Conventions Used in this Manual
The conventions used in this manual to illustrate instrument
keys and display information are as follows:
<Menu> This is an example of a hardkey. Hardkeys (located to the right
of the display) are used to give access to different sets of
instrument settings, or select dedicated instrument functions.
Menu Items Menu items appear in text as bold face with the greater than (>)
symbol separating each menu level. For example, if you are
instructed to choose Errors and Alarms from the Test Functions
menu item, it appears as Test Functions > Errors and Alarms.
Field Items Field items you are instructed to select in a window will appear
in bold face, for example select Signal Rate field.
Drop Down Lists The item you must select from a drop down list is also shown in
bold. For example, select Signal Rate field and choose STM-1 or
OC-3 from the drop down list.
