UPC/EAN Security Level 3
If you have tried Security Level 2, and are still experiencing misdecodes, select this security
level. Be advised, selecting this option is an extreme measure against misdecoding severely out

of the scanner. If this level of security is necessary, you should try to improve the quality of
your bar codes.
