Symbologies Length Within Range - This option allows you to decode an D 2 of 5 symbol with a specific length range. The length range is selected from numeric bar codes available in Chapter 8 of this guide. For example, to decode D 2 of 5 symbols containing between 4 and 12 characters, first scan D 2 of 5 - Length Within Range. Then scan 0, 4, 1, and 2 (single digit numbers must always be preceded by a leading zero). If you make an error or wish to change your selection, scan Cancel. D 2 of 5 - Length Within Range Any Length - Scanning this option allows you to decode D 2 of 5 symbols containing any number of characters within the scanner capability. ✎ 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 actually encoded in the bar code. To prevent this from happening, it is recommended that specific lengths (D 2 of 5- One Discrete Length - Two Discrete Lengths) be selected for D 2 of 5 applications.
