If a bar code is not within the predefined window, it will not be decoded or output by the imager. If centering is turned on by scanning Centering On, the imager 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 Bottom and

Right.
