  Supply Low - is detected if the output is less than 90% of nominal, due to supply restriction. Open Circuit - Faults do not affect operation - The offending output is driven regardless. Short Circuit - Faults disable only the offending speaker output, the other speaker output functions normally - this may be cleared by cycling the power or warning tone input.   Faults detected during operation are latched and displayed on the LED until the power is cycled or the ON input rises.
