To prevent injury and/or fire, take the
following precautions:
•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 wires, make sure to use automotive-
grade wires or other wires with an area of
0.75mm2(AWG18) or more to prevent wire
deterioration and damage to the wire
coating.
•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 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.
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 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 short circuits when replacing a
fuse, first disconnect the wiring harness.
•Do not place any object between the
faceplate and the unit.
•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.
2CAUTION Do Not Load 8-cm (3-in.) CDs in the CD
slot
If you try to load an 8-cm CD with its adapter
into the unit, the adapter might separate from
the CD and damage the unit.

•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.
•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.
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 whilst,
consult your Kenwood dealer.
NOTE 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.
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 can accumulate in the CD slot, clean it
occasionally. Your CDs can get scratched if
you put them in a dusty CD slot.
Safety precautions
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.
This Product is not installed by the
manufacturer of a vehicle on the production
line, nor by the professional importer of a
vehicle into an EU Member State.

1. To prevent short circuits, remove the key from the ignition and
disconnect the - terminal of the battery.
2. Make the proper input and output wire connections for each unit.
3. Connect the wire 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 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 wire 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 wire is connected to a power source with constant
voltage such as a battery wire, 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 wire to a power source that can be turned
on and off with the ignition key.
•If the fuse blows, first make sure that the wires have not caused
a short circuit, then replace the old fuse with one with the same
rating.
•Insulate unconnected wires with vinyl tape or other similar
material. To prevent short circuits, also 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 receive damage or fail to work if
you share the -wires and/or ground them to any metal part in
the car.
•After the unit is installed, check whether the brake lamps,
indicators, wipers, etc. on the car are working properly.
•If the console has a lid, make sure to install the unit so that the
faceplate does not hit the lid when closing and opening.
•Mount the unit so that the mounting angle is 30° or less.
