Hi i think i have succesfully scratched the talk back on my new pace di4010 box i connected it to the feed and waiting to see if the middle led flashed but it never.. it got stuck on nlt for few mins until it said Er20 then went to 0.. I just searched forums and it says Error 20 means NIT.... Which is part of area frequency so i checked the eng menue and i found it 803.000 Mhz 6.887 and my req and sym is different i thought DAVIC boxes set the freq on auto could someone help me please...
