Tips for Reading User’s Guides On-Screen
When reading a ZyXEL User’s Guide On-Screen, keep the following in mind:
• If you don’t already have the latest version of Adobe Reader, you can download
it from http://www.adobe.com.
• Use the PDF’s bookmarks to quickly navigate to the areas that interest you.
Adobe Reader’s bookmarks pane opens by default in all ZyXEL User’s Guide
PDFs.
• If you know the page number or know vaguely which page-range you want to
view, you can enter a number in the toolbar in Reader, then press [ENTER] to
jump directly to that page.
• Type [CTRL]+[F] to open the Adobe Reader search utility and enter a word or
phrase. This can help you quickly pinpoint the information you require. You can
also enter text directly into the toolbar in Reader.
• To quickly move around within a page, press the [SPACE] bar. This turns your
cursor into a “hand” with which you can grab the page and move it around freely
on your screen.
• Embedded hyperlinks are actually cross-references to related text. Click them to
jump to the corresponding section of the User’s Guide PDF.
