Troubleshooting Guide

What 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 following table for possible problems.

PROBLEM	POSSIBLE CAUSE		SOLUTION
No sound.	•	Input (or output) cables are disconnected.	• Connect the input (or output) cables.
(Blown fuse.)	•	Protection circuit may be activated.	• Check connections by referring to <Protection function>.
	• Volume is too high.		• Replace the fuse and use lower volume.
	• The speaker cord is shorted.		• After check the speaker cord and fixing the cause of the short,
			replace the fuse.
The output level is too small	•	The input sensitivity adjusting control is not set to the correct	• Adjust the control correctly referring to <Controls>.
(or too large).		position.
The sound quality is bad.	• The speakers wire are connected with wrong + /-polarity.		• Connect them properly checking the + / - of the terminals
(The sound is distorted.)			and wires well.
	• A speaker wire is pinched by a screw in the car body.		• Connect the speaker wire again so that it is not pinched by
			anything.
	• The switches may be set improperly.		• Set switches properly by referring to <Controls>.
