with out human action.. It sends a volume blasting up or
changes the channel... What do
you think it could be....No gost replies please.....
Just a thought - I know you said no human action, but is this perchance happening immediately AFTER they have pressed the volume up command? The Harmony's are buggers for delaying and sustaining repeat commands (such as volume up), and can continue for several seconds after the button in question is released.
