FLIR RAYMARINE E125 - Radar Motion Modes Overview

Item Description
1 True north at top.
2 As your vessel's heading
changes:
• Radar picture is xed
(north up)
• SHM rotates accordingly
Note: If heading data becomes unavailable whilst
in this mode, a warning message will be shown,
the status bar indicates 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.

when the motion mode is set to True.
Course-Up
Item Description
1
Current course upwards.
2 As your vessel's heading
changes:
• Radar picture is xed
• SHM rotates accordingly
If you select a new course, the picture will reset to
display the new course upwards.
The reference used for Course-Up depends upon
the information available at a given time. The system
always prioritizes this information in the following
order:
1. Bearing from origin to destination, that is,
intended course.
2. Locked heading from an Autopilot.
3. Bearing to waypoint.
4. Instantaneous heading (when course-up is
selected).
Note: If heading data becomes unavailable whilst
in this mode, a warning message will be shown,
the status bar indicates the Course Up in brackets
and the Radar uses 0° heading in relative motion.
When heading data becomes available once more,
Course-Up mode is reinstated.

Radar motion modes overview
The motion mode controls the relationship between
the Radar and your vessel. There are two modes:
• Relative motion.
• True motion.
The selected motion mode is displayed in the status
bar. The default setting is Relative Motion with no
offset.
Relative Motion (RM) with optional Vessel Offset
When the motion mode is set to Relative, the
position of your vessel is xed on the screen and
all the targets move relative to the vessel. You can
specify whether the vessel is xed in the center of
the window, partially offset or fully offset to increase
the view ahead, as shown below:
Examples:
Center offset Partial offset Full offset
The default motion mode is “Relative”, with center
offset.
True Motion (TM)
When the motion mode is set to True, xed Radar
targets maintain a constant position and moving
vessels (including your vessel) travel in true
perspective to each other and to xed landmasses
on the screen. As the vessel’s position approaches
the edge of the screen, the Radar picture is
automatically reset to reveal the area ahead.
Note: If heading and position data become
unavailable when True motion is selected, a
warning message will be shown, the mode will
revert to relative motion and be noted in the status
bar in brackets, for example, (TM).
Note: It is not possible to select True Motion when
the orientation is set to Head Up.
