About CD players/disc changers  
connected to this unit  
Kenwood disc changers/ CD players released in  
1998 or later can be connected to this unit.  
Refer to the catalog or consult your Kenwood  
dealer for connectable models of disc changers/  
CD players.  
2WARNING  
To prevent injury or fire, take the  
following precautions:  
• To prevent a short circuit, never put or leave any  
metallic objects (such as coins or metal tools)  
inside the unit.  
Note that any Kenwood disc changers/ CD players  
released in 1997 or earlier and disc changers made  
by other makers cannot be connected to this unit.  
Connecting unsupported disc changers/CD players  
to this unit may result in damage.  
Set the "O-N" Switch to the "N" position for the  
applicable Kenwood disc changers/ CD players.  
The functions you can use and the information  
that can be displayed may differ depending on the  
models being connected.  
• Mounting and wiring this product requires  
skills and experience. For safety’s sake, leave the  
mounting and wiring work to professionals.  
Attach the panel while you are on the  
vehicle  
The panel lock arm appears when the panel is  
removed. Therefore, the panel must be attached  
while the electrical system of the car is operating.  
2CAUTION  
•
You can damage both your unit and the CD changer if  
you connect them incorrectly.  
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 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 place the faceplate (and 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.  
Lens Fogging  
When 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, this  
condensation on the lens may not allow CDs 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.  
• 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 fuse with  
the prescribed rating. Using a fuse with the wrong  
rating may cause your unit to malfunction.  
• Do not apply excessive force to the open  
faceplate or place objects on it. Doing so will  
cause damage or breakdown.  
• Do not use your own screws. Use only the screws  
provided. If you use the wrong screws, you could  
damage the unit.  
Do Not Load 8 cm (3 in.) CDs in the CD  
slot  
If you try to load a 8 cm (3 in.) CD with its adapter  
into the unit, the adapter might separate from the  
CD and damage the unit.

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.  
•
If the power is not turned ON (or it is ON, but will be OFF  
immediately), the speaker wire may have a short-circuit  
or touched the chasis of the vehicle and the protection  
function may have been activated. Therefore, the speaker  
wire should be checked.  
•
If your car’s ignition does not have an ACC position,  
connect the ignition wires to a power source that can be  
turned on and off with the ignition key. If you connect  
the ignition wire to a power source with a constant  
voltage supply, as with battery 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.  
Insulate unconnected wires with vinyl tape or other  
similar material. 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.  
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.  
7
..........1  
•
•
After the unit is installed, check whether the brake lamps,  
blinkers, wipers, etc. on the car are working properly.  
Mount the unit so that the mounting angle is 30° or less.  
Installation Procedure  
1. To prevent a short circuit, remove the key from  
the ignition and disconnect the - battery.  
2. Make the proper input and output wire  
connections for each unit.  
3. Connect the speaker wires of the wiring harness.  
4. Connect the wiring harness wires in the  
following order: ground, battery, ignition.
