Glen, I am unaware of the backup memory system you spoke of but resetting them after losing the settings is a 3 minute deal. Feel free to call myself or any number of folks on the list probably before you kill the DC and I for one will be glad to walk you through the menu and let you record any pertinent settings that apply to that system. Thanks, Nathan Jones Power Source Solar Inc. 417-827-0738
