Troubleshooting Guide
SOLUTION POSSIBLE CAUSE PROBLEM
The tape head is dirty. Clean the tape head, referring to the section on
"Cleaning the tape head" (see page 5).
No sound can be heard, or the
volume is low.
The fader and/or balance settings are set all the way to
one side. Reset the fader and/or balance settings.
The input/output cables or wiring harness are connected
incorrectly. Reconnect the input/output cables and/or the wiring
harness correctly. See the section on "Connecting
Cables to Terminals".
The cassette tape is bad. Try playing another cassette tape. If no problem is
experienced, the first tape was bad.
The sound quality is poor or
distorted.
The speakers are not wired correctly. Reconnect the speaker cables so that each output
terminal is connected to a different speaker.
A speaker cable may be pinched by a screw in the car. Check the speaker wiring.
The Attenuator function is turned on. Turn off the Attenuator function.
The tape does not go in. /
No sound can be heard even
though the tape display is made. The car ignition was turned off during tape eject; or the
tape was pulled out during loading, switching the mode
to tape mode even though no tape is in. Press the Eject button.
The values of Volume offset are low. Increase the values of Volume offset. (see p. 13)
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.
