Reading Techniques
The imager has a bright red aiming beam that corresponds to its horizontal field 
of view.  The aiming beam should be centered horizontally over the bar code; it 
will not read if the aiming beam is in any other direction. 
 
The best focus point for reading most code densities is about 5 inches (12.7 
cm) from the unit.  To read a single bar code or multiple bar codes (on a page or 
on an object), hold the imager at an appropriate distance from the target, pull 
the trigger, and center the aiming beam on the bar code.
Reading PDF417 Bar Codes
Note: Applies to 3800gHD and 3800gPDF.
To read PDF417 bar codes with a PDF-enabled 3800gHD/3800gPDF, hold the 
trigger down and move the scanner up and down so the aiming line sweeps 
from the top of the bar code to the bottom, and back up.  This ensures that the 
entire code is scanned.
