I wasn't certain that it has an FM radio on it, so I searched the web and it seems to be yes it does. If this is the case you will need a radio aerial, once you have that plugged in, you select the tuner option and tune the stations in that you want.

If radio has save button then tune your station push save button then push a number on preset you want it saved to. The radio automatticlly stores the strongest station in your area.

Select the AM or FM wave band.
Tune the radio to a station then press and hold down the 1 or 2 or 3 pre tune station button until it beeps. Then this radio station is then set to which pre tune button you have selected.
Repeat to set the buttons for other radio stations.
