Denon didn't plan too far ahead when they printed that manual, did they?
What year do you suppose that receiver was made? 2007 or so? Now, what year wasthat Blu-ray player released? 2010?
I think they can be forgiven for not publishing device codes three years or so before a device is released, don't you?
Maybe
this link might help but, if worse comes to worse, I believe you can program the remote, function for function by some long, laborious process by facing them at each other and pushing buttons is a certain sequence. At least my 2802 allows that, but I never bothered. Check your manual.
Or, does Denon have some sort of firmware update for the remote? Might be worth a call.
