Entering Radio Code?

I have a Cabasse Auditorium Tronic. I need to enter the code. I have figured out how to enter it with the thumb wheel thing and move to the next digit but do you need to do something like 'ok' to proceed? Will it just automatically kick in when I enter the last correct digit? I'm not sure if my code is right you see or if I am doing it wrong.



This is the exact radio I have model 22DC279 / 62E
