Understanding the Radar Overlay Screen
The radar overlay screen places the radar picture directly onto the navigation chart.
To access the radar overlay screen, from the Home screen select Radar > Radar Overlay.
Radar Overlay Screen
Map scale
Radar range
The radar picture appears in orange and overlays the navigation chart. Use the RANGE (+/-) keys to
zoom in and out:
Zooming while panning the map will only effect the zoom scale of the map - the radar range
remains the same.
Zooming while the map is locked on the boat (not panning) will effect the zoom scale of the
map as well as the radar range. When you reach the limit of the radar range, the screen will
not zoom out further.
Radar overlay screen options
To access additional settings or options for the radar overlay screen, press MENU. There are two
sets of options you can access, radar or chart. The radar setup options are the same as the radar
cruising screen (page 44). Select Adjust Chart to access the chart options. The chart options are the
same as the navigation chart (page 12). Select Adjust Radar to return to the radar setup options.
