Its happened twice. once each on two separate RX's. (I have two planes)

I was going to squeeze one last flight in last sunday and when I turned on the TX it said BIND.

What would cause this? and could it happen in the air? both times it happened when I turned the TX on.

I admit its conceivable that the trainer switch was on when I turned the TX on and I believe this would cause it to go into the bind mode...
It was starting to snow, it was cold and I might not have noticed that the switch got hit????

But I dont think so?


Is that the only way it would lose its bind?

A little scary if this were to happen in flight???
