{7} [A] < Data Safety Margin = 100%

{8} [A] < Horizontal Print Growth = +10% of X

{9} [A] < Vertical Print Growth = +12% of X

{1} is the Encoded Message.

{2} is the Banner heading.

{3} identifies the Symbology (DATA MATRIX) and lists the symbol's ECC and

size.

{4} lists the numbers of Data and Check Words, as well as the error correction

used.

{5} presents an approximate X-dimension.

Note: The reported X-dimension is approximate and based upon use of the

IT4410LR at 4.7 in (12 cm) (see "Reading Techniques" on page 1-1). If
you use different image engines, the X-dimension will vary. If you hold
the reader closer than 4.7 in (12 cm), it will have the effect of reporting a
larger than true X-dimension. Conversely, if you hold the reader farther
away than 4.7 in (12 cm), it will have the effect of reporting a smaller than
true X-dimension. Please contact HHP Application Support for additional
information. Refer to Chapter 3 for contact information.

{6} lists the number of Module Errors in the Fixed Patterns, which consist of

the Finder "L" and Clocking tracks around the perimeter of the symbol, their
adjacent quiet zones, and any interior alignment patterns in larger ECC200
symbols.

In Screening modes, this parameter is reported as "Too many Fixed Pattern
Errors (3)" when that is the case.

{7} lists the Data Safety Margin. This parameter is measured and reported

only for ECC200 symbols. These symbols have a fixed level of error correc-
tion. There is no equivalent parameter for the convolutional error encoding
used in older versions of Data Matrix. This parameter is just the "Unused
Error Correction" and always between 0 and 100%.

{8} and {9} list the Horizontal & Vertical Print Growths, respectively.
