IMPORTANT NOTES

291b

In addition to the items listed under “IMPORTANT
SAFETY INSTRUCTIONS” and “USING THE UNIT
SAFELY” on pages 2–7, please read and observe the
following:

Power Supply

301

• Do not connect this unit to same electrical outlet that is
being used by an electrical appliance that is controlled by
an inverter (such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that contains a
motor. Depending on the way in which the electrical
appliance is used, power supply noise may cause this unit
to malfunction or may produce audible noise. If it is not
practical to use a separate electrical outlet, connect a
power supply noise filter between this unit and the
electrical outlet.

307

• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.

308

• Although the LCD and LEDs are switched off when the
POWER switch is switched off, this does not mean that the
unit has been completely disconnected from the source of
power. If you need to turn off the power completely, first
turn off the POWER switch, then unplug the power cord
from the power outlet. For this reason, the outlet into
which you choose to connect the power cord’s plug
should be one that is within easy reach and readily acces-
sible.

Placement

352a

• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.

352b

• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicinity of
this unit. Such noise could occur when receiving or initi-
ating a call, or while conversing. Should you experience
such problems, you should relocate such wireless devices
so they are at a greater distance from this unit, or switch
them off.

353

• Observe the following when using the unit’s floppy disk
drive. For further details, refer to
Before Using Floppy
Disks
(p. 6)..
• Do not place the unit near devices that produce a
strong magnetic field (e.g., loudspeakers).
• Install the unit on a solid, level surface.
• Do not move the unit or subject it to vibration while
the drive is operating.

354a

• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.

355b

• When moved from one location to another where the
temperature and/or humidity is very different, water
droplets (condensation) may form inside the unit. Damage
or malfunction may result if you attempt to use the unit in
this condition. Therefore, before using the unit, you must
allow it to stand for several hours, until the condensation
has completely evaporated.

Maintenance

401a

• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.

402

• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.

Repairs and Data

452

• Please be aware that all data contained in the unit’s
memory may be lost when the unit is sent for repairs.
Important data should always be backed up on a
CD-R/RW disc, or written down on paper (when
possible). During repairs, due care is taken to avoid the
loss of data. However, 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

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 CD-R/RW
disc.

552

• Unfortunately, it may be impossible to restore the contents
of data that was stored on a CD-R/RW disc 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.
