Using the Floppy Disk Drive (FDD) and Floppy Disks
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.
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.
• When the PSR-9000 is turned on, the LED below the floppy disk
slot will be lit indicating that the Disk Drive is ready to use.
To eject a floppy disk:
• Before ejecting the disk, be sure to confirm that the FDD is
stopped (check if the DISK IN USE lamp is off). 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 is always on
when the power is on,
regardless of the disk oper-
ation.
• 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.
Never attempt to remove the disk or turn the power off dur-
ing recording, reading and playing back. Doing so can dam-
age the disk and possibly the disk drive.
WARNING
• Before beginning installation, switch off the power to the PSR-9000 and con-
nected peripherals, and unplug them from the power outlet. Then remove all
cables connecting the PSR-9000 to other devices. (Leaving the power cord
connected while working can result in electric shock. Leaving other cables
connected can interfere with work.)
• Do not disassemble, modify, or apply excessive force to board areas and
connectors on hard disk, and SIMMs. Bending or tampering with boards and
connectors may lead to electric shock, fire, or equipment failures.
CAUTION
• Before handling the internal hard disk or SIMMs, you should briefly touch
DISK IN USE
DISK IN USE
This lamp lights during disk read/write
operations, such as when a disk has
been inserted, during recording, play-
back, formatting, etc.
Handling and Installation of Options
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 par-
ticles 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.
Never insert anything but floppy disks into the disk drive.
Other objects may cause damage to the disk drive or floppy
disks.
About the Floppy Disks
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 surface
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.
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)
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.
the metal surface to which the hard-disk or SIMM cover is attached (or other
such metallic area — be careful of any sharp edges) with your bare hand so
as to drain off any static charge from your body. Note that even a slight
amount of electrostatic discharge may cause damage to these components.
• It is recommended that you wear gloves to protect your hands from metallic
projections on the PSR-9000 hard disk, SIMMs, and other components.
Touching leads or connectors with bare hands may cause finger cuts, and
may also result in poor electrical contact or electrostatic damage.
• Take care to avoid dropping screws into the PSR-9000 unit. If a screw does
fall in, be sure to remove it before replacing the cover and powering up the
unit. Starting the unit with a loose screw inside may lead to improper opera-
tion or equipment failure. (If you are unable to retrieve a dropped screw, con-
sult your Yamaha dealer for advice.)
