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.
PROBLEM POSSIBLE CAUSE SOLUTION
No sound.
(No sound from one side.)
The output level is too
small (or too large).
The sound quality is bad.
(The sound is distorted.)
• Input (or output) cables are
disconnected.
• The connection of the sigma
servo terminals is wrong.
• Protection circuit may be
activated.
• The fuse may be blown
because the volume was too
high.
The input sensitivity adjusting
control is not set to the correct
position.
• The speakers cable are
connected with wrong + / -
polarity.
• A speaker cable is pinched by a
screw in the car body.
• The switches may be set
improperly.
• Connect the input (or output)
cables.
• Check the connection referring
to "Sigma servo feed back".
• Check connections by referring
to "Power indicator".
• Replace the fuse with a new
fuse and use a lower volume.
Adjust the control correctly
referring to "Controls".
• Connect them properly checking
the + / - of the terminals and
cables well.
• Connect the speaker cable again
so that it is not pinched by
anything.
• Set switches properly by
