Upc/Ean Security Level 2; Upc/Ean Security Level 3 - Symbol P 300STD Product Reference Manual

UPC/EAN Security Level 2

If you are experiencing misdecodes of poorly printed bar codes, and the misdecodes are not
limited to characters 1, 2, 7, and 8, select this security level.

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 spec bar codes, and security significantly impairs the decoding ability of the scanner. If this
level of security is necessary, try to improve the quality of your bar codes.
