About the protector indicator

The amplier has a built-in protection circuit to

protect the transistors and speakers when:

The unit is overheated. Or•
A DC current is generated. Or•
The batter y voltage is over low or •
over high. Or

The speaker terminals are shor t •
circuited.
When the PROTECT indicator
lights up in red, the unit shuts down
automatically. If this happens, please:

1 Take out the disc or tape and turn off the

car audio.

2 Check the cause of the malfunction (see

above).

3 If the amplier has overheated, wait until

the unit cools down before use.

Replace fuse

If there is no power, the fuse may be damaged
and need to be replaced.

1 Pull out the damaged fuse.
2 Replace the fuse with the supplied fuses

or to buy two fuses that matches the
voltage of the damaged fuse (20A x 2).

English

If the fuse gets damaged immediately after it
has been replaced, there may be an internal
malfunction. In such case, consult your Philips
dealer.
