I've tried using all the codes supplied by Cisco for the remote/receiver combination and I've tried using "auto-searching the code library" function built into the remote with no result.

Using a couple of the codes published in the AT6400 manual I can use the remote to change volume on the receiver, and to turn the receiver off, but NONE of the codes will let me turn the receiver ON with the AT6400.

The auto-search function finds 6 or 7 codes that turn the reliever off, two that start the sleep timer function, but none that will turn the receiver ON.

Is there a setting in the Yamaha that I'm missing, or will this remote to work with this receiver?

Thanks for the help, and happy new year!
