4.6.2.2 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 sensitive. Default = 1.
Sensitivity
4.6.2.3 Centering
Use Centering to narrow the scan engine’s field of view to make sure that
when the scanner is hand-held, it reads only those bar codes intended by
the user. For instance, if multiple codes are placed closely together,
centering will insure that only the desired codes are read. (Centering can be
used in conjunction with Aimer Delay, for the most error-free operation in
applications where multiple codes are spaced closely together. Using the
Aimer Delay and Centering features, the scanner can emulate the operation
of older systems, such as linear laser bar code scanners.)If a bar code is not
touched by a predefined window, it will not be decoded or output by the scan
engine. If centering is turned on by scanning Centering On, the scan engine
only reads codes that pass through the centering window you specify using
the Top of Centering Window and Bottom of Centering Window bar codes.
