Security Level
The scanner offers four levels of decode security for delta bar codes, which include the Code 128 family,
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 default 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: Select this option if misdecodes occur. This security level should eliminate most
misdecodes.
• Security Level 2: Select this option if Security level 1 fails to eliminate misdecodes.
• Security Level 3: If Security Level 2 was selected 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 this level of security
is necessary, try to improve the quality of the bar codes.
