I see that Maretron’s DSM150, DSM200, and DSM250 displays have a TLA100 configuration setting called "Reset Factory Defaults"; what is this?

Maretron’s DSM150, DSM200, and DSM250 displays have a TLA100 configuration setting called "Reset Factory Defaults", which is used to return the TLA100 to its factory settings. Resetting the TLA100 resets the tank type back to "Fuel", resets the tank number back to "0", resets the operating mode back to "NMEA 2000", resets the gauge resistances back to their default values, clears the tank capacity, resets the tank level calibration to the American standard, and returns PGN enable/disable back to the factory default settings.
