In-store display won't go away on Panasonic Omnivision?

I have a Panasonic Omnivision 4 head vcr tv combo fm radio. I undid the coaxial cable from the back of my tv, then put the cable back into the back of the tv. Now, there is a blue rectangle toward the bottom of the screen that scrolls phrases in it like "Panasonic" "combination vcr/tv" "easy to use" as if it is on display at a store. I don't know what I did to it, but I assume there is some sort of combination code where I need to hold down certain buttons to deactivate the mode. Can someone help me?
