Had to install my replacement 722 yesterday. The included instructions do not reflect the new EARC dish. It wanted me to aim at 119 for a Dish 500 and do a Check Switch. Could not get past that. Had to cal tech support and was told that all I needed to do was point to 72 and wait till the signal was acquired and select Done. Also. there should be instructions not to connect the EHD till everything is back up and running.
