press the RECALL button [lower right side], while pressing the TUNNING button [ you'll notice an [H] and [M] on either side of the TUNNING button. I think the raidio has to be on?
1) turn radio OFF
2) HOLD "SET" button
3) PRESS "SEEK" to change hours
4) PRESS "SCAN" to change minutes
5) RELEASE "SET" button, when seconds round to 0 (it sets the start for the minute you entered)
Good luck
