2.9 Event Marker
The event marker functions to mark important locations on the screen, and five may be
inscribed. Each time the [EVENT] key is pressed the “latest event marker” (
) is inscribed
at the cursor location and all previously entered event markers are shown by the “previous
event marker” (+). When the capacity for event markers is reached, the eldest event
marker is erased from the screen to make room for the latest.
Note 1: With position data input the event marker moves with ship’s movement. The
event marker can be inscribed without position data, however it will be stationary.
Note 2: The event marker cannot be inscribed from the sub window (strata, history and
video plotter displays). It can only be inscribed from the main window.
Note 3: The latitude and longitude position of the event marker can be output to a video
plotter and that position inscribed on the plotter’s screen with the external
waypoint mark (X). Each press of the [EVENT] key outputs event marker position.
For further details, see TARGET L/L in paragraph 5.4.2.
Note 4: The tilt angle must be less than 75 degrees to use this feature.
