4.8 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: The event marker inscribed on the echo sounder display will also be inscribed on the
horizontal and video plotter displays. However, the mark is always inscribed at own
ship position on the horizontal and video plotter displays regardless of the location of
the mark on the echo sounder display.
Note 2: 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 3: Event markers are automatically erased as they move off the screen with picture
advancement.
