Handling the Floppy Disk Drive (FDD) and Floppy Disks (Optional)

An optional ﬂoppy disk drive can be installed to this

instrument.

The ﬂoppy disk drive 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 pages 35. Keep in mind that all data on the disk will be

lost after formatting. 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 but-

ton pops out.

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 (checking that the use lamp on the ﬂoppy disk

drive is off), ﬁrmly press the eject button at the upper

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 play-

back 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.

CAUTION

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 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.

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 particles 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-avail-

able dry-type head cleaning disk to clean the head about

once a month. Ask your Yamaha dealer about the avail-

ability 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

pressure 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

surface of the ﬂoppy disk inside.

•Do not expose the disk to magnetic ﬁelds, such as those

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

magnetic 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).
