Try reading just the NLU file back from the cash register to CV21 and see if it fixes the file.
Otherwise, I'd try setting the file size to 0 then back to 10 on the cash register to clear any NLU entries, then read the file back to CV21.
Thank you for reply...
At the moment, i try to set up the transfer date before 8th of Oct.
Then it works fine.
It sounds very complicate that you explain the NLU procedure.
Not sure if i can fix it.
So i guess just leave the way it is not until the cash register broken again.
Very regret to buy casio 4000f.
Maybe i should buy better one next time.
Thank you C-Tech
