[. . . ] 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. Set the unit according to the intended usage. Connect the input and output cables of the units. 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. 4½ 4½ 4½ 4½ FCC WARNING This equipment may generate or use radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made. s 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. 2CAUTION 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. 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. Otherwise heat build-up occurs and the unit may be damaged. · Install this unit in a location which allows heat to easily dissipate. Once installed, do not place any object on top of the unit. [. . . ] · After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally.
