Security Level
The Symbol  LS7708 offer four levels of decode security for the delta bar codes. These include the Code 128 family, UPC/EAN, Code 
93 and Scanlet. 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.
Security Level 0
This is the default setting. It allows the fastest scanner operation while providing minimum security for most “in-spec” bar codes. 
Some level of misdecodes is expected.
*
 Security Level 0
Security Level 1
This setting allows the optimum scanner speed that provides sufficient security in decoding most “in-spec” bar codes. This level 
should eliminate most misdecodes.
