Triggered Presentation Mode
This mode uses light to detect the presence of an object. Default = Ambient and
Scanner Light.
Presentation LED Behavior after Decode
When a scanner is in presentation mode, the LED aimer dims 30 seconds after a
barcode is decoded. If you wish to dim the LED aimer immediately after a barcode
is decoded, scan the LEDs Off barcode, below. Default = LEDs On.
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 insure that only the desired codes are read.
Note: To adjust centering when the scanner is hand-held, see Centering (page 100).
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.
In the example below, the white box is the centering window. The centering window
has been set to 20% left, 30% right, 8% top, and 25% bottom. Since Barcode 1
passes through the centering window, it will be read. Barcode 2 does not pass
through the centering window, so it will not be read.
