HF680 Series User Guide 35
Presentation Mode
Presentation Mode uses ambient light to detect barcodes. The LED dims until a
barcode is presented to the scanner, then the LED brightens to read the code. If the
light level in the room is not high enough, Presentation Mode may not work
properly.
Scan the following barcode to program your scanner for Presentation Mode.
Presentation Centering
Use Presentation Centering to narrow the scanner’s field of view when it is in the
stand to make sure the scanner reads only those barcodes intended by the user.
For instance, if multiple codes are placed closely together, Presentation Centering
will ensure that only the desired codes are read.
If a barcode is not touched by a predefined window, it will not be decoded or output
by the scanner. If Presentation Centering is turned on by scanning Presentation
Centering On, the scanner only reads codes that pass through the centering
window you specify using the Top of Presentation Centering Window, Bottom of
Presentation Centering Window, Left, and Right of Presentation Centering
Window barcodes.
