Safety precautions
Cleaning the Faceplate Terminals
If the terminals on the unit or faceplate get
dirty, wipe them with a dry, soft cloth.
Cleaning the Tape Head
NOTE
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.
• 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.
Cleaning the Unit
If the front panel gets dirty, turn off the
power and wipe the panel with a dry silicon
cloth or soft cloth.

Handling Cassette Tapes
DISC
• 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 wipe the panel with a hard cloth or a
cloth dampened by volatile solvents such as
paint thinner and alcohol. They can scratch
the surface of the panel and/or cause the
indicator letters to peel off.

Reset button
• 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.
• 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.

2CAUTION
Battery
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.
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.
