In addition to the items listed under “IMPORTANT
SAFETY INSTRUCTIONS” and “USING THE UNIT
SAFELY”, please read and observe the following:
❏ Power supply
• Before connecting the KR-3 to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage .
• Do not use the KR-3 on the same power circuit with any
device that will generate line noise; an electric motor or
variable lighting system for example.
❏ Placement
• This instrument may interfere with radio and television
reception. Do not use this instrument in the vicinity of
such receivers.
• Do not place the instrument near devices that produce a
strong magnetic field (e.g., loudspeakers).
• Install the instrument on a solid, level surface.
• Do not move the instrument or subject it to vibration
while the disk drive is operating.
• Do not expose the KR-3 to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed vehi-
cle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.
❏ Maintenance
• For everyday cleaning wipe the instrument with a soft,
dry cloth or one that has been slightly dampened with
water. To remove stubborn dirt, use a mild, non-abrasive
detergent. Afterwards, be sure to wipe the instrument
thoroughly with a soft, dry cloth.
• Never use benzene, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
❏
Repairs and data backup
• Please be aware that data contained in the KR-3’s mem-
ory may be lost when the instrument is sent for repairs.
Important data should always be backed up on a floppy
disk, or written down on paper (if possible). During
repairs, due care is taken to avoid the loss of data. How-
ever, in certain cases (such as when circuitry related to
memory itself is out of order), we regret that it may not
be possible to restore the data, and Roland assumes no
liability concerning such loss of data.
❏ Additional precautions
• Please be aware that the contents of memory can be irre-
trievably lost as a result of a malfunction, or the improper
operation of the instrument. To protect yourself against
the risk of losing important data, we recommend that
you periodically save a backup copy of important data to
a high-quality floppy disk. Bear in mind, however, that it
may be impossible to restore the contents of data that was
stored on a floppy disk. Roland Corporation assumes no
liability concerning such loss of data.
• Use a reasonable amount of care when operating the
instrument’s buttons, sliders other controls. Rough han-
dling can lead to malfunctions.
• Never strike or apply strong pressure to the display.
• When connecting/disconnecting all cables, grasp the con-
nector itself—never pull on the cable. This way you will
avoid causing shorts, or damage to the cable wires.
• A small amount of heat will radiate from the instrument
during normal operation.
• To avoid disturbing your neighbors, try to keep the
instrument’s volume at a reasonable level. At times, it
may be preferable to use headphones.
• When you need to transport the KR-3, package it in the
box (including padding) that it came in or use a hard or
soft case.
Before using floppy disks
❏
Floppy disk drive
• Avoid using the KR-3 immediately after it has been
moved to a location with a significantly higher or lower
level of humidity. 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 instrument has been moved,
switch it on and wait at least one hour before using the
disk drive.
• 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.
• Never attempt to remove a floppy disk from the drive
while the drive is operating (the indicator is brightly lit);
damage could result to both the disk and the drive.
• Remove any disk from the drive before powering up or
down.
• 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.
❏
Handling floppy disks
• Floppy disks contain a plastic disk with a thin magnetic
coating. Microscopic precision is required to enable stor-
age 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.
