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 modified
• Although the screen and indicators 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 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.
356
• Do not allow rubber, vinyl, or similar materials to remain on this
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.
361
• Do not put anything that contains water (e.g., flower vases) on this
unit. Also, avoid the use of insecticides, perfumes, alcohol, nail polish,
spray cans, etc., near the unit. Swiftly wipe away any liquid that spills
on the unit using a dry, soft cloth.
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 commercially
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 USB memories, 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 USB memory.
552 modified
• Unfortunately, it may be impossible to restore the contents of data
that was stored in the unit’s memory or a USB memory 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.
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.
