Safety precautions

2WARNING

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 automotive­grade 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.

If the liquid crystal fluid from the LCD
contacts your body or clothing, wash it off
with soap immediately.

2

2CAUTION

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.

• To prevent a short circuit when replacing a
fuse, first disconnect the wiring harness.

• 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.

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 CA­DS100 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.

2CAUTION

You can damage both your unit and
the CD changer if you connect them
incorrectly.

Safety precautions

NOTE

• If you experience problems during
installation, consult your Kenwood dealer.

English

• 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.

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.

Cleaning the Faceplate Terminals

If the terminals on the unit or faceplate get
dirty, wipe them with a dry, soft cloth.

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.

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.

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.

Cleaning the Tape Head

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.

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.

• 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.

4. Connect the wiring harness wires in the following order: ground,
battery, ignition.

5. Connect the wiring harness connector to the unit.

6. Install the unit in your car.

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 aren’t 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.
