What is PDF?
PDF is the abbreviation of Portable Document Format, and is a special format for viewing and printing
documents which have been downloaded from the Web.Why use PDF?
The Portable Document Format preserves the formatting of most documents better than alternatives like HTML
and MS Word.What do I need?
In order to view PDF documents, you need Adobe's Acrobat reader plugin. If you do not have this installed
on your machine, you may obtain it from http://www.adobe.com/products/acrobat/readstep.html.How do I know whether or not I have the PDF reader plugin?
The easiest way to find out whether or not you have the PDF reader plugin is to try and download a PDF; if
you have the plugin the document will open once the download is complete.What features does the PDF reader offer to help me navigate a document?
PDFs are displayed in two 'panes' (a window divided into two). The right hand pane contains the actual
document whilst the left pane contains the document index. This offers shortcuts to headings and
sub-headings within the document. The document can also be scrolled using the mouse, or pulled when the hand
tool is available.How can I view a PDF document more easily if I have difficulty with discerning variations
in colour, contrast or have low visual acuity?
The best solution is to set the accessibility preferences to allow high contrast viewing in your Acrobat
reader. The Acrobat 5.0 reader is the only version presently to support this facility.

Adobe have a web site which provides online tools to help visually disabled users whose screen reader
software is not compatible with the Adobe Acrobat Reader 5.0. These tools convert Adobe PDF documents into
HTML or ASCII text which can then be read by a number of common screen reading programs that synthesize text
as audible speech. This site - http://access.adobe.com/
- has a lot more information about accessibility.What are the minimum system requirements for Acrobat Reader 5.0?
- Intel® Pentium® processor Microsoft®
- Windows® 95 OSR 2.0, Windows 98 SE, Windows Millennium, Windows NT® 4.0 with Service Pack 5, or
Windows 2000
- 64 MB of RAM
- 24 MB of available hard-disk space
- Additional 70 MB of hard-disk space for Asian fonts (optional)
