Code 39 Fixed Length 1
This feature specifies Code 39 first fixed length.
To set this feature:
1. Scan the SWITCH bar code.
2. Scan the bar code, SET CODE 39 FIXED LENGTH 1 below.
You’ll need to cover any unused bar codes on this and the facing
page to ensure that the scanner reads only the bar code you intend
to scan.
3. Scan the appropriate digits from the keypad in Appendix C that
represent the desired fixed label length. The selectable range for
this option is 00 to 50. Pad all single digit numbers with a leading
zero to yield a two-digit entry (00-50).
4. Complete the programming sequence by scanning the SWITCH
bar code.
SET CODE 39 FIXED LENGTH 1
NOTE
This applies when Code 39 Length Control is set to fixed-length
decoding.
The minimum decodable length is four when an optional check character
is present.
