Usage: Used when the leading and trailing edges of the symbols are smaller than
the standard margin or when other objects encroach into the margins.
Definition: Allows the scanner to read symbols with quiet zones less than 8 times the
width of the narrow bar element. The "quiet zone" is the space at the leading
and trailing ends of a symbol. Each quiet zone can be as narrow as only
five times the width of the narrow bar element when Narrow Margins is
