Do Not Load 8-cm (3-in.) CDs in the CD slot
If you try to load an 8-cm CD with its adapter into the unit, the adapter might separate from the CD and damage the unit.

Handling Compact discs

Playing a CD that is dirty, scratched or warped can cause the sound to skip and the unit to operate incorrectly, resulting in worsened sound quality. Take the following precautions to prevent your CDs from getting scratched or damaged. Handling CDs
Do not touch the recorded side of the CD (i.e., the side opposite the label) when holding it.

Cleaning CDs

If a CD has become dirty, wipe it off gently using a commercially available cleaning cloth or a soft cotton cloth, starting from the centre of the disc and moving outward. Do not clean CDs with conventional record cleaners, anti- static formulas, or chemicals such as paint thinner or benzene.
Do Not Load CD Accessories in Slot
Do not use commercially available CD accessories that can be loaded into the CD slot, such as stabilisers, protective sheets, or CD cleaning discs, since they can cause the unit to malfunction.

Removing the CD

Only remove the CD from the machine in a horizontal direction. You may damage the surface of the CD if you try pulling it down as it ejects.
Checking New CDs for Burrs
When playing a new CD for the first time, check that there are not any burrs stuck to the perimeter of the disc or in the central hole. CDs with burrs stuck on them may not load properly or may skip whilst playing. Remove burrs using a ballpoint pen or a similar utensil.
Do Not Use Special Shape CDs
Be sure to use round shape CDs only for this unit and do not use any special shape CDs. Use of special shape CDs may cause the unit to malfunction.
Do not stick tape on either side of the CD.

Storing CDs

Do not store CDs in areas exposed to direct sunlight such as a car seat or above the fascia panel (dashboard) or other hot places. Remove CDs from the unit when not listening to them for a whilst, and put them back in their cases. Do not stack CDs that have been removed from their cases or prop them against something.

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

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 cable connections for each unit. 3. Connect the cable 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.

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 cable 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 cable is connected to a power source with constant voltage such as a battery cable, 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 cable to a power source that can be turned on and off with the ignition key. If the fuse blows, first make sure that the cables have not caused a short circuit, then replace the old fuse with one with the same rating. Do not let unconnected cables or terminals touch metal on the car or anything else conducting electricity. To prevent short circuits, also do not remove the caps on the ends of the unconnected cables or the terminals. Connect the speaker cables correctly to the terminals to which they correspond. The unit may receive damage or fail to work if you share the - cables 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. Insulate unconnected cables with vinyl tape or other similar material. Some disc changers need conversion cables for connection. See the section on "Safety Precautions" for details. 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.
