Alarms
A number of conditions will trigger an alarm and a corresponding message to
appear in your Workboat Navigator application window. Workboat Navigator
provides a standard setup for alarms but your installer may have customized your
alarms to suit your needs. The location of the alarm depends on the current view
configuration but they generally appear in the top middle portion of your monitor’s
configuration. As long as the condition exists, the alarm will continue. You can
clear the alarm by acknowledging it. For many alarms, if the condition still exists 30
seconds to a minute after you acknowledged it, the alarm sounds or appears again.
To acknowledge an alarm, select it with your pointer and left-click your mouse. You
can also use the Hot Keys
F1 , F2 , F3 to acknowledge alarms, with one
being the first alarm in a sequence and three being the third alarm in a sequence.
The following table describes the alarms and their conditions.
