Relative motion
Your vessel remains in a fixed location on the Radar screen and all other objects move
relative to your position. You can choose the position of the fixed location, refer as
described in
Positioning the radar center .
Relative motion is the default setting.
True motion
In True motion your vessel, and moving targets, move across the Radar screen as
you travel. All stationary objects remain in a fixed position. When the vessel’s symbol
reaches the edge of the screen, the radar image will be redrawn with the vessel symbol
re-positioned in center of the screen.
When True motion is selected, the menu will expand to include a reset true motion
option. This allows for manually resetting the radar image and vessel symbol to screen
center.
The image color
Different colors (palettes) can be used to represent detail on your radar
panel.
Setting the radar orientation
Heading up
Rotates the radar image to display the current heading directly up on the
radar image.
North up
Rotates the radar image with the north direction upwards.
Course up
Rotates the radar image to display the current navigation course directly
up.
This option works only when the vessel is navigating an active route. If the
vessel is not navigating an active route the heading up orientation will be
used until the navigation function is started.
Setting the radar threshold
The threshold sets required signal strength for the lowest radar signals. Radar returns
below this limit will be filtered and not displayed.
Default value: 30%.
Using the cursor on the radar panel
The cursor is by default not shown on the radar image.
When you press one of the arrow keys the cursor will be visible,
the cursor position window will be activated.
The cursor can be used to measure a distance to a target, and to
select targets as described later in this section.
To remove the cursor and cursor elements from the panel, press the
X
key.
