Code 39 Settings
Code 39 Minimum and Maximum Length: This selection is used to set the valid reading length of the bar code. If the data length of
the scanned bar code doesn't match the valid reading length, the 3060/3080 will issue a long error beep. You may wish to set the
same value for minimum and maximum length to force the scanner to read fixed length bar code data. This helps reduce the
chances of a misread.
