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.

(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 correct

position.

• Adjust the control correctly referring to <Input Sensitivity>.

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.

• The “OVER” indicator is lit.

• 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> or <DSP

Settings>.

• Input level is too high. See <Input Sensitivity> and adjust.
