400A series clocks may be programmed to synchronise to EBU/SMPTE time code signals when the optional
404.E interface is fitted. Calendar clocks may be synchronised to one of two date formats. Format 1 (*)
is desgined to work with other manufacturers' displays - eg Leitch (TM) whereas Format 2 (**) displays time/date on a
video signal in an understandable order. Both formts work with V-401A/V-420A/V-490A Time Displays (ie no date)
