SYMBOLOGIES 8 - 73
Security Level
Parameter # 77
The scanner offers four levels of decode security for UPC/EAN and Code 93. Select increasing levels of
security for decreasing levels of bar code quality. There is an inverse relationship between security and
scanner aggressiveness, so choose only that level of security necessary for any given application.
• Security Level 0: This setting allows the scanner to operate in its most aggressive state, while providing
sufficient security in decoding most “in-spec” bar codes.
• Security Level 1: This default setting eliminates most misdecodes.
• Security Level 2: Select this option if Security level 1 fails to eliminate misdecodes.
• Security Level 3: If you selected Security Level 2 and misdecodes still occur, select this security level.
Be advised, selecting this option is an extreme measure against mis-decoding severely out of spec bar
codes. Selecting this level of security significantly impairs the decoding ability of the scanner. If you need
this level of security, try to improve the quality of the bar codes.
