Warnings
Warnings turn on and off repeatedly. The more urgent the warning, the shorter the time between on-off
occurrences: a warning that repeats every two seconds is more urgent than a warning that repeats every
thirty seconds.
As with alarm events, warning events are distinguished from one another on the instrument display
screen using different symbols (see the Product Manual for a complete listing).
