If you're disconnected from the dish you will get the 775 error and the receiver will stop there. You need to keep the dish connected while the receiver is going through the setup. Never mind if it is pointing to anything. Wait until it goes through the entire process and it will start receiving satellite info and immediately give you searching for a satellite. When that happens you can hit the menu button and go to recordings. It will not work without the dish attached and the power inserter on to feed the LNB. Chuck
