Important notes
291b
In addition to the items listed under “Important safety instructions” (p. 2) and “Using the unit safely” (p. 3), 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
accessible.
Placement
351
• Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum. To
alleviate the problem, change the orientation of this unit; or move
it farther away from the source of interference.
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 initiating 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.
354b
• 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. Also, do not allow lighting
devices that normally are used while their light source is very
close to the unit (such as a piano light), or powerful spotlights to
shine upon the same area of the unit for extended periods of time.
Excessive heat can deform or discolor the unit.
355b
• When moved from one location to another where the temper-
ature and/or humidity is very different, water droplets (conden-
sation) 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.
356
• Do not allow rubber, vinyl, or similar materials to remain on the
unit for long periods of time. Such objects can discolor or
otherwise harmfully affect the finish.
358
• Do not allow objects to remain on top of the keyboard. This can
be the cause of malfunction, such as keys ceasing to produce
sound.
359
• Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the exterior
finish.
Maintenance
401b
• To clean the unit, use a dry, soft cloth; or one that is slightly
dampened. Try to wipe the entire surface using an equal amount
of strength, moving the cloth along with the grain of the wood.
Rubbing too hard in the same area can damage the finish.
402
• Never use benzine, thinners, alcohol or solvents of any kind, to
avoid the possibility of discoloration and/or deformation.
403
• The pedals of this unit are made of brass.
Brass eventually darkens as the result of the natural oxidization
process. If the brass becomes tarnished, polish it using commer-
cially available metal polisher.
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 floppy disk, 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
• 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.
552
• Unfortunately, it may be impossible to restore the contents of
data that was stored 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 rest while it is in use.
561
• Use only the specified expression pedal (EV-7/5; sold separately).
By connecting any other expression pedals, you risk causing
malfunction and/or damage to the unit.
