Safety precautions
IMPORTANT INFORMATION
About the disc changer to 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.
To prevent damage to the machine,
take the following precautions:
• Make sure to ground the unit to a negative
12V DC power supply.
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.
• 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.
• To prevent short circuits when replacing a
fuse, first disconnect the wiring harness.
• Do not place any object between the
faceplate and the unit.
• When extending the ignition, battery or
ground wires, make sure to use automotive-
grade wires or other wires with an area of
2
0.75mm (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.
• 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.
You can damage both your unit and the CD
changer if you connect them incorrectly.
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.
• 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.

you put them in a dusty CD slot.
• 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.

About RDS
About CDs
RDS (Radio Data System)
Handling CDs
• Don’t touch the recording surface of the CD.
CD cleaning
Clean from the center of the disc and move
outward.
When listening to an RDS station, the
programme service name of the station is
displayed, advising you quickly which station
is being received.
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 programme, that has better
reception. These include stations stored in the
station preset memory that you often listen
to.
Removing CDs
When removing CDs from this unit pull them
out horizontally.
• CD-R and CD-RW are easier to damage than
a normal music CD. Use a CD-R or a CD-RW
after reading the caution items on the
package etc.
• Don’t stick tape etc. on the CD.
Also, don’t use a CD with tape stuck on it.
CDs that can’t be used
• CDs that aren’t round can’t be used.
When using a new CD
If the CD center hole or outside rim has burrs,
use it after removing them with a ball pen etc.
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.
• CDs with coloring on the recording surface
or that are dirty can’t be used.
• Don’t use CDs without disc mark
.
Burrs
• A CD-R or CD-RW that hasn’t been finalized
can’t be played. (For the finalization process
refer to your CD-R/CD-RW writing software,
and your CD-R/CD-RW recorder instruction
manual.)
Burrs
Alarm
When an emergency transmission
(announcing disasters, etc.) is sent, all current
functions are interrupted to allow the warning
to be received.
CD storage
• Don’t place them in direct sunlight (On the
seat or dashboard etc.) and where the
temperature is high.
CD accessories
Don’t use disc type accessories.
• Store CDs in their cases.

• 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.

• 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.
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.
• 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.
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.
• Mount the unit so that the mounting angle is 30° or less.
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 reset button.
