UPC/EAN Security Level

The LS 4800 offers four levels of decode secu-
rity for UPC/EAN bar codes. Increasing lev-
els of security are provided for decreasing
levels of bar code quality. There is an inverse
relationship between security and scanner ag-
gressiveness, so be sure to choose only that
level of security necessary for any given ap-
plication.
UPC/EAN Security Level 0
This is the default setting which allows the
scanner to operate in its most aggressive state,
while providing sufficient security in decod-
ing "in-spec" UPC/EAN bar codes.
UPC/EAN SECURITY LEVEL 0
UPC/EAN Security Level 1
As bar code quality levels diminish, certain
characters become prone to mis-decodes be-
fore others (i.e., 1, 2, 7, 8). If you are experienc-
ing mis-decodes of poorly printed bar codes,
and the mis-decodes are limited to these char-
acters, select this security level.
