Important notes
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “Using the unit safely” (p. 2), please
read and observe the following:
Power Supply
• 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 pro-
duce audible noise. If it is not practical to use a separate elec-
trical outlet, connect a power supply noise filter between this
unit and the electrical outlet.
• 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.
• 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.
Placement
• 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.
• This device may interfere with radio and television reception.
Do not use this device in the vicinity of such receivers.
• 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.
• Do not expose the unit to direct sunlight, place it near devices
that radiate heat, leave it inside an enclosed vehicle, or other-
wise 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 pow-
erful spotlights to shine upon the same area of the unit for
extended periods of time. Excessive heat can deform or dis-
color the unit.
• When moved from one location to another where the temper-
ature and/or humidity is very different, water droplets (con-
densation) 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.
• 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.
• Do not allow objects to remain on top of the keyboard. This
can be the cause of malfunction, such as keys ceasing to pro-
duce sound.
• Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the exte-
rior finish.
Maintenance
• 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.
• Never use benzine, thinners, alcohol or solvents of any kind,
to avoid the possibility of discoloration and/or deformation.
• The pedals of this unit are made of brass.
Brass eventually darkens as the result of the natural oxidiza-
tion process. If the brass becomes tarnished, polish it using
commercially available metal polisher.
Additional Precautions
• Use a reasonable amount of care when using the unit’s but-
tons, sliders, or other controls; and when using its jacks and
connectors. Rough handling can lead to malfunctions.
• 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’s internal ele-
ments.
• A small amount of heat will radiate from the unit during nor-
mal operation.
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use head-
phones, so you do not need to be concerned about those
around you (especially when it is late at night).
• When you need to transport the unit, pack it in shock-absor-
bent material. Transporting the unit without doing so can
cause it to become scratched or damaged, and could lead to
malfunction.
• Do not apply undue force to the music rest while it is in use.
• Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the follow-
ing precautions.
• 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.
• Before opening or closing the keyboard lid, always make sure
that no pets or other small animals are located on top of the
instrument (in particular, they should be kept away from the
keyboard and its lid). Otherwise, due to the structural design
of this instrument, small pets or other animals could end up
getting trapped inside it. If such a situation is encountered,
you must immediately switch off the power and disconnect
the power cord from the outlet. You should then consult with
the retailer from whom the instrument was purchased, or
contact the nearest Roland Service Center.
