What can I do when the protector indicator lights up in red?


The amplifier has a build-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 protector indicator lights up in red, the amplifier shuts down automatically. In this case please:

  • Take out the disc or tape and turn off the car audio.
  • Check the cause of the malfunction.
  • If the amplifier is overheated, let it cool down.
