IMPORTANT NOTES
Additional Precautions
551
• Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of loosing important data, we recommend that
you periodically save a backup copy of important data
you have stored in the unit’s memory on a USB memory
or floppy disk.
552
• Unfortunately, it may be impossible to restore the contents
of data that was stored in the unit‘s memory, on a USB
memory, or on a floppy disk once it has been lost. Roland
Corporation assumes no liability concerning such loss of
data.
553
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
554
• Never strike or apply strong pressure to the display.
556
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
557
• A small amount of heat will radiate from the unit during
normal operation.
558a
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
559b
• When you need to transport the unit, pack it in shock-
absorbent material. Transporting the unit without doing
so can cause it to become scratched or damaged, and
could lead to malfunction.
560
• Do not apply undue force to the music stand while it is in
use.
562
• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this unit.
The use of such cables can cause the sound level to be
extremely low, or impossible to hear. For information on
cable specifications, contact the manufacturer of the cable.
565
• Before opening or closing the keyboard lid, always make
sure that no pets or other small animals are located on top
of the instrument (in particular, they should be kept away
from the keyboard and its lid). Otherwise, due to the
structural design of this instrument, small pets or other
animals could end up getting trapped inside it. If such a
situation is encountered, you must immediately switch off
the power and disconnect the power cord from the outlet.
You should then consult with the retailer from whom the
instrument was purchased, or contact the nearest Roland
Service Center.
Handling Floppy Disks
(Using Optional Floppy Disk Drive)
651
• Floppy disks contain a plastic disk with a thin coating of
magnetic storage medium. Microscopic precision is
required to enable storage of large amounts of data on
such a small surface area. To preserve their integrity,
please observe the following when handling Floppy disks:
• Never touch the magnetic medium inside the disk.
• Do not use or store Floppy disks in dirty or dusty areas.
• Do not subject Floppy disks to temperature extremes
(e.g., direct sunlight in an enclosed vehicle). Recom-
mended temperature range: 10 to 50˚C (50 to 122˚F).
• Do not expose Floppy disks to strong magnetic fields,
such as those generated by loudspeakers.
652
• Floppy disks have a “write protect” tab which can protect
the disk from accidental erasure. It is recommended that
the tab be kept in the PROTECT position, and moved to
the WRITE position only when you wish to write new
data onto the disk.

653
• The identification label should be firmly affixed to the
disk. Should the label come loose while the disk is in the
drive, it may be difficult to remove the disk.
654
• Store all disks in a safe place to avoid damaging them, and
to protect them from dust, dirt, and other hazards. By
using a dirty or dust-ridden disk, you risk damaging the
disk, as well as causing the disk drive to malfunction.
655
• Disks containing performance data for this unit should
always be locked (have their write protect tab slid to the
“Protect” position) before you insert them into the drive
on some other unit (except the PR-300, or a product in the
HP-G, MT, KR, or Atelier families), or into a computer’s
drive. Otherwise (if the write protect tab remains in the
“Write” position), when you perform any disk operations
using the other device’s disk drive (such as checking the
contents of the disk, or loading data), you risk rendering
the disk unreadable by this unit’s disk drive.
