You use the tuning buttons, until you get a station you want then press and hold the channel number you want it to be on, until it beeps.
And that will set that station.
I know you need to turn the radio off to set the clock, also.
What problems are you having? There's also 3 set's of 6 channel you can use, by pressing the radio button, it goes through, choices 1, 2 or 3.
Hope some of this helps.
