Before use

2WARNING
To prevent injury or fire, take the following precautions:
To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit. If you experience problems during installation, consult your Kenwood dealer. When you purchase optional accessories, check with your Kenwood dealer to make sure that they work with your model and in your area. The characters which can be displayed by this unit are A-Z 0-9 @ " ` % & * + = ,. / \ < > [ ] ( ) : ; ^ - { } | ~. (KDC-MP439/KDC-MP3039/KDC-MP339/KDCMP239) 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 be inapplicable.

SPRM (Supreme) Technology to extrapolate and supplement with proprietary algorithm, the high-frequency range that is cut off when encoding at low bit rate. Supplementing is optimized by compression format (MP3 or WMA) and processed according to bit rate. The effect is negligible with music that is encoded at high bit rate, variable bit rate or has minimal high frequency range. CD READ Sets the method for reading CD. When unable to play special format CD, set this function to 2 to force playing. Note that some music CD may be unplayable even when set to 2. In addition, audio files cannot be played when set to 2.

Accessories/ Installation Procedure
Accessories 1..1 2..2 3..4 4..4 Installation Procedure
1. To prevent a short circuit, remove the key from the ignition and disconnect the - battery. 2. Make the proper input and output wire connections for each unit. 3. Connect the speaker wires of the wiring harness. 4. Connect the wiring harness wires in the following order: ground, battery, ignition. 5. Connect the wiring harness connector to the unit. 6. Install the unit in your car. 7. Reconnect the - battery. 8. Press the reset button.
If you use the wrong screws, you could damage the unit. If the power is not turned ON (PROTECT/DCER 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.

About CD players/disc changers connected to this unit
Kenwood disc changers/ CD players released in 1998 or later can be connected to this unit. Refer to the catalog or consult your Kenwood dealer for connectable models of disc changers/ CD players.

Connecting unsupported disc changers/CD players to this unit may result in damage. Set the O-N Switch to the N position for the applicable Kenwood disc changers/ CD players. The functions you can use and the information that can be displayed may differ depending on the models being connected.
If you connect the ignition wire (red) and the battery wire (yellow) to the car chassis (ground), you may cause a short circuit, that in turn may start a fire. Always connect those wires to the power source running through the fuse box.
Mounting and wiring this product requires skills and experience. For safetys sake, leave the mounting and wiring work to professionals. 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 use your own screws. Use only the screws provided.
