How do you handle batters time?

If the batter is getting set and has her hand up, I hold my hand up, palm towards the pitcher, indicating to not pitch. If the pitcher goes ahead and pitches, I step to the left (for a right handed batter) and declare "No Pitch!!!" You gotta remember, though, the batter has a set amount of time to get in and get set after you tell her to. I don't hold both hands up, like a time out or dead ball, just indicate to the pitcher, to hold on.

This is exactly right and I hold my hand up in all "not ready" cases I see just in case the pitcher isn't checking the batter and to establish a pattern.
And the ball is not dead. If a runner has a brain freeze and walks off during this, the runner is out.
