Important Notes

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

• Use a cable from Roland to make the connection. If using

some other make of connection cable, please note the
following precautions.

• 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 infor-
mation on cable specifications, contact the manufac-
turer of the cable.

Before Using Floppy Disks

Handling the Floppy Disk Drive

602

• Install the unit on a solid, level surface in an area free from

vibration.

603

• Avoid using the unit immediately after it has been moved

to a location with a level of humidity that is greatly
different than its former location. Rapid changes in the
environment can cause condensation to form inside the
drive, which will adversely affect the operation of the
drive and/or damage floppy disks. When the unit has
been moved, allow it to become accustomed to the new
environment (allow a few hours) before operating it.

604

• To insert a disk, push it gently but firmly into the drive—

it will click into place. To remove a disk, press the EJECT
button firmly. Do not use excessive force to remove a disk
which is lodged in the drive.

605a

• Never eject a disk while reading or writing is in progress,

since that can damage the magnetic surface of the disk,
rendering it unusable. (The disk drive’s indicator will
light up at full brightness when the drive is busy reading
or writing data. Ordinarily, the indicator will be less
brightly lit, or be extinguished.)

606

• Remove any disk from the drive before powering up or

down.

607

• To prevent damage to the disk drive’s heads, always try to

hold the floppy disk in a level position (not tilted in any
direction) while inserting it into the drive. Push it in
firmly, but gently. Never use excessive force.

608

• To avoid the risk of malfunction and/or damage, insert

only floppy disks into the disk drive. Never insert any
other type of disk. Avoid getting paper clips, coins, or any
other foreign objects inside the drive.

Handling Floppy Disks

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.
