2CAUTION

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 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 place the faceplate (and 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, as it is a piece of precision equipment. When replacing a fuse, only use a new fuse 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. Use only the screws provided or specified for installation. If you use wrong screws, you could damage the unit.

You can damage both your unit and the CD changer if you connect them incorrectly.

Lens Fogging

When you turn on the car heater in cold weather, dew or condensation may form on the lens in the CD player of the unit. Called lens fogging, this condensation on the lens may not allow CDs to play. In such 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.

Accessories/ Installation Procedure
Accessories 1..1 2..2 3..4 4..4 5..2 6..1 7..1
If the power is not turned ON ("PROTECT" is displayed), the speaker wire may have a short-circuit or touched the chassis of the vehicle and the protection function may have been activated. Therefore, the speaker wire should be checked. If your cars 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 arent 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. After the unit is installed, check whether the brake lamps, blinkers, wipers, etc. on the car are working properly. Mount the unit so that the mounting angle is 30 or less.
