GENERAL
INFORMATION
Screen simplicity Almost every screen is divided into three areas: the Title Bar, the Screen Body, and the
Icon Buttons.
Figure 2.1: Main Areas of the HFA II Screen
The Title Bar
This area is the top portion of every screen. The middle of the title bar displays the name of the
screen in bold type. The left side shows the system software version and the
“i” button. More
information about the “ i ” button appears later in this section. The right side displays the
current date, time, and a picture that shows if the floppy disk in the drive is in use. Do not
insert or remove a floppy disk when the padlock is displayed on the screen as
shown above.
Operator messages may appear in the top right corner of the Title Bar or the center of the
Screen Body to inform you of a condition or alert you to a problem. “Printer is not connected
or Off Line” and “Uninitialized Disk” are examples of operator messages. Multiple messages
may appear stacked and overlapping in the upper right corner. Touching the top message
collapses it, revealing the previous message.
The Screen Body
The Screen Body comprises the largest part of every screen. This is where most of the com-
mands are issued via command buttons. The contents of the Screen Body changes after every
command. The Screen Body is referred to as the “screen” throughout the User’s Guide.
Frequently, a button will appear dimmed or “ghosted.” This indicates either that the button
function cannot be activated from that screen or that the button represents a feature that is not
available on the HFA II model being used. For example, the CUSTOM TESTS button on the
model 720i HFA II has been ghosted because this option is not available on the model 720i and
is, therefore, nonfunctional.
