How to Activate Own Ship Check

Calculation of own ship predicted movement area is
done using a check area about own ship position. Set
the check area as follows:
1. Select the [Check Area] page from the [Overlay/
NAV Tools] box.
Note: The [ON] button may not be shown depend-
ing on installation setting.
2. Set the ahead time or distance and ahead width, referring to the figure below. Al-
so, set the "Around" figures: port, starboard, bow and stern check distance. The
reference point is the conning position (CCRP).
Bow
Stern
3. To select the objects to use in chart alerts, click the [Chart Alert] button and see
section 8.1.2.
4. To show or hide the chart alert area figure, click the [Chart Alert] button to show
[ON] or [OFF]. Any Alarm or Warning chart object in the chart area is highlighted
in red. Chart objects assigned Alarm status additionally give the aural alarm.
5. Click the [Apply] button to affect changes.
Note: When the button to the right of the [Chart Alert] button is not displayed, this
means that the own ship check is active always.
When an object having a Warning setting enters the Check Area, the object is high-
lighted in red and the aural alarm sounds.
