• You need to program a suffix.  Programming a suffix enables the scanner 
to output the bar code data plus the key you need (such as “CR”) to enter 
the data into your application.  Refer to Prefix/Suffix Overview on page 4-
1 for further information.
Does the scanner read the bar code incorrectly?
If the scanner reads a bar code, but the data is not displayed correctly on 
the host screen:
• The scanner may not be programmed for the appropriate terminal 
interface. 
For example, you scan “12345” and the host displays “@es%.”
Reprogram the scanner with the correct Plug and Play bar code.  See 
Programming the Interface beginning on page 2-1.
• The scanner may not be programmed to output your bar code data 
properly.
For example, you scan “12345” and the host displays “A12345B.”
Reprogram the scanner with the proper symbology selections.  See 
Chapter 6.
The scanner won’t read your bar code at all.
1. Scan the sample bar codes in the back of this manual.  If the scanner 
reads the sample bar codes, check that your bar code is readable.
Verify that your bar code symbology is enabled (see Chapter 6).  
2. If the scanner still can’t read the sample bar codes, scan All 
Symbologies On, page 6-1.
If you aren’t sure what programming options have been set in the scanner, 
or if you want the factory default settings restored, refer to Setting Custom 
Defaults on page 1-5.
