As of a few days ago, our 322 has been displaying the "There's an issue with your switch, run the check switch test...". After each run, all 4 birds are okay, and the receiver works perfectly. You have to run the check switch test when the message comes up, it won't let you ignore it. This occurs at least twice a day with this receiver. Why would it be doing this? There's nothing wrong with my setup, that I know of. Thanks!
