Due to the construction of the D 2 of 5 symbology, it is possible for a scan line covering only a
portion of the code to be interpreted as a complete scan, yielding less data than is encoded in the
bar code. To prevent this, select specific lengths (D 2 of 5 - One Discrete Length - Two Discrete
Lengths) for D 2 of 5 applications.
