Insert the backup magneto-optical disk or first backup floppy disk, and select OK. A pop-
up window with the phrase “Restoring from magneto-optical/floppy” and a progress
indicator will appear. The HFA II is analyzing the disk to determine how long it will take to
merge the two databases.
5
When the analysis is
complete, a screen will
appear indicating the time it will
take to merge the two databases.
Press CONTINUE to complete the
merge procedure or press
CANCEL to stop it.
When the merge is complete, and the database integrity ensured, you will be returned to the
File Functions screen.
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.
In addition to removing extra patient data, this feature also acts as a hard disk utility by
reorganizing internal files and storage, thereby freeing up hard disk space. Some rearrange-
ment of the data structure will take place which may improve database access.
Caution: Some offices enter patient data (and trial lens information) but do not
save all test results. The next time the patient is tested, the patient data is still
available via the RECALL PATIENT DATA feature. Using the CLEANUP HARD DISK
DATABASE feature will remove this type of patient data information (not linked to
actual test results).
