To change frequency, Push and hold Sat until the other buttons light, pick some address and hit # key. To make the receiver respond to the remote at the new address, push Record button on remote when the receiver is at the Sys Info screen. TV1 or TV2 should display the new address on screen. It might be easiest to get to Sys Info before changing remote address.
EDIT: I was quite wrong on the 1st paragraph - they do have to be different addresses. I've deleted it.
