Domestic rules and digi card

slowtrac:
Hi there and I hope I am posting this in the right section,

My work currently has drainage tankers running on gb domestic rules and recording via log books, now the TM wants us to start using our digi cards and set to out of scope. How do you do this as at the moment if the head is set to out of scope and you insert your card, the head returns to EU rules.
Sorry If my ramble dosnt make sense lol

You need to reset the tachograph to out of scope every time you insert your driver card, out of scope resets when the card is ejected.
