OK, think I got mute to work fine with RS232 and MSC-400. I unchecked (repeat while button is pressed). Still Volume is double executed, 2 db at a time- not that big of a deal but wondering if anyone has fixed the double commands as stated above when the box is checked. There may be other situations I will come across that I am not thinking about right now. Thanks.
Sometimes you just have to figure it out for yourself!
