Where I work we have a Bose Lifestyle 28 and a 3-2-1 running Bose-made demo videos. The thing is I am fed up with hearing the same repetative (boring as hell, too) demos that company supplies to play in these systems. Both systems are set up in permenant fixtures and their manuals were put away by our in store Bose rep (which I don't want finding out I'm doing this) which is hardly ever there. Also, whenever someone feels the need to press the pretty red flashing button to play the demos the speakers come on blasting people away while they cover their ears. I just want to turn those darn demos OFF. Anyone here know how?
