6. Remove the Destination disk when you see the confirmation message, “Floppy Successfully
Duplicated”. If the duplication fails, repeat Steps 1-4. If the duplication fails again, repeat
Steps 1-4 with a different Destination disk. Direct problems to Carl Zeiss Meditec Customer
Service. Duplication may also be done using any PC compatible computer with a floppy disk
drive.
CAUTION: Use only High Density (HD) 1.44 MB disks. Regular density (720 K) and
2.88 MB Super High Density (SHD) disks will not work with the HFA II-
i . You risk losing
data if you use anything except High Density floppy disks.
To Initialize a Floppy Disk:
You always must use formatted disks with your HFA II-
i
. The following procedure may be used on
new or previously formatted disks.
1. Start at the File Functions screen. Select DISK UTILITIES>INITIALIZE FLOPPY.
2. Connect a USB floppy disk drive to a USB port on the HFA II-
i
.
3. Insert a floppy disk into the USB floppy disk drive.
4. Select OK to proceed with the initialization or CANCEL to leave the disk intact and return to
the File Functions menu. If you select OK, the next screen displays, “Formatting disk”.
Remember that the INITIALIZE FLOPPY function permanently erases ALL information currently
stored on the floppy disk.
5. Remove the disk when you see the confirmation message, “Floppy Successfully Formatted”. If
the formatting fails, repeat steps 1-3.
CAUTION: INITIALIZE FLOPPY prepares the floppy disk to record information from the
HFA II-
i . All data previously stored on the disk will be erased during initialization.
Duplication and initialization of the floppy disk may also be done using any PC
compatible computer with a floppy disk drive. Use only High Density (HD) 1.44 MB
disks. Regular density (720 K) and Super High Density (2.88 MB) disks will not work
with the HFA II-
i .
To Compare Test Results:
The Compare feature analyzes the results of two threshold tests to show the change in threshold
values. Negative values indicate decreased sensitivity; positive values indicate increased sensitivity.
Tests must be from the same patient, the same eye, the same test type, and must be of the same test
pattern with one exception: 24-2 and 30-2 tests may be analyzed together. However, only the points
the patterns share in common will be compared. Tests must also be stored on the same source. You
may print the results of a COMPARE TESTS by pressing the
PRINT FUNCTIONS
icon. Compared test
results cannot be saved.
