Ernie,
Go to this site and plugin the values from the PDF.
For example:
7F01-5E20
FYI, there was a Yamaha RXV1 or RXV800 CCF/Spreadsheet in the files section that has all the standard/extended codes for Yamaha Receivers. But from the PDF, it looks like they may have extended their format slightly to include more codes.
