When I was going to the University of Washington School of Music in the Fifties, each classroom had a phonograph. It sat there in a large, nicely finished wooden box, and to get at it, you first had to lift the lid. Pasted under the lid were the instructions for use. The first instruction was "Lift lid."
But there's more. It went on to explain how to place a record on the spindle and carefully place the needle on the first track. The next instruction was "Press 'Start' switch." The instruction following that said, "Make sure machine is plugged in."
