When Check Character is set to Validate and Transmit, the scanner only 
reads Plessey bar codes printed with a check character, and will transmit 
this character at the end of the scanned data.  
Default = No Check Charac-
ter.
Plessey Redundancy
If you are encountering errors when reading Plessey bar codes, you may 
want to adjust the redundancy count.  Redundancy adjusts the number of 
times a bar code is decoded before transmission, which may reduce the 
number of errors.  Note that the higher the redundancy count, the longer it 
will take to decode the bar code.  To adjust the redundancy, scan the 
Plessey Redundancy bar code below, then scan a redundancy count 
between 0 and 10 on the Programming Chart inside the back cover of this 
manual.  Then scan the Save bar code.  
Default = 0.
Plessey Message Length
Scan the bar codes below to change the message length.  Refer to 
Message Length Description (page 7-2) for additional information.  Mini-
mum and Maximum lengths = 1-80.   Minimum Default = 3, Maximum 
Default = 80.
