Backup Configuration
You may save your customized Main Menu buttons (created with the “Altering the Main Menu”
feature) and Custom test patterns on a floppy disk. This function protects the information in
case of a hard disk problem. See Section 9: “To Backup Configurations”.
Restore Configuration
This function allows you to restore the information that was saved using the BACKUP
CONFIGURATION button. See Section 9: “To Restore Configurations” for details.
Caution: Restoring from a floppy disk will change the original Main Menu configu-
ration. It also replaces all custom tests in the Custom and Kinetic test libraries.
Cleanup Hard Disk Database
This feature deletes files containing patient data with no associated test data. This can occur
when patient data is entered, but the test is not saved. This can also happen when patient data
is entered early in the day for convenience, but the patient does not take the visual field test.
Pressing the CLEANUP HARD DISK DATABASE button will remove all the “unassociated” data
from the database. See Section 9: “Cleanup Hard Disk Database” to utilize this feature.
Rebuild Hard Disk Database
The rebuild function is used in the event of a database failure. Rebuilding the patient database
may take several hours to complete, depending upon the number of files present. It is best to
perform this function at the end of a day or over a weekend. See Section 9: “Rebuild Hard Disk
Database” for more information.
Rebuild Floppy Database
This allows the user to rebuild the database on a floppy disk. A full floppy disk may take
several minutes to rebuild. See Section 9: “Rebuild Floppy Disk Database” for details.
Install Software
This feature allows supplemental software to be loaded on the HFA II without requiring the
instrument to be turned off and on (rebooted). See the Appendix: “Installing New HFA II
Software” for details.
Diagnostics
This feature is only accessed by Carl Zeiss Meditec Engineers. It leads to a variety of tests used
for system calibration and repair.
Return to System Setup
This button returns you to the main System Setup screen.
