It's supposed to come factory pre-set to operate my SONY receiver, but I can't even get it to operate a function as simple as "test tone" right out of the box. Now, I realize that i can make it learn many of the functions of my STR-DE925 remote, but I didn't think I'd have to go through all of that. More importantly it seems that there are some functions of my STR-DE925 remote that I don't think this thing CAN learn-- ie: the Soundfield and GENRE selections.... any tips from anyone who's been there? Another question, ... what is an "AIR EGG" remote,..i've read that older model SONY receivers and/or receivers that came with an "air egg" remote will not work with this model universal remote. Thanks !
