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 Zeus
2 is navigating an active route. If you are not navigating
an active route the heading up orientation will be used until the navigation function is
started.
Positioning the radar center
You can move the radar PPI (Plan Position Indicator) center to different positions within the
radar panel, and select how your vessel symbol moves on the radar image.
Radar motion is indicated on the upper left corner of the radar panel as either TM (True
motion) or RM (Relative motion).
The radar position can only be changed when the radar is transmitting.
Center Look ahead Custom offset
Center
Default setting. The radar PPI center is centered on the radar panel.
Look Ahead
Moves the radar PPI center to the bottom of the panel to maximize the view ahead.
Offset
Allows you to move the PPI center to any location on the radar panel.
1. Select the offset option from the menu
2. Move the cursor to where you want to position the radar center
3. Confirm the setting by selecting the save offset option in the menu.
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 repositioned in the
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 the center of the
screen.
EBL/VRM markers
The electronic bearing line (EBL) and variable range marker (VRM) allows quick
measurements of range and bearing to vessels and landmasses within radar range. Two
different EBL/VRMs can be placed on the radar image.
The EBL/VRM is by default positioned from the center of the vessel. It is however possible to
offset the reference point to any selected position on the radar image.
When positioned, you can turn the EBL/VRM on/off by selecting the relevant markers on the
data bar, or by deselecting the marker from the menu.
