Safety precautions

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

automotive-grade wires or other wires with

a 0.75mm2 (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.

2WARNING

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.

·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.

· Do not apply excessive force to the open

faceplate or place objects on it. Doing so

will cause damage or breakdown.

2CAUTION

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.

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, 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.

You can damage both your unit and

the CD changer if you connect them

incorrectly.

The marking of products using lasers

(Except for some areas)

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.

· If you experience problems during

installation, consult your Kenwood dealer.

· If the unit fails to operate properly, press

the RESET button. The unit returns to

factory settings when the RESET button is

pressed. If the unit still fails to operate

properly after the RESET button has been

pressed, contact your local KENWOOD

dealer for assistance.

·Press the reset button if the disc auto

changer is first controlled and operates

incorrectly. The original operating condition

will return.

· 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 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.

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.

Cleaning the CD Slot

As dust tends to accumulate in the CD slot,

clean it every once in a while. Your CDs can

get scratched if you put them in a dusty CD

slot.

Lens Fogging

Right after you turn on the car heater in cold

weather, dew or condensation may form on

the lens in the CD player of the unit. Called

lens fogging, CDs may be impossible to play.

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.

2CAUTION

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.

Handling Compact discs

Playing a CD that is dirty, scratched

or warped can cause the sound to

skip and the unit to operate

incorrectly, resulting in worsened

sound quality. Take the following

precautions to prevent your CDs from

getting scratched or damaged.

Handling CDs

· Do not touch the recorded side of the CD

(the side opposite the label) when holding

it.

· The reflective film on a CD-R or a CD-RW is

more fragile than that on an ordinary music

CD, and may peel off if scratched. Fingerprints

on a CD-R or CD-RW are also more likely to

cause skipping when the disc is played. For

these reasons, handle the disc very carefully.

Detailed handling instructions will appear on

the CD-R or CD-RW package: read this

information carefully before using the disc.

· Do not stick tape on either side of the CD.

Storing CDs

·Do not store CDs in areas exposed to

direct sunlight (such as a car seat or the

dashboard) or other hot places. A CD-R or

CD-RW is more susceptible than a music

CD to damage from high temperatures and

humidity, and in some cases, may become

unusable if left in the car for long periods

of time.

· Remove CDs from the unit when not

listening to them for a while, and put them

back in their cases. Do not pile up CDs

that are removed from their cases or prop

them against something.

Cleaning CDs

If a CD has gotten dirty, wipe it off gently

using a commercially available cleaning cloth

or a soft cotton cloth, starting from the

center of the disc and moving outward. Do

not clean CDs with conventional record

cleaners, anti-static formulas, or chemicals

such as paint thinner or benzene.

Checking New CDs for Burrs

When playing a new CD for the first time,

check that there are not any burrs stuck to

the perimeter of the disc or in the central

hole. CDs with burrs stuck on them may not

load properly or may skip while playing.

Remove burrs using a ballpoint pen or a

similar utensil.
