(printed as the HRI character, but not encoded.) ❏ The start codes (CODE A, CODE B, CODE C) and the stop code are added automatically. ❏ A symbol character FNC1, which is described after the start code, is automatically added. ❏ When FNC1 is not at the end of the data followed by the application identifier ‘(30)’, FNC1 is automatically added. ❏ FNC1 must not be at the end of the data followed by the application identifier ‘(10)’ or ‘(21)’. In this case, an error occurs.
