Event marker data
The horizontal display appears in the main window; the video plotter display, which traces ship's
track on the display, in the sub window. Compared to the horizontal display the video plotter's
range is much longer. For example, an event marker entered on the horizontal display
disappears from that display when it goes out of the current range. However, it remains on the
video plotter display for a much longer time when a long range scale is used. This can be useful
when you want to return to the location denoted with an event marker.
The video plotter scale can be changed (setting range: 500-5,000 meters) with "TRACK DISP"
on the RANGE-SONAR MODE menu. For details see page 5-13.
The video plotter display cannot be adjusted.
* Requires appropriate
sensor.
