I have a valoin Cassette to MP3 Converter connected, and the instructions say to click the Record button in Aud, after I start the tape, but I cannot see the Record button in Aud.
Note that the picture is interactive. If you hover your mouse over the big square button with the red dot, you will see a “tool tip” appear that says “Record Button”. If you click on the image, it will take you to the section of the manual that relates to what you clicked on.
