[. . . ] For example, an event marker entered on the horizontal display disappears from that display when it goes out of the current range. However, when entered on the video plotter display 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. Like with the horizontal display you can inscribed five event markers on the video plotter display. 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 chosen. 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 chosen the message SELECT MAIN WINDOW appears.
