7 DATABASE MANAGEMENT
The
File Functions (F4)
Screen provides database management capabilities. A single testing
database is used on the Matrix so all your visual field test results are available in the working
database.
DATABASE BACKUP
You can back up to the instrument’s testing database to removable media (floppy or CD-R). See
Figure (J). Back up your database regularly. Pick a backup schedule that fits your practice. Many
practices perform weekly backups to protect their patient visual field data.
To make a backup copy of the testing database to either floppy disk or CD-R:
1. Place either a floppy in the floppy drive or a CD-R in the CD-R/W drive.
2. Select the appropriate drive from the
Destination
pull down menu (click on the arrow).
3.
Select
the
Begin
Button.
Note
: Most CD-R disks are limited to about 48 separate writes; as a result, you can back up
almost a year’s worth of tests on a single CD-R media. It is also a good idea to alternate between
two CD-R media with each backup in case a problem develops with one of the media.
