indicator. The annunciator panel status window shows the alarms that are active.
To reset an active alarm, first highlight the active alarm using the navigation keys, then
press the reset button to reset the highlighted alarm. If no indicator is selected, all alarms
on the page are reset by pushing the reset button.
