George, I'm not too sure of this but I think you are looking at the preset buttons on your radio. If I'm right what you need to do is turn on your ignition (no need to start the engine) so that the radio lights up; then button 1 keep pressing until the 0 displays, then button 2 until the 2 displays, button 3 until the 7 displays then button 4 until 1 displays. Finally press button 5 to save the code to the radio. Good luck.
