3.4.5 Set Lengths for Code 39 
The length of a code refers to the number of characters (i.e., human 
readable characters), including check digit(s) the code contains. Set 
lengths for Code 39 to any length, one or two discrete lengths, or lengths 
within a specific range. If Code 39 Full ASCII is enabled, Length Within 
Range or Any Length are the preferred options. The default is Length 
Within Range: 2 to 55. 
 
Scan one of the following bar codes to select a length option: 
• One Discrete Length - Decode only Code 39 symbols containing a 
selected length. Select the length using the bar 
codes in Appendix B, Numeric Bar Codes. For 
example, to decode only Code 39 symbols with 
14 characters, scan Code 39 - One Discrete 
Length, and then scan 1, 4. To correct an error or 
change the selection, scan Cancel.  
• Two Discrete Lengths - Decode only Code 39 symbols containing either 
of two lengths. Select lengths using the bar 
codes in Appendix B, Numeric Bar Codes. For 
example, to decode only Code 39 symbols 
containing either 2 or 14 characters, scan Code 
39 - Two Discrete Lengths, and then scan 0, 2, 
1, 4. To correct an error or change the selection, 
scan Cancel. 
• Length Within Range - Decode Code 39 symbols with a specific length 
range. Select lengths using the bar codes in 
Appendix B, Numeric Bar Codes. For example, 
to decode Code 39 symbols containing between 
4 and 12 characters, scan Code 39 - Length 
Within Range, and then scan 0, 4, 1, 2. To 
correct an error or change the selection, scan 
Cancel. 
• Any Length - Decode Code 39 symbols containing any number of   
characters within the engine’s capability. 
Note : When setting lengths, enter a leading zero for single digit numbers.
