I don't mean to be rude, since you are obviously going through some effort to find answers to our questions, but don't you have the specifications for all this stuff? Not the set you put on the box, but the set your engineers (whether in house or outsourced) worked from?

It doesn't bode well that you have to set up tests to answer the question. You guys designed this thing, but don't know how it works?

This goes for the discreet remote codes, as well.

Again, sorry to sound harsh. I don't want to hurt any feelings, but I also don't want to spend a good chunk of money on something with a feature set that the manufacturer doesn't have a handle on.
