Hello, I have an mp3 player, I recorded a meeting on it. I had a friend convert it into cd's, but the cd's only play on my computer and they won't play on my cd player radio, and they won't play in the car. I was told its the way they were recorded I believe they are in a file called "act" and "wave" I'm trying everything to try to transfer the meeting onto regular cd's that will allow me to play on a cd radio and in the car. Is there anyway you could assist step by step in doing so. thank you

there is no manual,

You can't. Cassettes are analog and the USB only recognizes MP3. The USB will only record off a normal CD or a CD with MP3s on it. It won't record other formats. The unit only allows to record from CD to cassette or from CD to USB. There are some cassette decks that will convert to MP3. Just do a search for "cassette to MP3 converter"
