Troubleshooting Guide

If the following situations, consult your nearest service center:

• Even though the disc changer is connected, the Disc Changer Mode is not on, with "AVin" showing in the display during the Changer

Mode.

• Even though no device (

KCA-S210A, CA-C1AX, KDC-CPS87, KDC-CX87, KDC-CPS85, KDC-CX85, KDC-CPS82 or KDC-CX82

) is connected, the AUX

Mode is entered when switching modes.

SOLUTION

POSSIBLE CAUSE

PROBLEM

Free switching of the sound
quality.

The system Q function is set on Scan mode.

Refer to the “System Q” page and switch it to a
function other than Scan mode.(see p. 6).

Can’t remove tape.

The cause is that more than 10 minutes has elapsed
since the vehicle ACC switch was turned OFF.

The tape can only be removed within 10 minutes of the
ACC switch being turned OFF. If more than 10 minutes
has elapsed, turn the ACC switch ON again and press
the Eject button.
