Training Feedback
The second LED from left on the reader 
glows green to indicate that it is currently 
trained, or yellow to indicate that it is not 
trained. 
Connect the reader to the Setup Tool to 
untrain it and allow it to recognize other 
enabled symbologies.
Incremental Training for Multiple Symbologies
If you want to train the reader to recognize multiple symbologies, you can 
present a single image showing all the desired symbologies and perform the 
training procedure previously described. 
If you cannot present a single image showing all the necessary symbologies, 
you can enable incremental training on the Training tab of the Symbology 
Settings pane: 
With incremental training enabled, you can train the reader using multiple 
images showing the symbologies you expect to decode. The reader will train 
each new symbology while retaining the existing trained symbologies.
