IMPORTANT NOTES
Handling the Floppy Disk Drive
(Using Optional Floppy Disk Drive)
Never attempt to remove a floppy disk from the drive while the drive
is operating (the indicator is lit); damage could result to both the disk
and the drive.
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 (e.g., direct
sunlight in an enclosed vehicle). Recommended temperature
range: 10 to 50 degree C (50 to 122 degree F).
Do not expose floppy disks to strong magnetic fields, such as
those generated by loudspeakers.
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.
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.
Handling Using USB memory
(Using Optional USB memory)
Do not connect or disconnect USB memory while it is being read
from, or written to (i.e., while the USB memory access indicator will
blink).
Carefully insert the USB memory all the way in—until it is firmly in
place.
Never touch the External Memory connector. Also, avoid getting the
terminals dirty.
USB memories are constructed using precision components; handle
the USB memories carefully, paying particular note to the following.
To prevent damage to the USB memories from static electricity, be
sure to discharge any static electricity from your own body before
handling the USB memories.
Do not touch or allow metal to come into contact with the contact
portion of the USB memories.
Do not bend, drop, or subject USB memories to strong shock or
vibration.
Do not keep USB memories in direct sunlight, in closed vehicles,
or other such locations.
Do not allow USB memories to become wet.
Do not disassemble or modify the USB memories.
Handling CD-ROMs
(Using Optional CD-ROMs)
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.
