The red reset switch on the right is included in case the unit experiences power dis-
turbances or incorrect shutdown (i.e. pulling the plug) and enters protection mode.
This mode causes the unit to stay in bypass and remain unpowered until someone
opens the door and briefly pushes the reset switch. This prevents brown- or black-
outs from causing audio interruptions and/or permanently damaging the unit.
To date, this feature has saved several units from complete destruction during bad
weather storms.
