My HR24 arrived today. I can't get it installed, each time I'm getting a 771 Satellite Signal "2" (I presume line 2) error during setup. Now I did take the BBCs off an HR21 in another room and I put them on the HR24. I also tried switching SAT 1 with SAT 2 and did a RBR, and I get the same 771 error during setup. The HR21 is replacing a legacy unit that was working before I tried to install the HR24. Also, my HR21-700 is in the same rack and it is getting signals just fine. So that seems to rule out a signal problem from the switch outside to the satellite dish. Can anyone help me as to what to try next?
