For New Zealand Customers The benefits of the express warranty described below are in addition to your statutory rights and remedies under the Consumer Guarantees Act 1993 that cannot be excluded. If you are acquiring Product for the purposes of a business, to the extent permitted by law, the Consumer Guarantees Act 1993 does not apply. Otherwise nothing in this warranty is to be interpreted as excluding, or restricting, the Consumer Guarantees Act 1993. To the extent permitted by law, all other warranties, guarantees or representations (whether implied by statute, common law or custom of the trade or otherwise) in respect of the Product, not expressly included in this warranty, are excluded. 3. 4. 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. • When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with the range of 5 mm2 (AWG 10) or more to prevent wire deterioration and damage to the wire coating. • 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. 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. <Example> 防止蓄电池全部放电 当本机在ACC ON位置使用而不开动发动机时，将消耗蓄电池 的电量。 请在开动了发动机之后使用。 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. 保护功能 在以下场合中保护功能被激活 本机装有保护功能，可以保护本机以及扬声器不会受到可能 发生的各种意外事故的损害。 当保护功能被触发时，电源指示灯将熄灭，放大器也停止工 作。 • 当扬声器缆线短路时。 • 当扬声器的输出接地时。 • 当本机出现误动作，有 DC（直流） 信号传送到扬声器输出 端时。 • 内部高温不能动作时。 9. 2. The warranty does not extend to: 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.

Remove the ignition key and disconnect the negative · terminal of the battery to prevent short circuits. Set the unit according to the intended usage. Connect the input and output wires of the units. Connect the power wire, power control wire and grounding wire following this order. Install the installation fittings in the unit. [. . . ] Sharing the negative wire of the speaker or grounding speaker wires to the metal body of the car can cause this unit to fail. • After installation, check that the brake lamps, turn signal lamps and windshield wipers work properly. 警告 要特别注意放大器的输出口和扬声器端子处有良好的电气 接触。 因为放大器要发出非常高的功率，松弛或不良的连接可能 在端子处产生火花甚至燃烧。 注意 ・ 如果声音输出不正常，应立即关断电源并检查连接是否正 确。 ・ 在变更开关的设定时，必须首先切断电源。 ・ 当保险丝熔断后，要检查缆线是否有短路，并更换上相同 规格的保险丝。 ・ 检查是否有尚未连接的缆线或与车体相接触的端头。 未 连接缆线及其端部的保护帽不可拆掉，以防短路。 ・ 扬声器的缆线要分别连接到各自的端子。 共用扬声器的 负极缆线或将扬声器端子接地到汽车的金属部分，都会导 致本机停止工作。 ・ 安装之后，请检查汽车的刹车灯、方向指示灯、雨刷等是 否正常动作。 保护保险丝 Lead terminal 引出端子 192 mm 127 mm Stereo / 立体声 A. ch Left 左 Battery wire 蓄电池导线 A. ch Right 右 B. ch Left Protective fuse 左 B. ch Right 右 WARNING To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s positive terminal. 警告 为了防止短路所引起的火灾，在蓄电池的正极附近 连接保险丝或断电器。 Bridged / 桥接 Battery 蓄电池 Ground wire 接地导线 A. ch B. ch Connection / 连接 7 RCA cable connections 7 连接RCA 缆线 Center unit (CD receiver, etc. ) 中心装置（CD 接收机等） System examples / 系统配置实例 ■ 4-channel system ■ 4 声道系统 Center unit 中心装置 L L A R R L L B R R Controls / 控制 Front left speaker 前置左扬声器 Front right speaker 前置右扬声器 Rear left speaker 后置左扬声器 Rear right speaker 后置右扬声器 Power control wire 电源控制缆线 RCA cable RCA 缆线 ■ High-power 2-channel system ■ 大功率 2 声道系统 L 1 L L A R R L L B R R Center unit 中心装置 Left speaker (Bridged) 左扬声器 (桥接) Right speaker (Bridged) 右扬声器 (桥接) 2 3 4 8 5 0 6 R A. ch B. ch ■ 2-channel + Subwoofer system ■ 2 声道 + 副低音扬声器系统 7 Speaker level input connections 7 连接扬声器电平输入 Center unit 中心装置 L L A R R L L B R R Left speaker (high pass) 左扬声器 (高通滤波器) Right speaker (high pass) 右扬声器 (高通滤波器) Subwoofer (Bridged) 副低音扬声器 (桥接) 7 This is a 4 channel amplifier including 2 stereo amplifiers in a body.
