Horizontal Display
The horizontal display appears in the main window; the strata display in the sub window.
The strata picture shows bottom undulations in different colors. This is useful in bottom
trawling for avoiding obstructions which may damage the net.
Coverage for the horizontal mode is 360 picture, and for the strata display it is maximum
90 from port to 90 starboard.
The strata display may be adjusted with the [RANGE] and [SECTOR] controls. Press the
[MAIN/SUB] key to choose the main or sub window. 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 can be controlled.
