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.
302
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a cause
for concern.
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.
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 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.
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.
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.
360
• Depending on the material and temperature of the surface
on which you place the unit, its rubber feet may discolor or
mar the surface.
You can place a piece of felt or cloth under the rubber feet
to prevent this from happening. If you do so, please make
sure that the unit will not slip or move accidentally.
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 defor-
mation.
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 USB
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 or on a USB memory.
552
• Unfortunately, it may be impossible to restore the contents
of data that was stored in the unit’s memory or on 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.
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).
559a
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
561
• Use only the specified expression pedal (EV-5; sold
separately). By connecting any other expression pedals,
you risk causing malfunction and/or damage to the unit.
