3.3.7 Selecting Presentation Mode [PRESENTATION MODE]
This control switches presentation mode from [Head Up] to [Course Up], [North up] to [Stabilized Course
Up] every time the switch is pressed.
The current presentation mode is displayed as "HUP", "CUP", "NUP" or "SCUP" on the upper right of the
screen.
AZI
MODE
The presentation mode that can be used vary according to the motion mode.
See subsection “3.3.8 Selecting True Motion／Rative Motion Display Modes [TM／RM] [TM RESET]”
.
"HEAD UP"
The heading line (HL) is always pointed vertically to the top center of the radar display (0 degree on the
bearing scale). Since targets are displayed in the directions relative to the bow, the operator can sight them
on the radar display in the direction he really sees them.
When the own ship traverses, the surrounding targets are rotated at each scan.
"COURSE UP"
Selecting "COURSE UP" places the heading line (HL) on 0 degree on the bearing scale. As in the case of
the NORTH UP, stationary targets remain stable on the radar display and the bearing of the HL changes as
the own ship changes its course. After the own ship course is changed, the new course can be updated by
pressing the switch three more times to select the COURSE UP display or pressing the
HL
OFF
key.
Surrounding targets will not ratate according to the traversing of the own ship.
"NORTH UP"
North is always at the top of the screen (0 degree on the bearing scale). The merits of this presentation mode
are as follows: Stationary targets remain stable and can be easily found on the chart, and their true bearings
can be read immediately.
Surrounding targets will not ratate according to the traversing of the own ship.
"STABILIZED COURSE UP"
The heading line (HL) is always fixed at the top of the screen (0 degree on the bearing scale) by resetting it
every rotation. During video processing, the fixed target is displayed stably and unnecessary targets such as
sea clutters decrease. This display is available only in the radar mode.
Surrounding targets will not ratate according to the traversing of the own ship.
