2CAUTION
NOTE
• If you experience problems during installa-
tion, consult your Kenwood dealer.
To prevent injury and/ or fire, take the
follow ing precautions:
To prevent dam age to the m achine,
take the follow ing precautions:
• 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.
• 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.
• When extending the ignition, battery or
ground cables, make sure to use automotive-
grade cables or other cables with an area of
0.75mm2 (AWG18) or more to prevent cable
deterioration and damage to the cable coat-
ing.
• 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 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 face-
plate case in areas exposed to direct sunlight,
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.
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.
• Be careful not to drop the unit or subject it to
strong shock.
• To prevent deterioration, do not touch the
terminals of the unit or faceplate with your
fingers.
• 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 mal-
function.
• To prevent short circuits when replacing a
fuse, first disconnect the wiring harness.
• 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.
The unit may break or crack because it con-
tains glass parts.
• Do not touch the liquid crystal fluid if the LCD
is damaged or broken due to shock. The liq-
uid crystal fluid may be dangerous to your
health or even fatal.
If the liquid crystal fluid from the LCD con-
tacts your body or clothing, wash it off with
soap immediately.
2CAUTION
Do not wipe the panel with a stiff 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.
Cleaning the Faceplate Term inals
If the terminals on the unit or faceplate get
dirty, wipe them with a dry, soft cloth.

Cleaning the Tape Head
Ba s ic o p e ra t io n s
After you have used the tape player many times over a long period,
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 cap-
stan and/or pinch rollers, causing trouble.

LOUD
• 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 above the fascia panel
(dashboard) and other spots exposed to direct sunlight, or near
heater outlets. They can deform the cassette.
ATT
LOUD
• 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
whilst. If you leave a tape in the unit too long, it may stick to the tape
head and cause unit malfunction.

In s t a lla t io n P ro c e d u re
1. To prevent short circuits, remove the key from the ignition and
2CAUTION
disconnect the -terminal of the battery.
• If your car is not prepared for this special connection-system,
consult your kenwood dealer.
• Only use antenna conversion adapters (ISO-JASO) when the
antenna cord has an ISO plug.
• Make sure that all cable 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 cable is connected to a power source with constant
voltage such as a battery cable, 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 cable to a power source that can be turned
on and off with the ignition key.
2. Make the proper input and output cable connections for each unit.
3. Connect the cable on the wiring harness.
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.
• If the fuse blows, first make sure that the cables have not
caused a short circuit, then replace the old fuse with one with
the same rating.
• Do not let unconnected cables or terminals touch metal on the
car or anything else conducting electricity. To prevent short cir-
cuits, also do not remove the caps on the ends of the uncon-
nected cables or the terminals.
• Connect the speaker cables correctly to the terminals to which
they correspond. The unit may receive damage or fail to work if
you share the - cables and/or ground them to any metal part in
the car.
• After the unit is installed, check whether the brake lamps, indi-
cators, wipers, etc. on the car are working properly.
• Some disc changers need conversion cables for connection.
See the section on "Safety Precautions" for details.
• Insulate unconnected cables with vinyl tape or other similar
material.
