PDF Learn Mode
This setting tells the scanner to brighten the LED’s when you have an optimal
distance between the scanner and the PDF417 code you are attempting to read.
Because some PDF417 codes are more compact than others, the reading
distance varies from code to code. When you turn on the PDF Learn Mode, the
IT3800/3900’s light becomes very bright when you are at the best distance for
reading the PDF417 code. Default = Off.
