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 for any length, one or two discrete lengths, or lengths within a specific 
range. If Code 39 Full ASCII is enabled, Length Within a Range or Any Length are the preferred options.
One Discrete Length - This option allows the digital scanner to decode only those Code 39 symbols containing a 
selected length. Use the numeric bar codes in 
 to select the length. For example, 
to decode only Code 39 symbols with 14 characters, scan Code 39 - One Discrete Length, then scan followed 
by 4. In case of an error, or to change the selection, scan Cancel on
Two Discrete Lengths - This option allows the digital scanner to decode only those Code 39 symbols 
containing either of two selected lengths. Use the numeric bar codes in 
 to select 
lengths. For example, to decode only Code 39 symbols containing either 2 or 14 characters, select Code 39 - Two 
Discrete Lengths
, then scan 02, 1, and then 4. In case of an error, or to change the selection, scan Cancel 
on
.
Length Within Range - This option allows the digital scanner to decode a Code 39 symbol within a specific 
length range. Use the numeric bar codes in 
 to select the length range
For 
example, to decode Code 39 symbols containing between 4 and 12 characters, first scan Code 39 - Length 
Within Range
. Then scan 041, and 2 (enter a leading zero for single digit numbers). In case of an error, or to 
change the selection, scan Cancel on
.
Any Length - This option allows the digital scanner to decode Code 39 symbols containing any number of 
characters within the digital scanner’s capability.
NOTE
When setting lengths for different bar code types, enter a leading zero for single digit numbers.
