If a bar code is not within the predefined window, it will not be decoded or output
by the scanner. If centering is turned on by scanning Centering On, the scan-
ner only reads codes that intersect the centering window you specify using the
Top, Bottom, Left, or Right bar codes.
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.
