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.)
Note: To adjust centering when the scanner is in the stand, see Presentation Centering (page
If a bar code is not touched by a predefined window, it will not be decoded or output by the scanner. If centering is turned on by scanning Centering On, the scanner only reads codes that pass through the centering window you specify using the Top of Centering Window, Bottom of Centering Window, Left, and Right of 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.
