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.

No sound. (Blown fuse.)

Input (or output) cables are disconnected.

Connect the input (or output) cables.

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 (or too large).

The input sensitivity adjusting control is not set to the correct position. Adjust the control correctly referring to <Controls>.

The sound quality is bad. (The sound is distorted.)

The speakers wire are connected with wrong 9 / · polarity.

Connect them properly checking the 9 / · of the terminals 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>.

1Power indicator

When the power is turned on, the Power indicator lights.

If the Power indicator does not light when the power is turned on, the protection function may be activated. Check whether there is any indication of trouble. Refer to <Protection function> (page 3).

2Illumination

3ISF (infrasonic filter) switch

Ultralow frequencies that cannot be reproduced even by a subwoofer speaker do not become sound but become unnecessary oscillations, which affect the sound by causing distortion, etc. Setting this switch to "15 Hz" or "25 Hz" cuts the frequencies below the respective frequency.

This improves the reproduction performance of the speakers by eliminating unnecessary oscillations which will not become sound.

4PHASE switch

When this switch is set "180°" (Reverse) the speaker output phase is reversed.

5BASS BOOST LEVEL control

Sets the low frequency level to be compensated.

6LPF(Low-Pass Filter) FREQUENCY control

This control adjusts the frequency band output from this unit.

7INPUT SENSITIVITY control

Set this control according to the pre-output level of the center unit connected with this unit, or to the maximum power output of the genuine-accessory car stereo.

Use the diagram on the right as a guide.
