1.7Presentation Modes

This radar has the following presentation modes:

Relative Motion (RM)

Head-up:Unstabilized display. Heading is at the top of the screen.

Course-up:Compass-stabilized relative to ship's orientation. The bearing scale rotates to place ship’s heading (course set) at the screen top at the moment the course-up mode is selected.

North-up:Compass-stabilized with reference to north. Bearing scale is fixed.

True Motion (TM)

North-up:Ground or sea stabilized with compass and speed inputs. Own ship moves on the dis- play. Landmasses and sea are fixed.

1.7.1Choosing presentation mode

Press the MODE key consecutively to choose presentation mode desired. The presentation mode in use appears at the top left corner on the screen.

All modes except head-up require a heading signal, in AD-10 format or NMEA

Note format. If the heading signal is lost, the mode is changed to head-up and the north marker disappears. Further, the heading readout shows XXX.X and the message “GYRO” (AD-10 format data) or “NMEA-HEAD” (NMEA format data) appears in the alarm message display. Restore gyro input and confirm bearing.

1.7.2Description of presentation modes

Head-up mode		Heading Line
	North Marker
The head-up mode is a display in which the line con-
necting own ship and the top of the display indicates own
ship's heading.

The target pips are painted at their measured distances and in their directions relative to own ship's heading. Echoes may be unstable in severe yawing and turning.

A short line on the bearing scale is the north marker, indi- cating heading sensor north.
