symbols containing either of two selected lengths. Lengths are selected from

the numeric bar codes beginning on Appendix B. For example, to decode only

those Code 39 symbols containing either 2 or 14 characters, select Code 39 -

Two Discrete Lengths, then scan 0, 2, 1, and then 4. To change the selection

or cancel an incorrect entry, scan Cancel on Appendix B.

Length Within Range - This option limits decodes to only those Code 39

symbols within a specified range. For example, to decode Code 39 symbols

containing between 4 and 12 characters, first scan Code 39 - Length Within

change the selection or cancel an incorrect entry, scan Cancel on Appendix B.

Any Length - Scan this option to decode Code 39 symbols containing any
