Description
Heading
A display without azimuth stabilization in which the
Heading
Marker
line connecting the center with the top of the display
Line
010
020
indicates own ship's heading.

The target pips are painted at their measured dis-
060
tances and in their directions relative to own ship's
070
heading.

A short line on the bearing scale is the north marker
indicating gyrocompass north. A failure of the gyro-
100
compass input will cause the north marker to dis-
110
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
Heading
Line
presentation lies in the orientation of the bearing
260
270
scale. The bearing scale is gyrocompass stabilized.
280
That is, it rotates in accordance with the gyro-
290
compass signal, enabling you to know own ship's
300
heading at a glance.
310
320
This mode is available only when the radar is inter-
330
faced with a gyrocompass.
340
350
If the gyrocompass fails, the bearing scale returns to
000
the state of head-up mode.

An azimuth stabilized display in which a line connect-

own ship's intended course (namely, own ship's
030
040 previous heading just before this mode has been
050
selected).
060
070
Target pips are painted at their measured distances
080
and in their directions relative to the intended course
090
which is maintained at the 0-degree position while the
heading line moves in accordance with ship's yawing
100
and course change. This mode is useful to avoid
110
smearing of picture during course change. After a
120
course change, press the [CU, TM RESET] key to
130
140
reset the picture orientation if you wish to continue
150
using the course-up mode. The heading line gets
160
170
back to scale zero.
