Introduction
Manual Conventions
The conventions used in this manual to illustrate instrument keys and display
information are as follows:
MENU
This is an example of a hardkey. They are located below the display in the handle of
ProBER 2 and give access to different sets of instrument settings. The key shown
here accesses the main menu of the instrument and returns the cursor to the top of
the display.
This is an example of a softkey. They are located immediately below the display and
Tx + Rx
are used to select instrument settings. The functions associated with softkeys are
shown in the display directly above the softkey and change as you move the display
cursor from one instrument setting to another.
These are the cursor control keys. They are located in the handle and are used to
move the display cursor from one instrument setting to another.
