|If the second receiver is ON (steady or blinking green LED), power on then |off results in the sub rcvr being on (green light steady). That's |how my MP |works. This is how mine works (muted flashing green) as well however I would have bet a coffee that my previous MP model stayed in the muted mode :-) May just be the way I interact with the new location of the 2nd receiver volume control. Tnx Paul
