If you click on the link that says Advanced Training Settings the Symbology Settings dialog will open
with the Training tab selected. At the bottom of this dialog is a button to undo the code training. You
can also just click the Untrain Code button at the left side of the Tune menu (Fig. 25 on previous
page). Additionally you can select the Actions menu in the ribbon and click the hotkey to Untrain
Code (Fig. 26). Additionally hovering your mouse over this button provides the same
information seen when hovering over the Advanced Training Settings. Removing the trained
information about the code will take a couple of seconds. Regardless of which method you use to
undo the training, each button will change to show Train Code.

Now place the Ace of Diamonds in the field of view and trigger the reader. Was the code read? Try
the Two of Diamonds. Can you read that code? Click on each of the links in the Tune menu to see
which dialogs open up. Can you figure out another way to open the same dialogs? The Quick
Setup pane and the menu items of the buttons appearing there are designed to allow you to
quickly find the more common settings you need configure the reader.
Conclusion:
You have learned about using the Quick Setup pane, tuning the reader and what it means to train a
code. Sometimes training a code is very useful as it typically decreases the time taken to read a
code; the reader will only look for specific code properties and reject all others meaning that
searching for the code is streamlined. Sometimes it is not useful as codes may change, either in
symbology, orientation (for 1D codes) or length.
Just as you were able to read multiple codes in the field of view you can also train on multiple codes
in a field of view. This is accomplished in the Symbology Settings dialog on the Multicode and
Training tabs and the Train Code hotkey in the Actions menu.
