All Symbologies
If you want to decode all the symbologies allowable for your scanner, scan the All 
Symbologies On code.  If on the other hand, you want to decode only a particular 
symbology, scan All Symbologies Off followed by the On symbol for that particular 
symbology.
Note: Scanner performance may reduce by scanning All Symbologies On. Only scan All 
Symbologies On when needed.  
Note: When All Symbologies On is scanned, 2D Postal Codes are not enabled.  2D Postal 
Codes must be enabled separately.
Message Length Description
You are able to set the valid reading length of some of the bar code symbologies.  
You may wish to set the same value for minimum and maximum length to force the 
scanner to read fixed length bar code data.  This helps reduce the chances of a 
misread.
EXAMPLE: Decode only those bar codes with a count of 9-20 characters.
Min. length = 09Max. length = 20
EXAMPLE: Decode only those bar codes with a count of 15 characters.
Min. length = 15Max. length = 15
For a value other than the minimum and maximum message length defaults, scan 
the bar codes included in the explanation of the symbology, then scan the digit 
value of the message length and Save bar codes on the  inside the back cover of 
this manual.  The minimum and maximum lengths and the defaults are included 
with the respective symbologies.
