You need to check your manual for this. In case you don't have one, a copy.
You might want to save a copy to your computer. Trust me, you're gonna need it.
Again, you need to check the manual. Be aware that you might be limited (or at least handicapped) as to what you can do with a remote. It might behoove you to search one out.
A fine receiver for cheap ain't no bargain if you can't access the most useful features. That's like being married to a beautiful woman who won't let you touch her.
I could be wrong, but I think the most you can get out of this is two-channel stereo, and maybe use DPL for fake multi-channel.
enjoy...
