DCH6200 admin menu?

I have a Motorola DCH6200 and a UR5U-8720L-AB remote with atlantic broadband. We had a guy sent over to replace our cables to fix our HDTV reception. He hit some button combo on the remote to get to a gray admin screen where he changed the resolution for the box so that it stretched everything on non-hd channels. I asked him to change it back and I think he set it back to 480i instead of 480p. Does anyone happen to know the button combo for that menu or any other way to change that setting?
