Sumless NMEA:
Select whether or not to load a sentence with or without checksum. Basically,
sentences are without checksum in case of NMEA Ver.-1.5 while with checksum in

Nav data is inputted from the INS, set the speed according to the specifications of the
INS.
3. Select [MENU] -> Initialize 2 -> Sumless NMEA.
