Reference Manual Part 2

137 Chapter 11: Radar
The presentation softkey on the radar toolbar gives you control
over:
Waypoint behavior
EBL
Radar mode and display orientation
Range rings
AIS
These radar settings are locally applied, which means they affect
only the scanner and display on which you are working.
Orientation
Radar orientation refers to the relationship between the radar dis-
play and your direction of travel. There are three orientation modes:
Head up
North up
Course up
These orientation modes are used in conjunction with motion
modes (see
page 138) to control how your vessel’s progress is
shown on screen.
Heading-Up (H-UP)
This is the default mode for the radar application.
North-Up (N-UP)
If heading data becomes unavailable while in this mode, a warning
message will be shown, the status bar shows North-Up in brackets
and the radar uses 0° heading in relative motion. When heading
data becomes available once more, North-Up mode is reinstated.
It is not possible to select Head Up mode when the motion mode is
set to True.
Ship's Heading Market (SHM)

heading) is upwards
