4.8 Event Marker
The event marker functions to mark important locations on the echo sounder display, 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, at own ship position always.
Note 2: Event marker position can be output to external equipment. For details see
TARGET L/L on page 5-10.
Note 3: Event markers are automatically erased as they move off the screen with picture
advancement.
