Data in a Code 11 barcode may not include the checksum code. If there is, the
checksum code is the last one or two digit(s) of the data output. The checksum
code is the value added from all data collected, to check if the data is correct.
After you set the "Code 11 without Checksum" function, the scanner can recognize
all Code 11 barcodes normally. The scanner defaults the "Code 11 without
Checksum" setting.
