W: I used cassette recorders a lot when I studied French in high school.
M: Good. There are many kinds of language labs. Ours is a small one and it’s fairly easy to operate. And this is the main control panel. You can set the controls to allow students to listen to the lessons they want to hear.
W: I sec. What are these?
M: These are the system operates. Most of the lessons are on cassette tapes, but some of them are also kept in order on the shelves and they are clearly marked with the language and lesson number. For example, the cassettes in the green boxes are French lessons. Records and long tapes are over there.
