RCA TV stuck in Hospital Mode

I purchased a dozen RCA TV's from a hotel remodeling job and they're all in the Hospitality Mode. I have remotes for them and I also purchased a master remote (just in case). I need info on how to change to get regular TV channels ;ie - cable/antenna/use the other inputs on the set....etc. Thanks for your time and knowledge. Respectfully, John Kauffman.
