and negative speaker connection wires are “shorted”, or if speaker systems with an
impedance less than the indicated rated impedance of the amplifier are used.
If this occurs, follow the procedure outlines below:

1. Turn off the power.

2. Determine the cause of the problem and correct it.

3. Turn on the power once again after one minute.

Note:
When the protection circuitry functions, the unit will not operate unless the power is
first turned off and then on again.
