Precautions
• Be sure to handle floppy disks and treat the disk drive with care. Follow
the important precautions below.
Compatible Disk Type
• 3.5" 2DD and 2HD type floppy disks can be used. A blank 2HD floppy disk
has been included with your instrument for you to record your performances.
Inserting/Ejecting Floppy Disks
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.
To eject a floppy disk:
• Before ejecting a floppy disk make sure
that the floppy disk drive is not in opera-
tion (the DISK IN USE indicator should
be off.)
• Press the eject button slowly as far as it
will go; the disk will automatically pop
out. When the disk is fully ejected, care-
fully remove it by hand.

Handling the Floppy Disk Drive(FDD) and Floppy Disk
• Never attempt to remove the disk or turn the power off during recording,
reading and playing back. Doing so can damage the disk and possibly the
disk drive.
• 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 millimeters. 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 partially ejected
disk, try pressing the eject button once again, or push the disk back into
the slot and then repeat the eject procedure.
• 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-available 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.
Never insert anything but floppy disks into the disk drive. Other
objects may cause damage to the disk drive or floppy disks.
