If you choose instead to set your own screen reader preferences, the following
guidelines can help you select options tailored to your specic needs.

Use the third screen to choose the reading order for documents that
are not tagged. e following options are supported:
Infer Reading Order From Document (Recommended). When this option is selected, Adobe •
Reader determines the reading order of untagged documents using an advanced method of layout
analysis. is option is recommended because it is most likely to provide the most accurate results.
It does, however, require more analysis and therefore may be slower than the other two options.
Le-To-Right, Top-To-Bottom Reading Order. When this option is selected, •
Adobe Reader interprets the reading order of untagged documents starting
from le to right on the page and moving from top to bottom.
Use Reading Order In Raw Print Stream. When this option is selected, Adobe Reader •
interprets the reading order of untagged documents based on the raw code in the
PDF document – essentially, the order text was recorded in the print stream.
When you choose either of the last two options, Adobe Reader does not include
form elds in the content, and it does not recognize tables.
Depending on the complexity of the PDF document, on-the-y tagging may not adequately
capture the intended reading order of the document. Many PDF documents have multiple
columns or complex page designs that can aect how well Adobe Reader interprets the
content. If you are having trouble reading a particular PDF document, you can experiment
with the various Reading Order options to see if one works better than the others.
e next control on this screen is a check box labeled “Override the Reading Order in Tagged Documents.”
While the Reading Order options above apply to untagged documents by default, this option causes Adobe
Reader to use the reading order you selected (instead of using the reading order specied by the tag structure)
for tagged documents as well. is option is useful if you receive PDF documents that are poorly tagged.
e nal control on this screen is a check box labeled “Conrm before Adding Tags to Document.” When
you select this option, Adobe Reader asks you to conrm its tagging options before it prepares an untagged
document for reading by your assistive technology. Tagging can be a time-consuming procedure, particularly
in larger documents, and this option alerts screen reader users when that procedure is about to begin.

On the next screen, there is a set of three radio buttons used to select the delivery method of pages
for assistive technology. When Adobe Reader delivers information to a screen reader, it loads
