Safety precautions
2WARNING
2CAUTION
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.
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.
• When extending the ignition, battery, or
ground wires, make sure to use automotive-
2
grade 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.
• 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.
• Be careful not to drop the unit or subject it to
strong shock.
• To prevent a short circuit when replacing a
fuse, first disconnect the wiring harness.
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.
• Do not use your own screws. Use only the
screws provided. If you use the wrong
screws, you could damage the unit.
If the liquid crystal fluid from the LCD
contacts your body or clothing, wash it off
with soap immediately.

Safety precautions
Cleaning the Unit
Cleaning the Tape Head
NOTE
If the front panel gets dirty, turn off the
power and wipe the panel with a dry silicon
cloth or soft cloth.
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.
2CAUTION
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.
Handling Cassette Tapes
KRC-108S
• 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.
Reset button
• Characters in the LCD may become difficult
to read in temperatures below 41 ˚F (5 ˚C).
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.
• 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.
• 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.

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.

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.
