UPC/EAN Security Level
The Phaser offers four levels of decode security for UPC/EAN bar codes. Increasing levels
of security are provided for decreasing levels of bar code quality. There is an inverse
relationship between security and scanner aggressiveness, so be sure to choose only that
level of security necessary for any given application.
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 decoding “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
before others (i.e., 1, 2, 7, 8). If you are experiencing mis-decodes of poorly printed bar
codes, and the mis-decodes are limited to these characters, select this security level.
UPC/EAN SECURITY LEVEL 1
UPC/EAN Security Level 2
If you are experiencing mis-decodes of poorly printed bar codes, and the mis-decodes are
not limited to characters 1, 2, 7, and 8, select this security level.
