The following external bearing, speed, position and way point data is (are) required , when you use the radar func-
tions.

NMEA1 and NMEA2 connectors; See p. 24
•“HDT”, “HDM”, “RMC”, “GGA”, “GLL”, “VTG”, “WPL”, “GNS” and “BWC” are SENTENCES of the NMEA0183.
•If BRG INPUT is set to “GPS”, “RMC” of NMEA2 connector or COG (Course Over the Ground) of “VTG” a bow it
receives as a direction, even if there is no direction information (compass etc.) in NMEA1 connector, the screen
display of the North rise etc. is possible.
However, direction accuracy falls when the speed of a ship is set to 2 or less kts, or when exceeding 3 kts a bow
it does not receive as direction data. Moreo, the influence of measurement position accuracy or a current an actual
bow it may differ from a direction.
