THE MAIN MENU
SCREEN
When the HFA II is turned on, the first screen displayed, after the start-up sequence, is the
Main Menu screen. Its primary functions are to display a series of test buttons (from which you
initiate the testing procedure), allow recall of the last test performed, and provide access to the
System Setup screen. A further explanation of Main Menu functions follows Figure 2.6 below.

Command buttons
A Test Button
Each test button displays the name of a test. Pressing the test button allows you to choose the
eye to be tested. See Section 3: “Using Test Buttons” for more information.
Recall Last Test
This button accesses the results from the last right and left eye tests performed. When the
HFA II is first powered on, this button appears ghosted. It will remain inaccessible until a test
has been run. The memory is cleared when the instrument is turned off.
Show Test Library
This button leads to a list of all available test patterns, including Screening, Threshold,
Specialty, Custom, and Kinetic tests. When you want to select a test not found on the Main Menu
screen, choose the SHOW TEST LIBRARY button. See Section 3: “The Test Library” for details.
The Main Menu test buttons may be customized to reflect your needs. Any test in the Test
Library may be placed on the Main Menu screen. Buttons which are not used very often may be
removed. A second line of text can be added to test buttons to differentiate tests with the same
name but having different parameters. See “Altering the Main Menu Screen” for additional
information.
