Security Level 3
If the scanner is still misdecoding, 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 this level of security is necessary, try to improve the quality of the bar
codes.
Security Level 3
Bi-directional Redundancy
Use Bi-directional Redundancy for added 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.
