On the lower right side of the face of your radio are two triangles. One facing up the other facing down. With your iginition on, press and hold your left hand button for two to three seconds and you'll hear a "beep" then you just scroll thru the 12 hours until you get around to the time you need. Use the right hand button to reset the minutes. A few seconds after you stop screwing with it the radio will return to normal mode
