Important Notes
Handling Floppy Disks
651
• Floppy disks contain a plastic disk with a thin coating of
magnetic storage medium. Microscopic precision is
required to enable storage of large amounts of data on
such a small surface area. To preserve their integrity,
please observe the following when handling Floppy disks:
• Never touch the magnetic medium inside the disk.
• Do not use or store Floppy disks in dirty or dusty areas.
• Do not subject Floppy disks to temperature extremes
required to enable storage of large amounts of data on
such a small surface area. To preserve their integrity,
please observe the following when handling Floppy disks:
• Never touch the magnetic medium inside the disk.
• Do not use or store Floppy disks in dirty or dusty areas.
• Do not subject Floppy disks to temperature extremes
(e.g., direct sunlight in an enclosed vehicle). Recom-
mended temperature range: 10 to 50˚C (50 to 122˚F).
mended temperature range: 10 to 50˚C (50 to 122˚F).
• Do not expose Floppy disks to strong magnetic fields,
such as those generated by loudspeakers.
652
• Floppy disks have a “write protect” tab which can protect
the disk from accidental erasure. It is recommended that
the tab be kept in the PROTECT position, and moved to the
WRITE position only when you wish to write new data onto
the disk.

• The identification label should be firmly affixed to the disk.
Should the label come loose while the disk is in the drive, it
may be difficult to remove the disk.
may be difficult to remove the disk.
654
• Store all disks in a safe place to avoid damaging them,
and to protect them from dust, dirt, and other hazards. By
using a dirty or dust-ridden disk, you risk damaging the
disk, as well as causing the disk drive to malfunction.

• Carefully insert the USB memory all the way in—until it is
firmly in place.
705
• Never touch the terminals of the USB Memory. Also, avoid
getting the terminals dirty.
708
• USB Memory are constructed using precision components;
handle the cards carefully, paying particular note to the
following.

• To prevent damage to the cards from static electricity, be
sure to discharge any static electricity from your own body
before handling the cards.
before handling the cards.
• Do not touch or allow metal to come into contact with the
contact portion of the cards.
• Do not bend, drop, or subject cards to strong shock or vi-
bration.
• Do not keep cards in direct sunlight, in closed vehicles, or
other such locations (storage temperature: -25 to 85˚ C).
• Do not allow cards to become wet.
• Do not disassemble or modify the cards.

Handling CD-ROMs
801
• Avoid touching or scratching the shiny underside (encoded
surface) of the disc. Damaged or dirty CD-ROM discs may
not be read properly. Keep your discs clean using a
commercially available CD cleaner.
