12.7 Radar mode and orientation
Radar orientation modes
The radar can operate in a number of orientation modes to suit
different types of navigation.
The orientation of the radar refers to the relationship between the
radar and the direction that you are travelling in. There are three
orientation modes to choose from:
• Head-Up
• North-Up
• Course-Up
These orientation modes are used in conjunction with motion mode
to control how your boat and radar relate to one another and how
they are displayed on screen. Any changes that you make to the
orientation of the radar are retained when you switch off your
multifunction display.
Head-Up
This is the default mode for the radar application.
