11.2 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 de-
pending 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).
3. To select the objects to use in chart alerts, click the [Chart Alert] button and see
paragraph 11.1.2.
4. To show or hide the chart alert area figure, click the button ([ON] or [OFF]) to the
right of the [Chart Alert] button at the bottom of the [Check Area] page.
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.
