I've got an old M5100-EX that has lived it's life with a 12v trigger from an AC-3 plugged into the back. I've disconnected most of the old equipment, including the AC-3. With the 12v trigger unplugged from the back of the Panamax unit, banks 2 and 3 shut off, and Ican't get banks 2 and 3 to turn back on. The user manual says:
Power Button
Press and hold for 2 seconds to turn Bank 2 and
Bank 3 outlets ON or OFF.
This switch is bypassed if
the rear panel DC Trigger
input is being used.
Am I missing something obvious here? The power button isn't turning them on, even with the trigger cable removed.
