OK. OK. I get it. It was a silly question that could have been avoided had I read the manual.
In my defence, I bought the camera Tuesday, and opened it up to look at it that evening. I wasn't planning to actually charge it up and start into the manual until Saturday, since my job keeps me quite busy during the week.
I would have come across the info about how the lock button works eventually.
Now, my mind is at ease and I can realize my overreaction.
