POSSIBLE CAUSE
• Input (or output) cables are disconnected.
• Protection circuit may be activated.
• Volume is too high.
• The speaker cord is shorted.
• 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.
• The Remote Cable is disconnected.
• The "BOOST LEVEL" is set to "0dB".

SOLUTION
• 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.
• 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 <Controls>.
• Connect the Remote Cable securely and correctly.
• Adjust the "BOOST LEVEL".
