BASIC OPERATION

■ Ship speed indication

When the ship speed data in NMEA 0183 format is ap-
plied, the radar can display the ship speed. Knots (KT)
or kilometers/hour (KM/h) are automatically selected
in the normal screen (p. 3) by selecting nautical miles
(NM) or kilometers (KM) respectively.

■ Bearing setting

The radar bearing interface accepts NMEA, N+1, AUX
or COG data format and the bearing can use a mag-
netic or true north type. When a true north type bear-
ing is used, the variation from magnetic north, etc.,
can be adjusted on 0.1˚ steps.
