Thank you for the fuse suggestion and the longer unplugging suggestion. The fuse is O.K., so, I'm leaving it unplugged for a couple of days before contacting Outlaw. The L.E.D. under the famous green button continues to burn brightly while the unit is plugged in but the button itself feels like it doesn't want to depress, as if it is stuck in the depressed position. I don't want to push it beyond a firm push for fear of breaking something but maybe the problem is within the mechanical action of the switch connected to the button! Does anyone have any further thoughts before I give up and begin boxing it up for shipping? The thought of sending it back stirs up feelings of depression. I guess I'm trying to avoid parting with it.
