Warnings and Notes
These are how warnings and notes are shown in this User’s Guide.
Warnings tell you about things that could harm you or your device.
Note: Notes tell you other important information (for example, other things you may
need to configure or helpful tips) or recommendations.
The P-660R-F1 may be referred to as the “ZyXEL Device”, the “device”, the “system” or the
“product” in this User’s Guide.

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
in the navigation panel,
sub menu and finally the
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
“e.g.,” is a shorthand for “for instance”, and “i.e.,” means “that is” or “in other words”.
