Information on Disposal of Old Electrical and Electronic Equipment (applicable for countries that have adopted separate waste collection systems)

Products with the symbol (crossed-out wheeled bin) cannot be disposed as household waste. Old electrical and electronic equipment should be recycled at a facility capable of handling these items and their waste byproducts. Contact your local authority for details in locating a recycle facility nearest to you. Proper recycling and waste disposal will help conserve resources whilst preventing detrimental effects on our health and the environment.

This Product is not installed by the manufacturer of a vehicle on the production line, nor by the professional importer of a vehicle into an EU Member State.

Information sur l’élimination des anciens équipements électriques et électroniques (applicable dans les pays qui ont adopté des systèmes de collecte sélective)

Les produits sur lesquels le pictogramme (poubelle barrée) est apposé ne peuvent pas être éliminés comme ordures ménagères. Les anciens équipements électriques et électroniques doivent être recyclés sur des sites capables de traiter ces produits et leurs déchets. Contactez vos autorités locales pour connaître le site de recyclage le plus proche. Un recyclage adapté et l’élimination des déchets aideront à conserver les ressources et à nous préserver des leurs effets nocifs sur notre santé et sur l’environnement.

Ce produit n’est pas installé par le constructeur d’un véhicule sur le site de production, ni par l’importateur professionnel d’un véhicule dans un Etat membre de l’UE.

Información acerca de la eliminación de equipos eléctricos y electrónicos al final de la vida útil (aplicable a los países que hayan adoptado sistemas independientes de recogida de residuos)

Los productos con el símbolo de un contenedor con ruedas tachado no podrán ser desechados como residuos domésticos. Los equipos eléctricos y electrónicos al final de la vida útil, deberán ser reciclados en instalaciones que puedan dar el tratamiento adecuado a estos productos y a sus subproductos residuales correspondientes. Póngase en contacto con su administración local para obtener información sobre el punto de recogida más cercano. Un tratamiento correcto del reciclaje y la eliminación de residuos ayuda a conservar los recursos y evita al mismo

tiempo efectos perjudiciales en la salud y el medio ambiente. Este producto no ha sido instalado en la línea de producción por el fabricante de un vehículo, ni tampoco por el

importador profesional de un vehículo dentro del estado miembro de la UE.

Safety precautions

WARNING

To prevent injury or fire, take the following precautions:

• Mounting and wiring this product requires skills and experience. For safety’s sake, leave the mounting and wiring work to professionals.

• To prevent a short circuit, never put or leave any metallic objects (such as 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.

• Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched.

CAUTION

To prevent damage to the machine, take the following precautions:

• Be sure the unit is connected to a 12V DC power supply with a negative ground connection.

• 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.

• 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 a short circuit when replacing a fuse, first disconnect the wiring harness.

NOTE

• If you experience problems during installation, consult your Kenwood dealer.

• If the unit does not seem to be working right, consult your Kenwood dealer.

Cleaning the unit

If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth.

CAUTION

Do not wipe the panel with a hard cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and/or cause the indicator letters to peel off.

To prevent battery rise

When the unit is used in the ACC ON position without turning the engine ON, it depletes the battery. Use it after starting the engine.

Protection function

The protection function is activated in the following situations: This unit is equipped with a protection function for protecting this unit and your speakers from various accidents or problems that can occur. When the protection function is triggered, the amplifier stops operating.

• When a speaker wire may be short-circuited.

• When a speaker output contacts ground.

• When the unit malfunctions and a DC signal is sent to the speaker output.

• When the internal temperature is high and unit won’t operate.

• When detects a low impedance at the speaker connections.

7 Wiring

• If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery wire.

• Do not allow the wire to directly contact the edge of the iron plate by using Grommets.

• Connect the ground wire to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery‘s negative · terminal. Do not turn the power on if the ground wire is not connected.

• Be sure to install a protective fuse in the power cord near the battery. The protective fuse should be the same capacity as the unit’s fuse capacity or somewhat larger.

• When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier.

7 Speaker selection

• Using speakers with smaller input ratings than the amplifier’s output power would result in smoke generation or equipment failure.

• Use speakers that have an impedance of 4Ω or greater. When more than one set of speakers are going to be used, calculate the combined impedance of the speakers and then connect suitable speakers to the amplifier.
