Symbol Technologies DS 3408 User Manual

13-35

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 I 2 of 5 to any length, one or two discrete lengths, or lengths within a specific range.

•

One Discrete Length - Select this option to decode only I 2 of 5 symbols containing a selected length. Select the length 
using the numeric bar codes in 

. For example, to decode only I 2 of 5 symbols with 14 

characters, scan I 2 of 5 - One Discrete Length, then scan 1 followed by 4. To correct an error or to change the 
selection, scan Cancel on page 

•

Two Discrete Lengths - Select this option to decode only I 2 of 5 symbols containing either of two selected lengths. 
Select lengths using the numeric bar codes in 

. For example, to decode only those I 2 of 5 

symbols containing either 2 or 14 characters, select I 2 of 5 - Two Discrete Lengths, then scan 0, 2, 1, and then 4. To 
correct an error or to change the selection, scan Cancel on page 

.

•

Length Within Range - Select this option to decode an I 2 of 5 symbol with a specific length range. Select lengths 
using numeric bar codes in 

For example, to decode I 2 of 5 symbols containing 

between 4 and 12 characters, first scan I 2 of 5 - Length Within Range. Then scan 0, 4, 1, and 2 (single digit numbers must 
always be preceded by a leading zero). To correct an error or change the selection, scan Cancel on page 

.

•

Any Length - Scan this option to decode I 2 of 5 symbols containing any number of characters within the digital scanner 
capability. 

Due to the construction of the I 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 (I 2 of 5 - One Discrete Length - Two Discrete Lengths) for I 2 of 5 applications.
