6.24 Dual-Range Display
The dual-range display scans and displays two different radar ranges at the same
time, with a single antenna. There is no time delay between the two pictures and you
have separate control of each picture. This feature lets you keep a close watch on
close-range targets and far targets.
The radar functions that are adjusted separately are as follows:
• Active route (show or hide)
• Auto shift
• Echo stretch
• Echo average
• Echo trail (activate or deactivate)
• Gain
• Heading line (show or hide)
• Motion mode (true, relative)
• Orientation mode (course-up, head-up, north-up)
• Rain (rain clutter)
• Range
• Range rings (show or hide)
• Sea (sea clutter)
• Tuning (manual)
To get the dual-range display, set dual-range displays in the display selection window.
See section 13.3 for the procedure. You can put the dual-range displays in the two-
way, three-way or four-way split screens.
