I just got my 810 yesterday, spent ~4 hours programming, but it would not turn ON/OFF my ARCAM AVR300. I tried learning commands from original remote, but then realized that I can get codes for ARCAM from it's manual.

Q: how do I assign a descrete code ( a number like 124)to a button on MX810 ?

Thank you very much.
