How do you make the FM tuner work on a Yoshima MP4 player?

Start the FM radio app, use your finger or stylus to tap the left or right arrows at the ends of the radio dial until you hear a station that is clear. Make sure that the volume is loud enough. The FM reception in this model is poor, so the station will have to be close or have a strong signal. I live in San Diego, but could only get about 7 stations!
