Important Notes
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.
304b
To prevent malfunction, switch off the piano’s power before you
install or replace the batteries in the included remote control unit.
306b
Batteries are supplied with the Remote Control. The life of these
batteries may be limited, however, since their primary purpose was to
enable testing.
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 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 conden-
sation 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.
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 an external memory, 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 an external memory.
552
Unfortunately, it may be impossible to restore the contents of data
that was stored in the unit’s memory or on an external 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 (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.
