The four arrows on the front of the instrument are used to navigate within the interactive menu bar. The AZ/Stop key has a dual function; it can be used to auto zero the ELSD at any time, unless a timetable is running. If the AZ/Stop key is pressed during an active timetable, the timetable will stop running and the ELSD will revert to STANDBY mode.
