I see that Maretron’s DSM150, DSM200, and DSM250 displays have a SSC200 configuration setting called "Reset Factory Defaults"; what is this?

Maretron’s DSM150, DSM200, and DSM250 displays have a SSC200 configuration setting called "Reset Factory Defaults", which is used to return the SSC200 to its factory settings. Resetting the SSC200 erases the deviation table, clears the installation offset, resets the installation orientation to normal, sets the variation source back to "NMEA 0183 or NMEA 2000", resets the rate of turn damping period, clears rate of turn calibration settings, returns PGN enable/disable back to the default, and returns all NMEA 0183 settings back to the factory defaults.
