Special Considerations
When scanning codes on a low contrast substrate like
corrugated material or a specular substrate (such as
shiny aluminum or plastic material), a scan angle other
than 30 degrees may produce better decoding charac-
teristics. Contact RJS Technical support if scanning
problems occur.
