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.  
Unsupported connection may result in damage.  
Setting the "O-N" Switch to the "N" position for the  
applicable KENWOOD disc changers/ CD players.

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 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,

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.  
• 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.  
• Do not apply excessive force to the open  
faceplate or place objects on it. Doing so will  
cause damage or breakdown.

Accessories/ Installation Procedure  
Accessories  
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.  
1
..........1  
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.  
2
Make sure that all wire connections are securely made by  
inserting jacks until they lock completely.  
..........2  
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.  
3
..........1  
4
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.  
..........1  
Installation Procedure  
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.  
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.  
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.
