I have Sony HD100 with remote rm-y808 and Sont T60 with remote rm-y809. Both receivers are in same room. I need the remotes to only control one receiver. Now each remote controls both receivers.

The T60 has a choice of three different remote addresses. Address #1 being the standard sat code, so you need to change to address #2 or 3. Here's how;

1. Menu> Mess. & Setup> System Info>
2. scroll down until you see REMOTE ADDRESS
3. While pointing the tivo remote away from the receiver, press and hold TIVO & PAUSE, until the red light remains on.
4. Press either #2 or 3, which changes the tivo remote.
5. Now point the remote towards the receiver and press the right directional key, the REMOTE ADDRESS should change on screen.

Remember never to use the HD100's remote when you're in the T60's INFO SCREEN, it'll change the T60 to the same remote address as the HD100 again.

When I press menu , mess & setu , and System Info, I get a screen with text info of my system but no options to scroll down.

When you're on the info screen, use the channel down key to scroll.
