USING DATA
DISKS
All HFA II models use 1.44 MB 3.5" high density floppy disks. Model 750i (optional on models
745i, 740i and 720i) also uses magneto-optical disks for storing patient data. To ensure the
integrity of the data, learn how to properly care for and handle these data disks.
Because data disks store information magnetically, the information can be destroyed by static
electricity and strong magnets. Typical sources of magnetic fields include telephones, fluores-
cent desk lamps, magnetic desk accessories and other electrical appliances.
• Keep your disks at least 5 feet from these sources of magnetic fields.
• Do NOT touch the recording surface of the disk.
• Remember to label data disks for easy identification. Be careful to not let the label
adhere to the sliding cover of the disk.
• Store data disks in their protective folders and in the original boxes supplied by the
manufacturer or in any filing system designed for the disks.
• Do NOT store data disks on top of the HFA II.
To insert a disk in the drive, first take it out of its protective case. Hold the disk so the arrow is
aimed at the drive and insert it completely into the drive.
To remove a disk from the drive, press the ejector button. Never remove the disk:
• When the indicator light is on.
• If the drive is running and the disk is moving.
• If the padlock is visible over the disk drive image in the upper-right corner of the
screen (see Figure 2.1).

Note: Use only 1.44 MB double-sided high density (HD) disks.
