First off, line N and O aren't used for anything in option 4 , 7. Only line C & E once the dish has already been aligned just to check .the final signal.
If you are trying to align it by yourself use Options 4, 3, 1 for the tuning bar. These new receivers won't show anything until you find the signal. The old receivers were the ones to start at some where's between 10 & 20 but that only told you the cable was attached to the dish it read zero if the line was broken etc.
Tuner 1 is the only one that wil show when you lock in on the sat until you are activated and after 10 minutes or more then you can change channels and the 2nd tuner will light up.
If you have a sat finder meter it will go easier and faster, but if not move the dish very slow from east to west and keep your eye on the tv. like move it a fraction and wait a second or 3, the bar will go up once you get close to the right sat.
If you don't find anything raise the dish by 1 or 2 notches at the most and start moving east to west again and so on until you get lucky

Key is to go real slow if you don't have a sat finder.
If this receiver has been activated already before you moved there, then try tuning in on ch 700.
Good luck
