using floppy diskettes. It also contains other basic informa-
tion about diskettes.
Floppy Diskette Handling Precautions
IMPORTANT!
¢ Keep diskettes away from televisions, stereos, and other
sources of magnetism. Magnetism can affect diskette con-
tents.
¢ Keep diskettes out of direct sunlight, and areas subjected
to high humidity and temperature extremes.
© Never try to take a diskette apart.
* Never apen the shutter of a diskette or touch the inside
with your fingers.
¢ Never bend a diskette or apply strong pressure to it.
° Make vou affix diskette labels only within the areas pro-
vided, and never affix a new label on top of an old one.
¢ Do not eject the diskette while the access lamp is lit or while
playback is in progress. Also, never tuen off power while a
diskette is loaded inside the FD-1. Doing so can corrupt
data on the diskette and cause malfunction of the FD-1.
® Never insert any other object besides the specified type of
diskette into the FD-1. Doing so can cause malfunction of
the FD-1.
* The FD-1 uses a magnetic head. A dirty head can make it
impossible to read data from a diskette or even corrupt dis-
kette contents. Use a commercially available cleaning dis-
kette to periodically clean the magnetic head.
* CASIO COMPUTER CO., LTD. assumes no responsi-
bility for the loss of any data stored on a floppy dis- ~
kette.

and 2DD (720KB formatted) diskettes. Use of other disk siz-
es and capacities is not supported.

the upper right corner of the front side, Also, there is
a square hole in the lower right corner.
2DD..... This type of diskette does not have a hole in the low-
er right corner.
Write Protection
You can write protect a diskette so data on it cannot be delet-
ed and no new data can be stored on the diskette.
IMPORTANT!
¢ Though you can read data from a diskette that is write pro-
tected (write protect hole open), you cannot store data on
it, delete its existing data, or format the diskette. Write pro-
tecting a diskette is a good way to protect important data
against accidental deletion.

Hole open

When the write protect hole is open as shown jn the illus-
tration, you can read the contents of the diskette, but you
cannot write data to or delete data from the diskette. After
saving important data to a diskette, be sure tu open its write
protect hole to protect the data against accidental changes
or deletion.
The diskette that comes with the FD-1 contains sample data
and so it is write protected.
