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.

plotter displays). It can only be inscribes from the main window.

of the external equipment. Each press of the [EVENT] key outputs event marker
position. For details see TARGET L/L on page 5-11.
