After making a bunch of configuration changes, I can't seem to get into the 990 Main Menu. I am trying to change my CD to use Opt3. When I press the menu button on the 990, nothing happens; the remote (although it will perform many functions) doesn't seem to allow me into the menu either.

I might be forgetting some simple step. So, is my 990 malfunctioning, or is it me??

Thanks.
