3.4.6 Switch True/Relative Motion Display Mode (TM/RM)
3.4.6.1 Switching Relative Motion (RM) Mode to True Motion (TM) Mode
Procedures
1) Left-click the motion mode button located at the upper left of the
radar display.
→
The true motion mode will be selected. In the true motion mode, the own ship
’
s position on
the radar display moves depending upon its speed and course and the influence of the
current. Land and other fixed targets are fixed on the radar display and only actually moving
targets move on the radar display. When the true motion mode is selected, the own ship
’ s
position is set to about 60% of the display radius in the opposite direction to its course
allowing for the influence of the current. Own ship starts moving depending upon its speed
and course and the influence of the current. Subsequently, when own ship arrives at the
position of about 66% of the display radius, it is automatically reset to its initial position at
about 60% of the display radius in the opposite direction to its course allowing for the
influence of the current.
