92 Learning the Basics
Using PC Cards
❖Do not expose discs to direct sunlight or extreme heat or cold.
❖To clean a disc that is dirty, wipe it with a clean, dry cloth. The
most efficient method to clean it is to start from the center of
the disc and wipe toward the outward edge (not in a circle). If
necessary, moisten the cloth with water or a neutral cleaner
(not benzine or rubbing alcohol). Let the disc dry completely
before inserting it in the drive.
Using PC Cards
TECHNICAL NOTE: For PCMCIA-compatible PC Cards,
check the package to make sure they conform to the
PCMCIA 2.1 standard (or later). Other cards may work with
your computer, but are likely to be much more difficult to set
up and use.
For information on inserting or removing a PC Card, see
“Inserting and removing PC Cards” on page 155.

Hot swapping

With PC Cards, you can replace one PC Card with another while
the computer is on. This is called “hot swapping.”

Hot swapping precautions

Although you can insert a PC Card at any time, remember not to
remove a card while it is in use. Otherwise, you could lose
valuable information. For example:
❖Do not remove a hard disk card while the system is accessing
it.
❖Do not remove a network card while you are connected to a
network.
