I sent the following Email to Universal Remote service:
"I currently have a MX-700 and a new MX-850.
I was using the MX-850 to try and “learn” the Velodyne DD series Subwoofer remote codes. The 850 would not ‘learn’ any of the codes except the ON/OFF toggle. I tried this at various nose-to-nose distances.
I decided to try it with my MX-700 and it ‘learned’ every code correctly. I used that 700 file and loaded it into the 850 and it functioned correctly with the 850.
I did try using one of my other remotes and have the 850 ‘learn’ its codes and the 850 functioned correctly. ???
Is there a defective problem with the MX-850, or will the MX-700 read some codes while the 850 will not? Remember that the 850 did read the Velodyne ON/OFF toggle code.
