IMPORTANT INFORMATION  
2WARNING  
2CAUTION  
About CD players/disc changers  
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.  
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 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.

About Cassette tape  
About RDS  
Cleaning the tape head  
When there’s noise or the sound quality is bad  
during tape play the tape head maybe dirty,  
clean the tape head.  
RDS (Radio Data System)  
When listening to an RDS station, the  
programme service name of the station is  
displayed, advising you quickly which station is  
being received.  
RDS (Radio Data System) stations also  
transmit frequency data for the same station.  
When you are making long trips, this function  
automatically alternative switches to the  
particular frequency with the best reception  
for the particular network of stations that you  
want to listen to. The data is automatically  
stored, allowing you to switch quickly to  
another RDS stations, broadcasting the same  
programme, that has better reception. These  
include stations stored in the station preset  
memory that you often listen to.  
About Cassette tape  
• If the tape is slack tighten it.  
• If the cassette tape label is peeling off glue it  
on again.  
• Don’t use deformed cassette tape.  
• Don’t place cassette tape on the dashboard  
etc. where the temperature is high.  
• Don’t use cassette tape that’s 100 minutes  
long or longer.  
Enhanced Other Network  
Stations that offer <Enhanced Other  
Network> also transmit information about  
other RDS stations that have traffic  
information. When you are tuned to a station  
that is not transmitting traffic information, but  
another RDS station starts transmitting a  
traffic bulletin, the tuner automatically  
switches to the other station for the duration  
of the bulletin.  
Alarm  
When an emergency transmission (announcing  
disasters, etc.) is sent, all current functions are  
interrupted to allow the warning to be  
received.

• 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.  
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 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.  
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.  
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 left part at the upper side of the faceplate once to  
make the faceplate control panel appear.
