Safety precautions  
IMPORTANT INFORMATION  
2WARNING  
2CAUTION  
About CD players/disc changers  
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.  
• When extending the ignition, battery, or  
ground wires, make sure to use automotive-  
grade wires or other wires with a 0.75mm2  
(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.  
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.  
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.  
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.  
Unsupported connection may result in  
damage.  
Setting the "O-N" Switch to the "N" position for  
the applicable KENWOOD disc changers/ CD  
players.  
• 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.  
The functions that can be used and the  
information that can be displayed will differ  
depending on the models being connected.  
• Do not subject the faceplate to excessive  
shock, as it is a piece of precision  
equipment.  
You can damage both your unit and the CD  
changer if you connect them incorrectly.  
• 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.  
• 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 a short circuit when replacing a  
fuse, first disconnect the wiring harness.  
• Do not place any object between the  
faceplate and the unit.  
• Do not use your own screws. Use only the  
screws provided. If you use the wrong  
screws, you could damage the unit.

• 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  
The use of any accessories except for those provided might result in  
damage to the unit. Make sure only to use the accessories shipped with  
the unit, as shown above.  
Installation Procedure (KRC-766/666/666G)  
1. To prevent a short circuit, remove the key from the ignition and  
• After the unit is installed, check whether the brake lamps,  
blinkers, wipers, etc. on the car are working properly.  
disconnect the - battery.  
2. Make the proper input and output wire connections for each unit.

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.  
2CAUTION  
• 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.  
The use of any accessories except for those provided might result in  
damage to the unit. Make sure only to use the accessories shipped with  
the unit, as shown above.  
• 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  
Installation Procedure (KRC-666R)  
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 wire on the wiring harness.  
• After the unit is installed, check whether the brake lamps,  
blinkers, wipers, etc. on the car are working properly.  
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.

Connecting Wires to Terminals (KRC-666R)  
When the connection is made as in 3 above, the unit's  
power will not be linked to the ignition key. For that reason,  
always make sure to turn off the unit's power when the  
ignition is turned off.  
To link the unit's power to the ignition, connect the ignition  
cable (ACC...red) to a power source that can be turned on  
and off with the ignition key.  
2WARNING  
Connecting the ISO Connector  
The pin arrangement for the ISO connectors depends on the type  
of vehicle you drive. Make sure to make the proper connections to  
prevent damage to the unit.  
The default connection for the wiring harness is described in 1  
below. If the ISO connector pins are set as described in 2 or 3,  
make the connection as illustrated.  
Please be sure to reconnect the cable as shown 2 below to  
install this unit to the Volkswagen vehicles etc.
