Thanks for trying Chris – I think I’ve managed to ‘Sherlock’ it out! For some strange reason all the English operating manuals on line that claim to be for the ‘HE’ version are actually for the ‘FE’! I managed to find an Italian ‘HE’ one and comparing the ‘VP’ manual with them both, it clearly is equivalent to a ‘FE’. The main difference is apparently that the FE (and VP) have 10 bit processing whereas the HE has 12 bits.
FWIW
