When the reader has been reset the image on the
Quick Setup pane will go back to being all white.
From the Quick Setup pane click on the arrow at the right side of the Tune button to open up the
pane with the tuning options (Fig. 23).
Tuning the reader can be accomplished from the software as well as the
Tune button on the reader.
From the software you can also customize how the system is tuned. At the top of the dialog are
options for what is performed in the tuning process. By default the code is trained when tuning is
performed. Training the code includes:

Training the symbology type

Training the number of pixels per module

For 1D codes, their orientation

For 2D codes, the grid size.
Codes with properties that differ from the trained properties will not be read. For the properties that
can have slight variations, there is some tolerance of the variation (orientation of 1D codes) before
the code is not read.
Enabling filter tuning allows the addition of image processing filters to be used in the decode
process; this can increase decode time so it may not be desirable in all situations. Exhaustive
tuning allows for a more thorough testing of possible light and exposure combinations to choose
something other than the first one that allows a decode.
