Security Level 2
If the scanner misdecodes poorly printed bar codes, and the misdecodes are not limited to characters 1, 2, 7, and
8, select this security level.
Security Level 3
If you selected Security Level 2, and the scanner still misdecodes, select this security level. Be advised, selecting
this option is an extreme measure against misdecoding severely out of spec bar codes. Selecting this level of
security can significantly impair the decoding ability of the scanner. If you need this level of security, try to improve
the quality of the bar codes.
Bi-directional Redundancy
Use Bi-directional Redundancy for additional security for linear code type security levels. When enabled, a bar
code must be successfully scanned in both directions (forward and reverse) before reporting a good decode.
