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.

Syntax Conventions
• The NSA may be referred to as the “NSA”, the “device” or the “system” in this
User’s Guide.
• Product labels, screen names, field labels and field choices are all in bold font.
• A key stroke is denoted by square brackets and uppercase text, for example,
[ENTER] means the “enter” or “return” key on your keyboard.
• “Enter” means for you to type one or more characters and then press the
[ENTER] key. “Select” or “choose” means for you to use one of the predefined
choices.
• A right angle bracket ( > ) within a screen name denotes a mouse click. For
example, Maintenance > Log > Log Setting means you first click
Maintenance in the navigation panel, then the Log sub menu and finally the
Log Setting tab to get to that screen.
• Units of measurement may denote the “metric” value or the “scientific” value.
For example, “k” for kilo may denote “1000” or “1024”, “M” for mega may
denote “1000000” or “1048576” and so on.
• “e.g.,” is a shorthand for “for instance”, and “i.e.,” means “that is” or “in other
words”.
