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.
