This warning was valid fifteen years ago but it might still be so: If you use a Yamaha codeset for a different product, prepare to be surprised by the surround commands and perhaps the input commands.

Way back when, Yamaha used the same remote control physical button layout on more than one product's remote, but the input and surround commands were not always on the same buttons from one model's remote to another.

This meant that, say, the top left input button might be CD on one remote and DVD on another. And if you opened up the file for that second receiver to retrieve a CD command (top left button), you'd get the DVD command (top left button). This was more obvious with the extended set of DSP commands. There would be blank commands and wrong commands when you looked up the wrong model. The commands were all there, just not in the right place.



I chalked this up at the time to them using the same button layout, PCB layout, and remote command IC wiring. The ICs were programmed differently so all remotes could be laid out the same.

As I say, this might not happen any more with any of their remotes. It IS a reason to use the codeset for exactly the model you're programming for!
