Guard Bar (Interleaved 2 of 5)
Note: Whenever Guard Bar is enabled, the presence of guard bars is required for decoding
to take place.
Usage: Useful when I 2 of 5 multisymbols are enabled to prevent false data out-
put. This typically occurs with highly tilted or skewed symbols.
Definition: A guard bar is a heavy bar, at least 2 times the width of the wide bar, surrounding
the printed I 2 of 5 symbol and helping to prevent false reads.

Range Mode (Interleaved 2 of 5)
Note: Whenever Guard Bar is enabled, the presence of guard bars is required for decoding
to take place.
Definition: When enabled, this feature causes symbol length # 1 and symbol length # 2
to form of a range of lengths that can be decoded.
For example, if symbol lengths of 10 and 6 are enabled, those are the
lengths that can be decoded. Note that either length can serve as the minimum
or maximum.
