multiple codes are spaced closely together. Using the Aimer Delay and Center-
ing 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 3-7).
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 win-
dow 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.
