what’s the procedure on this?
i started on analogue, filled it (ok, forgot the end mileage), then moved onto digi and did not bother with manual entries as my thinking was that it had already been recorded on an analogue chart.
ideally this should have been asked beforehand 
but tbh i did not really expect this pattern
Just keep chart for 28 days then hand to transport manager
Also just keep eye on driving time 
You did the right thing, well apart from not putting the end mileage on the chart anyway
When you used the digital tachograph, if it was a type 2 where you have to account for all the time since the card was last ejected you should have used the ? symbol for the time the card was out since the last digital shift.
cheers, probably was class 1 as t did not ask to fill the time since last withdrawal
