The unit also indicates its alarm state by the use of the front display.
When in status view, the current alarm state is shown in the top right
hand side of the display. If several conditions exist, the most severe
(alarm) is displayed, i.e. “Video: Err in stream”. If no alarms are present in
the system, the top most warning will be displayed.

”
on the topmost line of the LCD.
