English 9Troubleshooting GuideWhat might appear to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before calling service, first check the followingtable for possible problems.PROBLEM POSSIBLE CAUSE SOLUTIONNo sound.(No sound from one side.)(Blown fuse.)• Input (or output) cables are disconnected.• Protection circuit may be activated.• Volume is too high.• The speaker cord is shorted.• Connect the input (or output) cables.• Check connections by referring to "Protection function".• Replace the fuse and use lower volume.• After check the speaker cord and fixing the cause of the short,replace the fuse.The output level is too small(or too large).• The input sensitivity adjusting control is not set to the correctposition.• Adjust the control correctly referring to "Controls".The sound quality is bad.(The sound is distorted.)• 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.• Connect them properly checking the + / - of the terminalsand wires well.• Connect the speaker wire again so that it is not pinched byanything.• Set switches properly by referring to "System examples".The sound does not changeeven when you have changedit with the Amplifier Control.• The AMP CONT has been turned "OFF".• The filtered band has been controlled by the Amplifier Control.• Turn the AMP CONT "ON".• Turn the filter Off.The set value cannot bechanged by the AmplifierControl of the unit.• The AMP Control of the Center Unit is being used. • Release the AMP Control mode of the Center Unit.The Amplifier Control cannotbe operated from the CenterUnit.• An incorrect ID number is used for the Master amplifier.• The ID number of the amplifier has been changed.• Always set the ID number of the Master amplifier to "0".• After you have changed the ID number of an amplifier, turn Offthe POWER switch of the Center Unit first, then turn it On again.SpecificationsSpecifications subject to change without notice.Audio
