I am soon to upgrade a 942 to a new 722 receiver. Is this a self install? I have the 942 at a "moved" address so I can get the Atlanta locals in HD. I plan on ordering the 722 on the 15th, but am not sure what I need to do. If self install I can tell Dish to send the receiver to my billing address. If not, will I need to move for a few days?
