Why don't you just learn the button from your original
remote?

Other possibility: search pronto&marantz file section in this site and search for a ccf for your device (they are listed by brand , type etc...)
Once you find your model (or similar, as the IR codes often remain the same between similar models within the same brand) just download. then merge the ccf with your own ccf file (open your file first!!!!!!!!!!)
Now you can take the IR codes and copy paste them into your buttons. Once done you delet whatever parts of the merged file you don't need anymore.
As you see learning is easier!
good luck
