NEWSPEAK?

Some time ago I was in the hospital waiting for a treatment much like an X-Ray (I have had I think every known type of scan lately this past year or so and they all merge into one after a while) and I sat in the waiting area across from this sign. I was there for four hours or so and began to stare at this sign. Is it intended for me I wondered? I had no idea but the more I stared the less sense it made. Perhaps it was for staff?

I am considered a relatively intelligent man but the more I looked the less I understood. What DOES it mean? What is one supposed to do?

 Your comments would be appreciated.
