Model KA-3500 Serial number © PRINTED IN USA B64-1980-00 (KM/EM) Safety precautions 2WARNING s 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. [. . . ] Use a protective fuse having a capacity that is about 10 A higher than the maximum current drawn by the amplifier. · Use vehicle-type (fire-resistant) power supply wiring wire for the battery wire and the ground wire. The current capacity of the power supply wiring wire should be about 10 A higher than that of the protective fuse capacity (which means about 20 A higher than the maximum current drawn by the amplifier). · 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. Installation procedure 1. Remove the ignition key and disconnect the negative - terminal of the battery to prevent short circuits. Connect the power wire, power control wire and grounding wire following this order. Connect the negative - terminal of the battery. 2WARNING s Power terminal (234) Connect to their respective terminals the power supply wire, and ground wire, all of which pass through the associated terminal cover. Once the connections are complete, place the cover on the terminal section. To prevent injury or fire, take the following precautions: · When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 5mm2 (AWG10) 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. 2CAUTION s Accessories Part name Terminal cover (Power terminal) Self-tapping screws (ø4 ´ 16 mm) External View Number of Items 1 4 To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery's positive terminal. 2CAUTION Installation Since the power amplifier has no parts which require operation, it can be installed at a position away from the driver's seat without any hindrances. They can scratch the surface of the panel and/or cause the indicator letters to peel off. 8½ 2½ · The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. · Do not connect the speaker output leads from a power amplifier (Optional) to the speaker level input terminals of this unit, for this may cause malfunction or damage. · Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage. · Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line). With this connection, shock noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF. · Do not install the unit under the carpet. · Install this unit in a location which allows heat to easily dissipate. · The surface temperature of the amplifier will become hot during use. Install the amplifier in a place where people, resins, and other substances that are sensitive to heat will not come into contact with it. · When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or wiring harness, and be careful not to cause scratches or other damage. · Do not install near the dashboard, rear tray, or air bag safety parts. · The installation to the vehicle should securely fasten the unit to a place in which it will not obstruct driving. [. . . ] · The installation to the vehicle should securely fasten the unit to a place in which it will not obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may cause injury or an accident. · After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally.
