SYSTEM SETUP

REV. B 02/03 PN 51680-1
The System Setup screen is accessed by pressing the SYSTEM SETUP icon located on the Main
Menu screen. You may choose from a variety of selections on the two System Setup screens: the
main System Setup screen shown in Figure 2.7 and the Additional Setup screen illustrated in
Figure 2.8. Your selections will determine the mode in which your HFA II will power-up. An
explanation of the System Setup functions and procedures to alter the settings are described on
the following pages.

Language
The HFA II allows you to choose among English, German, Spanish, French, Italian, Japanese,
Portuguese, and Swedish languages. If you select a different language from the current
language set, the HFA II will automatically reboot in that language. The original language must
be re-selected in order to be reactivated.
Head Tracking (model 750i only)
When Head Tracking is turned ON, the instrument moves the chin rest during a test to keep the
patient's eye centered behind the trial lens holder. This action helps to reduce trial lens
artifacts (test points being blocked from the patient's view by the edge of the trial lens). This
feature only works if Gaze Tracking has been successfully initialized and the trial lens holder is
in the Up position. For more information see Section 5: "Head Tracking".
Vertex Monitor (model 750i only)
When the Vertex Monitor is turned ON, a beep is sounded and a message is displayed if the
patient's head is too far back from the trial lens during a test. This helps to eliminate the trial
lens as a source of visual field defects. This feature only works if Gaze Tracking has been
successfully initialized and the trial lens holder is in the Up position. For tips on using this
feature, see Section 5: "Vertex Monitor".
Set Time and Date
This allows you to reset the instrument's internal clock and calendar in a format appropriate
for your geographic region. Accurate date information is critical for correct STATPAC analysis,
age-corrected screening tests, and proper trial lens calculations.
