UPC/EAN Security Level

The scanner offers four levels of decode security for UPC/EAN bar co des. Select higher levels of security for
decreasing levels of bar code quality. There is an inverse relationship b etween security and scanner decode
speed, so be sure to choose only that level of security n ecessary for any given application.
UPC/EAN Security Level 0
This is the default setting which allows the scanner to ope rate fastest, while providing sufficient security in
decoding “in-spec” UPC/EAN bar codes.
*UPC/EAN Security Level 0
UPC/EAN Security Level 1
As bar code quality levels diminish, certain characte rs become prone to misdecodes before others (i.e. , 1, 2, 7, 8).
If you are experiencing misdecodes of poorly printed bar c odes, and the misdecodes are limited to these
characters, select this security level.
UPC/EAN Security Level 1
UPC/EAN Security Level 2
If you are experiencing misdecodes of poorly printed bar c odes, and the misdecodes are not limited to characters
1, 2, 7, and 8, select this security level.
UPC/EAN Security Level 2
UPC/EAN Security Level 3
If you have tried Security Level 2, and still experience misdecodes, selec t this security level. Be advised, selecting
this option is an extreme measure against misdecoding s everely out of spec bar codes. Selecting this level of
security can significantly impair the scanner’s decoding ability. If this level of security is necessary, try to improve
the quality of your bar codes.
UPC/EAN Security Level 3
