No problem!

I grinned a bit this morning when thinking about this particular situation. I also don't have headphones in my system, but one day probably late last year I had the equipment rack door and our toddler grabbed the volume knob rather suddenly. My reflex was to hit mute, but she of course released the mute by turning the knob. Without thinking, I simply held the mute button down - and by the time the volume knob was safe the 990 had gone to headphone mode. It took me a moment to realize what had happened when I tried to un-mute the 990...
