Troubleshooting radio/CD player

Where can I get a manual for Gen 3 radio/CD players? My owner's manual has nothing about it.

 

Thanks, I'll look it up!

Found exactly what I needed. This is it. Now I've programmed most of my radio stations back in. The only one missing is the Classical FM station, but the radio reception for it is too weak here at home.
