tapes can result in the  
tape tangling around the capstan and/or  
pinch rollers, causing trouble.  
• Do not play a deformed cassette or one  
whose label is starting to come off, as it can  
cause the unit to malfunction.  
• Do not leave tapes in hot places, such as on  
dashboards and other spots exposed to  
direct sunlight, or near heater outlets. They  
can deform the cassette.  
• Avoid using extremely long cassette tapes,  
such as 100-minute-long tapes. Such tapes  
are very thin, and can tangle easily around  
the pinch rollers or other parts inside the  
unit, causing unit failure.  
2CAUTION  
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.  
Reset button  
• Characters in the LCD may become difficult  
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  
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.  
• The functions that can be used and the  
information that can be displayed will differ  
depending on the external disc players being  
connected.  
FCC WARNING  
This equipment may generate or use radio  
frequency energy. Changes or modifications  
to this equipment may cause harmful  
interference unless the modifications are  
expressly approved in the instruction manual.  
The user could lose the authority to operate  
this equipment if an unauthorized change or  
modification is made.  
• Remove a cassette tape from the unit when  
not listening to it for a while. If you leave a  
tape in the unit too long, it may stick to the  
tape head and cause unit malfunction.

7. Reconnect the - battery.  
8. Press the reset button.  
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 arent touching to  
cause a short circuit, then replace the old fuse with one with  
the same rating.  
Do not let unconnected wires or terminals touch metal on the  
car or anything else conducting electricity. 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.  
After the unit is installed, check whether the brake lamps,  
blinkers, wipers, etc. on the car are working properly.  
Insulate unconnected wires with vinyl tape or other similar  
material.  
Some disc changers need conversion cords for connection. See  
the section on "Safety Precautions" for details.  
2CAUTION  
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.

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.  
2WARNING  
If you connect the ignition wire (red) and the battery wire  
(yellow) to the car chassis (ground), you may cause a short  
circuit, that in turn may start a fire. Always connect those  
wires to the power source running through the fuse box.
