I know you are teasing, but this is like deja vu all over again.

I always turn off my 8700 with the button when I'm flying. I never have done it via the screen icon. So just the other day a buddy comes barging into my office demanding I explain this to him. "What the heck are you talking about," I ask. So I look, and by golly there is Turn Off and Full Power Off. I don't have an answer. So I test. And what do you know? Full Power Off is full power off and turn off is turn off as if the user did it with the button.
