9.4.4 How to use the Alert Parameters page
The [Alert Parameters] page sets the alert conditions to use when checking a route.
Put a “W” for an item to highlight on the chart. ([Safety Contour] is fixed to “A” (Alarm).
If you do not require the highlight display for an item, put a “C” for that object. The rel-
evant alerts (Alarm, Warning, Caution) are shown in the [Check Results] page.
You can select the safety contour and chart alerts used to check the safety of the
route. This allows you to check the safety with conditions different from those chosen
for system use. This is useful when making a route for different loading or sailing con-
ditions.
