Ray,
Have they updated the instructions for installation for the EARC yet? When I replaced my 722 lastr Feb, the instructions were outdated. The instuctions were for a mixed arc system (Dish 500). When I ran check switch I kept getting an error message that I wasn't pointed at the correct satellite. I had to call for help.
It's been awhile since I read the instructions that are included with a replacement receiver, but I know what you're talking about (taken that call many times). I don't think it's been updated though.
After you run a check switch, and try to exit, it pops up with the 060 "The signal you are receiving is not from the satellite you selected...". The way around this is to:
1) Get to the point dish screen (make sure a check switch test has been ran)
2a) For Eastern Arc customers, change the satellite number to 72.7, or 77
2b) For Western Arc customers, change the satellite number to 119
3) Wait for the signal bar at the bottom to turn green and say "Locked - Echostar XXX West"
4) Once locked, select done, it should give the 055 message (says something similar to "is the mounting and positioning of your dish good?"), select yes
5) The receiver goes to the 061 message, downloading new software, eventually ending up on the 129 (needs to be activated) message.
**note** - If the receiver will not lock on signal, hard reset the receiver, run a check switch again, and all will be well.
