Presentation Sensitivity
Presentation Sensitivity is a numeric range that increases or decreases the scanner's reaction time to bar code presenta-
tion. 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 sensitive. Default = 1.
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 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 3-14).
If a bar code is not touched by a predefined window, it will not be decoded or output by the scanner. If Presentation Center-
ing 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 bar codes.
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 Bar Code 1 passes through the centering window, it will be read. Bar Code 2 does not
pass through the centering window, so it will not be read.
Note: A bar code needs only to be touched by the centering window in order to be read. It does not need to pass completely
through the centering window.
