Next press and hold the Tune button on the reader to initiate the tuning sequence; this will take
about five seconds and you will see the illumination LED's begin to flash. In the tuning sequence the
following things will be accomplished.
Optimize focus (when liquid lens module is installed)
Optimize brightness
Test different exposures (both gain and exposure time)
Plot decode results on the graph
Automatically apply the optimum settings when finished
The graph may appear something like the one below (Fig. 16). The dots represent decodes at
different settings and the dots above the decoding threshold are good reads; those below are no
reads. Dots that are higher on the graph represent settings that provide more reliable decoding.
Click the Trigger icon in the menu bar (Fig. 17) to trigger a read, assuring that the good code can
indeed be read. Now cover all codes but one and trigger the reader again to insure that a different
code can be read. Repeat this until all of the codes on the card are read.
