Alarms
7.4.2 Critical error alarms
A critical error occurs any time the analyzer cannot function due to an error in the system.
The error appears as a full-screen, flashing message. All operation ceases until the error
condition has been corrected. The current analysis is aborted. Touching the screen
provides access to the alarm acknowledge dialog box. See
.
7.4.3 Warning alarms
A warning occurs any time one of the subsystems is not operating at a normal level.
