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".  
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 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 an area of  
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.  
• 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 moving  
faceplate. Doing so will cause damage or  
malfunction.  
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.  
• Do not apply excessive force to the open  
faceplate or place objects on it. Doing so will  
cause damage or breakdown.

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.
