Handling the ﬂoppy disk drive (FDD) and ﬂoppy disks

This instrument features a built-in ﬂoppy disk drive (on the front panel). It lets you save original data you’ve created on the

instrument to ﬂoppy disk, and allows you to load data from ﬂoppy disk to the instrument.

Be sure to handle ﬂoppy disks and treat the disk drive with care. Follow the important precautions below.

■ Floppy disk compatibility

3.5" 2DD and 2HD type ﬂoppy disks can be used.

■ Formatting a ﬂoppy disk

● If you ﬁnd that you are unable to use new, blank disks or old

disks that have been used with other devices, you may need

to format them. For details on how to format a disk, see page

59. Keep in mind that all data on the disk will be lost after for-

matting. Make sure to check beforehand whether or not the

disk contains important data.

• Floppy disks formatted on this device may or may not be useable as

is on other devices.

■ Inserting/removing Floppy Disks

● Inserting 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 power is turned on, the drive lamp (at the bottom left of

the drive) lights to indicate the drive can be used.

•Never insert anything but ﬂoppy disks into the disk drive. Other

objects may cause damage to the disk drive or ﬂoppy disks.

● Removing a ﬂoppy disk:

• After checking that the instrument is not accessing* the

ﬂoppy disk, ﬁrmly press the eject button at the lower right of

the disk slot all the way in.

When the ﬂoppy disk is ejected, pull it out of the drive. If the

ﬂoppy disk cannot be removed because it is stuck, do not

try to force it, but instead try pressing the eject button

again, or try re-inserting the disk and attempt to eject it

again.

* Access of the disk indicates an active operation, such as record-

ing, playback, or deletion of data. If a ﬂoppy disk is inserted while

the power is on, the disk is automatically accessed, since the

instrument checks whether the disk has data.

• Do not remove the ﬂoppy disk or turn off the instrument itself

while the disk is being accessed. Doing so may result not only in

loss of data on the disk but also damage to the ﬂoppy disk drive.

Be sure to remove the ﬂoppy disk from the disk drive before turn-

ing off the power. A ﬂoppy disk left in the drive for extended peri-

ods can easily pick up dust and dirt that can cause data-read and

-write errors.

■ Cleaning the disk drive read/write head

● 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 parti-

cles from the disks used that will eventually cause read and

write errors.

● To maintain the disk drive in optimum working order Yamaha

recommends that you use a commercially-available dry-type

head cleaning disk to clean the head about once a month.

Ask your Yamaha dealer about the availability of proper head-

cleaning disks.

■ About ﬂoppy disks

● Handle ﬂoppy disks with care, and follow these precautions:

• 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

produced by televisions, speakers, motors, etc., since mag-

netic ﬁelds can partially or completely erase data on the

disk, rendering 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.

● 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).

When saving data, make sure that the disk’s write-protect

tab is set to the “overwrite” position (tab closed).

● Data backup

•For maximum data security Yamaha recommends that you

keep two copies of important data on separate ﬂoppy disks.

This gives you a backup if one disk is lost or damaged.

NOTE

This lamp is always on when the power is on,

regardless of Disk operation.

This lamp lights during disk read/write operations, such as when a

disk has been inserted, during recording, playback, formatting, etc.

CAUTION
