Honeywell Xenon 1900 User Manual page 142

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.
Scan Centering On, then scan one of the following bar codes to change the
top, bottom, left, or right of the centering window. Then scan the percent you
want to shift the centering window using digits on the inside back cover of this
manual. Scan Save. Default Centering = 40% for Top and Left, 60% for Bot-
tom and Right.
