Radar Overlay Range Link

The radar overlay range link automatically keeps the chart scale and radar range in
sync. This feature helps you understand the relation between the radar and the chart.
You can activate or deactivate this feature from [Plotter Display]. See paragraph 3.2.3.
Note: The radar picture can look "out of focus" on long ranges when the range link is
active. This out of focus appearance does not indicate a problem, because it is a char-
acteristic of the digital zoom.

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.
To get the dual-range display, set dual-range displays in the display selection window.
See section 13.2 for the procedure. You can put the dual-range displays in the two-
way and three-way split screens.
The radar functions that are adjusted separately are as follows:
• Active route (show or hide)
• Rain (rain clutter)
• Heading line and rings (hide temporarily)
• Range
• Orientation mode (head-up or north-up)
• Auto sea mode ([Advanced] or [Coastal])
• Transmission* (Can not set stand-by mode separately)
*: The no.1 screen is independent of the no.2 screen when the no.2 screen is in stand-
by. However, when the no.2 screen goes to transmit state, so does the no.1 screen.
