Note: A barcode 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 Presentation Centering On, then scan one of the following barcodes to 
change the top, bottom, left, or right of the centering window. Then scan the 
percent you want to shift the centering window from the Programming Chart, 
beginning on page 133, then Save. Default Presentation Centering = 40% for Top 
and Left, 60% for Bottom and Right.
