12 - 48 Symbol LS3408 Product Reference Guide
Security Level
The scanner offers four levels of decode security for UPC/EAN bar codes. Increasing levels of security are
provided for decreasing levels of bar code quality. There is an inverse relationship between security and scanner
decode speed, so be sure to choose only that level of security necessary for any given application.

Security Level 0

This is the default setting which allows the scanner to operate fastest, while providing sufficient security in
decoding "in-spec" UPC/EAN bar codes.

Security Level 1

As bar code quality levels diminish, certain characters become prone to misdecodes before others (i.e., 1, 2, 7, 8).
If the scanner is misdecoding poorly printed bar codes, and the misdecodes are limited to these characters, select
this security level.
