38 N3680 Decoded Engine User Guide
Presentation Sensitivity
Presentation Sensitivity is a numeric range that increases or decreases the scan
engine's reaction time to bar code presentation. To set the sensitivity, scan the
Sensitivity bar code, then scan the degree of sensitivity (from 0-20) from the
inside back cover, and Save. 0 is the most sensitive setting, and 20 is the least sen-
sitive. Default = 1.
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 bar codes 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 3-46).
If a bar code 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 win-
dow you specify using the Top of Presentation Centering Window, Bottom of
Presentation Centering Window, Left, and Right of Presentation Centering Win-
dow bar codes.
