2.9 Event Marker
The event marker functions to mark important locations on the screen, and five event markers
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 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 inscribes from the main window.
Note 3: Event marker position can be output to external equipment and marked on the display
of the external equipment. Each press of the [EVENT] key outputs event marker
position. For details see TARGET L/L on page 5-11.
Note 4: The tilt angle must be less than 75 degrees to use this feature.
