This is actually the 2nd time this message has appeared. And i'm sure i'm prolly not the only one with this question but prior to now, i haven't had a reason to come up here and post a question/problem until now...
As i said this is the 2nd time this has happened, i'm getting a message on my Passport x50 saying "Self Cal" and it beeps and stays on for approx. 2-3 min. (maybe) and then it'll reset and go back into Auto mode.
Can someone explain this please?
