Security Level 2
Security Level 3
If Security Level 2 has been tried, and are still experiencing misdecodes, select this security level. Be advised, selecting this option
is an extreme measure against misdecoding severely out of spec bar codes. Selection of this level of security may significantly impair
the decoding ability of the scanner. If this level of security is necessary, try to improve the quality of the bar codes.
