Disk Operations
Using the Floppy Disk Drive (FDD) and Floppy Disk
Be sure to handle floppy disks and treat the disk drive with
care. Follow the important precautions below.
I Compatible Disk Type
3.5" 2DD and 2HD type floppy disks can be used.
I Inserting/Ejecting Floppy Disks
G To insert a floppy disk into the disk drive:
• Hold the disk so that the label of the disk is facing upward
and the sliding shutter is facing forward, towards the disk slot.
Carefully insert the disk into the slot, slowly pushing it all the
way in until it clicks into place and the eject button pops out.
• When the DGX-500/300 is turned on, the LED below the floppy
disk slot will be lit indicating that the Disk Drive is ready to use.
G To eject a floppy disk:
• Before ejecting the disk, be sure to confirm that the FDD is
stopped. Press the eject button slowly as far as it will go; the
disk will automatically pop out. When the disk is fully ejected,
carefully remove it by hand.
This lamp lights during disk read/write operations,
such as when a disk has been inserted, during
recording, playback, formatting, etc.
This lamp is always on when the power is on,
regardless of Disk operation.
• If the eject button is pressed too quickly, or if it is not pressed
in as far as it will go, the disk may not eject properly. The
eject button may become stuck in a half-pressed position
with the disk extending from the drive slot by only a few milli-
meters. If this happens, do not attempt to pull out the partially
ejected disk, since using force in this situation can damage
the disk drive mechanism or the floppy disk. To remove a par-
tially ejected disk, try pressing the eject button once again, or
push the disk back into the slot and then repeat the eject pro-
cedure.

G Never attempt to remove the disk or turn the power off dur-
ing recording, reading and playing back (when the DISK IN
USE lamp is lit). Doing so can damage the disk and possi-
bly the disk drive.
G Be sure to remove the floppy disk from the disk drive
before turning off the power. A floppy disk left in the drive
for extended periods can easily pick up dust and dirt that
can cause data read and write errors.
I Cleaning the Disk Drive Read/Write Head
G Clean the read/write head regularly. This instrument
employs a precision magnetic read/write head which, after
an extended period of use, will pick up a layer of magnetic
particles from the disks used that will eventually cause
read and write errors.
G To maintain the disk drive in optimum working order
Yamaha recommends that you use a commercially-avail-
able dry-type head cleaning disk to clean the head about
once a month. Ask your Yamaha dealer about the availabil-
ity of proper head-cleaning disks.
G Never insert anything but floppy disks into the disk drive.
Other objects may cause damage to the disk drive or
floppy disks.
I About the Floppy Disks
G To handle floppy disks with care:
• Do not place heavy objects on a disk or bend or apply pres-
sure to the disk in any way. Always keep floppy disks in their
protective cases when they are not in use.
• Do not expose the disk to direct sunlight, extremely high or
low temperatures, or excessive humidity, dust or liquids.
• Do not open the sliding shutter and touch the exposed sur-
face of the floppy disk inside.
• Do not expose the disk to magnetic fields, such as those pro-
duced by televisions, speakers, motors, etc., since magnetic
fields can partially or completely erase data on the disk, ren-
dering it unreadable.
• Never use a floppy disk with a deformed shutter or housing.
• Do not attach anything other than the provided labels to a
floppy disk. Also make sure that labels are attached in the
proper location.
G To protect your data (write-protect tab):
• To prevent accidental erasure of important data, slide the
disk's write-protect tab to the "protect" position (tab open).
Write protect tab ON
(locked or write pro-
tected)
Write protect tab OFF
(unlocked or write
enabled)
