Horizontal/Video Plotter display
The horizontal display appears in the main window; the video plotter display, which mainly
traces ship’s track, 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 marked with an event
marker. To show 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.
