connector to remove the covers of the
power and display unit.
2. Remove all connectors from SPU Board
(SPU-9180).

Navigation aid, video sounder
connection
If your navigation aid can output data in
NMEA 0183 data format, your vessel’s po-
sition in latitude and longitude, the range and
bearing to waypoint, speed, and course may
be input to this radar, and be seen in the bot-
tom text area.
Further, if your video sounder can output
depth in NMEA 0183 data format, depth can
be displayed on the navigation data dis-
played in graph form during stand-by.
You will need an NMEA cable:
