Hello all,I have a 90cm dish with a geosat pro 120 motor and fortec mercury 2 box,when I first set up the lat & long positions for install I mistakenly put in the wrong numbers and I can't seem to get back into the same screen to enter the correct install position.every time I hit okay on usals the screen goes blank for about 10 secs then defaults to daystar ch 1. I have done factory reset ,No good still same thing. when I push diseq1.2 I get the goto screen but no Lat & Long input settings. Is there a master reset code or something else beside the switch on back,that I can do? Your help would be greatly appreciated.
