IMPORTANT INFORMATION
About the disc changer/CD player 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.
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 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.
• 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.
You can damage both your unit and the CD
changer if you connect them incorrectly.
• 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.
• 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.
If the liquid crystal fluid from the LCD
contacts your body or clothing, wash it off
with soap immediately.
• 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.

• Don’t use deformed cassette tape.
• Don’t place cassette tape on the dashboard
etc. where the temperature is high.
• Don’t use cassette tape that’s 100 minutes

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.

2CAUTION
..........................................2
..........................................1
• 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.
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.
• If the fuse blows, first make sure that the wires have not caused
a short circuit, then replace the old fuse with one with the same
rating.
• 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.
• 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 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. Cars with an ISO connector:
Connect the speaker connector of the car to Connector B of the
unit, and then connect the external power connector to
Connector A.
Cars without an ISO connector:
First connect the wire of the wiring harness, and then connect
the wiring harness connector to the unit.
• 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.
4. Install the unit in your car.
5. Reconnect the - terminal of the battery.
6. Press the reset button.
