Ok - I have had a pair of Odysseys for a year now... and the other day I stuck my head between the stat & woofer assembly (that is legal in Michigan)... and see this little red button below the ML logo. I assume it is to dim or shut off the logo... but I don't want to press it in fear of launching some missiles out of a silo in Kansas. Can anyone verify it is nowhere in the documentation. BTW, vacuumed my Odysseys for the first time - (I didn't see any dust...but what the heck) and replaced a crappy plug my amp & stat were plugged into. More solid sound now. I'm not sure if it is the vacuum or the replaced plug. Maybe I'm crazy. Thx. Tim.
