Yeah, that was something the three of us at the Saturday meet worked out. You can activate the phrases with a slight pressing of the chest panel, but you need to push it all the way in to move the head. And the head only moves as you push the chest in, it doesn't keep moving while it talks (like Supreme Optimus). If the head still doesn't move when pressing in the chest panel all the way in, then you probably have a faulty one.
