Depending on the selected barcode protocol, the data may not be displayed.
("Invalid" or "Incorrect check digit" appears.)
If the barcode cannot be displayed, any of the following may be the cause.
- Data that cannot be used with that bar code is included.
- The data does not include the specified number of digits.
- The check digit calculation is incorrect.
Check the data or change the bar code protocol, e.g "CODE39" or "CODE128" can be used.
