Thanks Ericjb.

I'm on ID 0, and all appears clear on the STATUS lite.

I am not receiving any IR out of the ports - I've verified this.

I have fully reset the unit to defaults (by pressing and holding MENU button for 5+ seconds and doing factory reset) then download program.

I have to make a correction: RF doesn't work with USB/Emulator as I thought.

What I did was order another MRF-250 because I think it has been progressively dying - because the problem has been getting worse over past 3 months. Usually full resets and re-download of application.
