Hi, I am dog-sitting for some friends for a few days, and I can't for the life of me figure out how to turn on the closed captioning on their new Sharp Aquos TV. (Sorry, I don't know the model number) There is no CC button on the remote. Under the menu I found closed caption options where you can choose the font and size etc., but I can't find anything that says how to just turn it on! Anybody else have one of these TVs? I tried looking at some manuals on Sharp's website, but it wasn't much help without the model number. Thanks for any help.
