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.
SOLUTION POSSIBLE CAUSE PROBLEM
The tape head is dirty. Clean the tape head, referring to the section on "Cleaning
the tape head" (see page 4).
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 experi-
enced, the first tape was bad.
Nothing happens when the but-
tons are pressed. The computer chip in the unit is not functioning normally. Press the reset button on the unit (see page 4).
The sound quality is poor or dis-
torted.
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 antenna control cable is not connected. Connect the cable correctly, referring to the section on
"Connecting Cables to Terminals".
Radio reception is poor. The car antenna is not extended. Pull out the antenna all the way.
The power does not turn on. The fuse has blown. After checking for short circuits in the cables, replace the
fuse with one having the same rating.
The Attenuator function is turned on. Turn off the Attenuator function.
Troubleshooting Guide
No ACC position on vehicle ignition. Connect the same cable to the ignition as the battery cable.
