Presentation Sensitivity
Presentation Sensitivity is a numeric range that increases or decreases the
scanner's reaction time to barcode presentation. To set the sensitivity, scan the
Sensitivity barcode, then scan the degree of sensitivity (from 0-20) from the
Programming Chart, beginning on page 222, and Save. 0 is the most sensitive
setting, and 20 is the least sensitive. Default = 1.
Note: This command is not supported with the Gen 7 software revision. For infomation
about software revisions, see About Software Revisions on page 6.
Presentation Centering
Use Presentation Centering to narrow the scanner’s field of view when it is in
Presentation Mode 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 on page 51.
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.
