I am using the 922 and the numbers seem to have me locked out. I have read and read, tried many different things but the dish will not move even under installation. It is set on 5000 and everything I do will not let the dish move under any circumstances. I have tried out the dish with another receiver and it will operate. Something I am doing is not helping the situation. I really want to use the 922 as it is a better receiver. I would appreciate feedback---please.
