Figure 2-28 Horizontal/Video Plotter display
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. To display track on the
horizontal display, the tilt angle must be less than 75 degrees.
You may switch control between the horizontal display and the video plotter display with the
[MAIN/SUB] key. The message MAIN WINDOW CONTROLLABLE or SUB WINDOW
CONTROLLABLE appears with each pressing of the key. A red rectangle circumscribes the sub
window when it is selected. With the video plotter display selected you may change its range
with the [RANGE] control.
Note: Controls other than RANGE may only be operated from the main window. When you
attempt to operate them when the sub window is selected the message SELECT MAIN
WINDOW appears.
The video plotter display cannot be adjusted.
