CAUTION
Never replace the fuse with one of greater value or rating than the original fuse. Use of an improper fuse could result in overheating and smoke and could cause damage to the product and injury including burns.

WARNING
� Handling the cord on this product or cords associated with accessories sold with the product will expose you to lead, a chemical known to the State of California and other governmental entities to cause cancer and birth defects or other reproductive harm. Wash hands after handling. � Always use the special red battery and ground wire [RD-223], which is sold separately. Connect the battery wire directly to the car battery positive terminal (+) and the ground wire to the car body. � Do not touch the amplifier with wet hands. Otherwise you may get an electric shock. Also, do not touch the amplifier when it is wet. � For traffic safety and to maintain safe driving conditions, keep the volume low enough so that you can still hear normal traffic sound. � Check the connections of the power supply and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. Detect the cause and solve the problem, then replace the fuse with another one of the same size and rating. � To prevent malfunction of the amplifier and speakers, the protective circuit will cut the power supply to the amplifier (sound will stop) when an abnormal condition occurs. In such a case, switch the power to the system OFF and check the connection of the power supply and speakers. Detect the cause and solve the problem. Contact the dealer if you cannot detect the cause. To prevent an electric shock or short-circuit during connection and installation, be sure to disconnect the negative (�) terminal of the battery beforehand. Confirm that no parts are behind the panel when drilling a hole for installation of the amplifier. Be sure to protect all cables and important equipment such as fuel lines, brake lines and the electrical wiring from damage. DO NOT allow amplifier to come into contact with liquids due to, for example, the location where the amplifier is installed. Electrical shock could result. Also, amplifier and speaker damage, smoke, and overheating could result from contact with liquids. In addition, the amplifier surface and the surface of any attached speakers could become hot to the touch and minor burns could result.

Do NOT install or use your Pioneer amplifier by wiring speakers rated at 4 � (or lower) in parallel to achieve a 2 � (or lower) bridged mode (Diagram B). Amplifier damage, smoke, and overheating could result from improper bridging. The amplifier surface could also become hot to the touch and minor burns could result. To properly install or use a bridged mode for a two-channel amplifier and achieve a 4 � load, wire two 8 � speakers in parallel with Left + and Right � (Diagram A) or use a single 4 � speaker. For a four-channel amplifier, follow the speaker output connection diagram for bridging as shown on the back of your amplifier, and wire two 8 � speakers in parallel to achieve a 4 � load or use a single 4 � speaker per channel. If you have any questions or concerns, please contact your local authorized Pioneer dealer or call Pioneer customer service.
