Control Marantx AMP with IRRemote

Good day everyone.
I try to control some devices with IR, all was best but I take a problem with my Reciver Marantz SR 5003. On the production web site write that this reciver user RC5/RC5X protocol, but when I try to use IRDumpDemo library can`t decode IR Code, I got a document where present all possible commands for my reciver in very strange format:

Command Name System Command Extension
POWER ON 16 12 01
MENU 16 82 60

Does anybody know how to convert this data to Hex format fo IRRemote Library. Idon`t understand what is extensions, and how i can transit it,because in protocol description present only adress and command.

In Attach file codes for commands on Excel format.

With greate thanks, Maxim.
