You scan a valid bar code label to enter
data for your application. The data
decoded by the scan module does not
match the data encoded in the bar code
label.
The computer may have decoded the bar code label in
a symbology other than the label’s actual symbology.
Try scanning the bar code label again. Make sure you
scan the entire label.
