Switch the unit on.
Press Menu button,press right button , the next menu should have at the top of the list "add satellite".Press ok, name the satellite you want to add,select universal on the lnb type,select menu to exit. Then go back to the menu with the add satellite on it, move down once to edit satellite and find the satellite you named before. You can do an auto scan on your added satellite to find transponders and add extras later. Selecting an NIT search will let you add individual transponder frequencies to your new satellite too.
