Setting Time of Day

Time-of-day (TOD) is set using the hour (HR or RRS) and minute (MN or MIN) pushbuttons. There will be an initial delay of 2 seconds after first button depression, before the unit will enter the time set mode and the time will advance.
^ When the time set mode is entered, the display will show TOD along with an A (AM) or P (PM).
^ Pressing HR or HRS will cause hours to increase, while pressing MN or MIN will cause minutes to increase. If the electrical power is interrupted by a blown fuse, discharged battery, etc, the clock must be reset.
