Set the Time-of-day (TOD) using the HR (hours) and MN (minutes) push-buttons. An initial delay of 2 seconds occurs after the first button depression before the unit enters the time set mode and the time starts to advance.

^ When the time set mode begins, the display shows TOD along with an A (AM) or a P (PM).
^ Pressing HR causes the hours display to increase.
^ Pressing MN causes the minutes display to increase
^ Reset the clock if the electrical power is interrupted, for example by one of the following conditions:
