  2. While either the hour or the minute numbers are flashing, turn the tune knob, located on the upper right side of the radio faceplate, clockwise or counterclockwise to increase or decrease the time. While the 12HR or 24HR time format is flashing, turn the tune knob clockwise or counterclockwise to select the default time settings.
  3. Press the clock button again until the clock display stops flashing to set the currently displayed time; otherwise, the flashing stops after five seconds and the current time displayed will be automatically set.
