Linear Code Type Security Level (Redundancy Level)
Use this parameter to determine the security level appropriate for bar code quality. The security level indicates how many
times the bar code must be successfully read by the scanner before being decoded.
There are four security levels. Higher security levels are selected for decreasing levels of bar code quality. As security lev-
els increase, the scanner’s aggressiveness decreases.
Select an option by scanning one of the bar codes shown below. If you wish to change your selection, scan Cancel.
Note: Linear Code Type Security does not apply to Code 128.
