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.

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

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.

• If your car is not prepared for this special connection-system,
consult your KENWOOD dealer.
• Only use antenna conversion adapters (ISO-JASO) when the
antenna cord has an ISO plug.
• Make sure that all wire connections are securely made by
inserting jacks until they lock completely.
• If your vehicle's ignition does not have an ACC position, or if the
ignition wire is connected to a power source with constant
voltage such as a battery wire, the power will not be linked with
the ignition (i.e., it will not turn on and off along with the
ignition). If you want to link the unit's power with the ignition,
connect the ignition wire to a power source that can be turned
on and off with the ignition key.

• Insulate unconnected wires with vinyl tape or other similar
material. To prevent short circuits, also 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 receive damage or fail to work if
you share the - wires and/or ground them to any metal part in
the car.
• After the unit is installed, check whether the brake lamps,
indicators, wipers, etc. on the car are working properly.
• If the console has a lid, make sure to install the unit so that the
faceplate does not hit the lid when closing and opening.
• Mount the unit so that the mounting angle is 30° or less.
Installation Procedure
1. To prevent short circuits, remove the key from the ignition and
disconnect the - terminal of the battery.
2. Make the proper input and output wire connections for each unit.
3. Connect the wire on the wiring harness.
4. Take Connector B on the wiring harness and connect it to the
speaker connector in your vehicle.
5. Take Connector A on the wiring harness and connect it to the
external power connector on your vehicle.
6. Connect the wiring harness connector to the unit.
7. Install the unit in your car.
8. Reconnect the - terminal of the battery.
9. Press the left part at the upper side of the faceplate once to
