Dell 2400MP Blank Screen Message

I have a Dell 2400MP projector. When you press Blank Screen on the remote, the screen goes black, as it should, but there is a message at the bottom that says something to the affect of "Your projector is on the Blank Screen, to return to use, press the "Blank Screen" button on your remote." To me this kind of defeats the whole purpose of a blank screen if there is a message on it. (we use it in a church setting and the pastor has these words across his chest as he speaks if we use this option. Does anyone know how to get rid of this message?

Thanks in advance for any help.
