Presentation Mode. Typically used when the digital scanner sits on a counter top or is mounted on a wall, in this mode,
the digital scanner operates in continuous (constant-on) mode, where it automatically decodes a bar code presented
in its field of view.
Print Contrast Signal (PCS). Measurement of the contrast (brightness difference) between the bars and spaces of a
symbol. A minimum PCS value is needed for a bar code symbol to be scannable. PCS = (RL - RD) / RL, where RL
is the reflectance factor of the background and RD the reflectance factor of the dark bars.
Programming Mode. The state in which a scanner is configured for parameter values. See Scanning Mode.
