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

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
NOTE
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.
NOTE
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.

P-155 Owner's Manual
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).
