General Help for Accessing PDF Files

Portable Document Format (pdf) files can be seen on the screen (and printed) in the exact format created by the document developer.
Adobe (Acrobat) Reader, free software available for Windows, Macintosh, and UNIX systems, is required to read pdf files.
If you have not already installed the Adobe (Acrobat) Reader software, you will need to download the most current version appropriate for your computer system from the Adobe website. The Adobe (Acrobat) Reader is freely available to the public and may be redistributed.
On most browsers, the Adobe (Acrobat) Reader can be configured as a Plug-in or Helper Application that will directly open pdf files for viewing and/or printing. However, often the most convenient way to use large pdf files is to download them to your hard disk and open them separately with the Adobe (Acrobat) Reader.

Disable the Internet Explorer Pop-up Blocker

With Windows Service Pack 2, Internet Explorer 6 is configured by default to block pop-up windows from most websites. While many people appreciate this feature, others would rather not have Internet Explorer 6 automatically block these webpages.
To consult the PDF Bulletins you must disable pop-up blocking:
1. From Internet Explorer 6, Click "Tools".
2. Select "Pop-Up Blocker".
3. Select "Turn off Pop-up Blocker".
