				HDG	Heading alarm, 0.5 A max, normal close
				alarm
	HDG IN	MJ6	I	Heading	Heading data in either AD10 or IEC 61162 (NMEA
					0183) format (4800 bps) is automatically received.
					Priority of IEC 61162 (NMEA 0183) sentence is
					HDT>HDG>HDM.
					The signal is selected through the menu during the
					period of internal heading sensor failure.
					VBW/VHW/VLM may be input from a current indicator.

Note: Each GPS receiver GPS1, GPS2, and GPS3 calculates VTG/GGA/GLL/ZDA. The output from HDG OUT and NAV OUT ports is one calculated by the GPS1. However, when the GPS1 is defective, the GPS2 replaces it. When both GPS1 and GPS2 are defective, the data calculated by the GPS3 is used.
