I had this the other day came up error 50 and just pressed ok. Got no further warnings. Carried out my shift and got a printout at the ènd of the day and no problems on ejecting the card. Can I take it that it is all ok now. Not working now till Wednesday so will have to see then.
I get that on mine, still records the data fine. I think its just a buggy unit.
