Before calling service, first check the following table for possible problems. PROBLEM No sound. (No sound from one side.) (Blown fuse.) POSSIBLE CAUSE • Input (or output) cables are disconnected. • Protection circuit may be activated. • Volume is too high. • The speaker cord is shorted. SOLUTION • Connect the input (or output) cables. • Check connections by referring to "Power indicator". • Replace the fuse and use lower volume. • After check the speaker cord and fixing the cause of the short, replace the fuse. Adjust the control correctly referring to "Controls". • Connect them properly checking the + / - of the terminals and wires well. • Connect the speaker wire again so that it is not pinched by anything. • Set switches properly by referring to "System examples". KAC-849 KAC-749S 4-CHANNEL POWER AMPLIFIER The output level is too small (or too large). The sound quality is bad. (The sound is distorted.) The input sensitivity adjusting control is not set to the correct position. • The speakers wire are connected with wrong + / polarity. • A speaker wire is pinched by a screw in the car body. • The switches may be set improperly.

Do not turn the power on if the ground wire is not connected. • Be sure to attach a protective fuse into the battery wire close to the battery. Use a protective fuse having a capacity that is about 10 A higher .
