This manual looks like it's written by the same guy that wrote my JVC manual. It is about a pain in the butt. Anyways, I wanted to add, make sure you have selected a Zone 2 source that has a signal playing on it. The Main room fronts should still be playing whatever source you have selected in the main room, but you also need to select a source for the zone 2 room (outdoor spkrs). That way, someone can watch TV in the main room, while someone is listening to music outdoors.
BTW, I don't mean to sound condesending, but I think it does sound that way as I read back over it. I'm just trying to help, and I am not sure how experienced you are with the equipment.
Hope this helps,
Mark
