The button over the power socket on the back of the unit? My old preamp had this. I believe it tests the phase of the electrical from the wall. I think it lights up when in the correct phase. I can't remember but I did read this somewhere online and not from the manual. Call On A Higher Note (the importer). They'll help you out.
