A display without azimuth stabilization in which the
line connecting the center with the top of the display
indicates own ship’s heading.
The target pips are painted at their measured dis-
tances and in their directions relative to own ship’s
heading.
A short line on the bearing scale is the north marker
indicating gyrocompass north. A failure of the gyro-
compass input will cause the north marker to dis-
appear and the readout to show asterisks (***.*).
Radar echoes are shown in the same way as in the
head-up mode. The difference from normal head-up
presentation lies in the orientation of the bearing
scale. The bearing scale is gyrocompass stabilized.
That is, it rotates in accordance with the gyro-
compass signal, enabling you to know own ship’s
heading at a glance.
This mode is available only when the radar is inter-
faced with a gyrocompass.
If the gyrocompass fails, the bearing scale returns to
the state of head-up mode.

An azimuth stabilized display in which a line connect-
ing the center with the top of the display indicates
own ship’s intended course (namely, own ship’s
previous heading just before this mode has been
selected).
Target pips are painted at their measured distances
and in their directions relative to the intended course
which is maintained at the 0-degree position while the
heading line moves in accordance with ship’s yawing
and course change. This mode is useful to avoid
smearing of picture during course change. After a
course change, press the [CU, TM RESET] key to
reset the picture orientation if you wish to continue
using the course-up mode. The heading line gets
back to scale zero.
