Anatel Operator Manual
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 Table 7-2.
Warning alarms
A warning occurs any time one of the subsystems is not operating at a normal level. When a
warning condition is present, a warning indicator appears on the display. Operation may
continue with a warning condition present. When the warning condition has been corrected,
the indicator disappears. See Table 7-3.
