Status display icons
To the left of the A-scan, below the measurement line,
there is an area for various status displays. The status
display icons inform about active functions and certain
settings (see Section Status display icons, page 0-7 at
the beginning of the present operating manual).
Alarms
You can display an alarm signal in the form of a virtual
LED in the far right box on top of the A-scan (see Sec-
tion LARGE (alarm signal), page 5-64).
When an alarm is triggered, the color of the alarm signal
changes from green to red.
