As was alluded to, the official procedure for this system is to:
1- "Wake" it up when we step onto the plane for its first flight of the day.
2- There is no 2
That's it. Honest! There you have the sum total of our interaction with troubleshooting or resetting. We are not even really supposed to do that 'reset' in flight because it may not do a dang thing, and it's not really a reset anyway---we don't know because there is no procedure for that.
