About the protector

indicator

The ampliﬁer has a built-in protection circuit to

protect the transistors and speakers in following

conditions:

The ampliﬁer is overheated.•

A DC current is generated in•

speakers.

The battery voltage is too low or too•

high. Or

The speaker terminals are short•

circuited.

When the PROTECTED indicator

lights up in red, the ampliﬁer shuts

down automatically. In this case

please:

1Take out the disc or tape and turn off the

car audio.

2Check the cause of the malfunction.

3If the ampliﬁer is overheated, let it cool

down.

4 Use your power
