Safety precautions  
2WARNING  
2CAUTION  
To prevent injury and/or fire, take the  
following precautions:  
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.  
• 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 a 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.  
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.  
• 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 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  
Cleaning the Faceplate Terminals  
If the terminals on the unit or faceplate get  
dirty, wipe them with a dry, soft cloth.  
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.  
NOTE  
• 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.  
Cleaning the Unit  
About Cassette tape  
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.  
• 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.  
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.  
• 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.  
Reset button  
• 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.

• 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 reset button.
