The Event Mark
The event mark is useful for finding the horizontal range, depth
and bearing to a location some distance from current position.
This function requires speed and heading inputs.
There are two types of event marks: event mark 1 and event
mark 2. 10 of each type of mark can be displayed. The unit marks
the latest one by (
) for event mark 1 and by ( ) for event mark
2. Older event marks are displayed by a cross plus event number
(event mark 1) or an inverted Y with event number (event mark
2). When you enter more than ten event marks, the unit erases
the oldest mark, one by one.
