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 lter between
this unit and the electrical outlet.
307
• Before connecting this unit to other devices, turn o 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 o when the POWER switch
is switched o, this does not mean that the unit has been completely
disconnected from the source of power. If you need to turn o the
power completely, rst turn o 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 ampliers (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
o.
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 dierent, 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.
361
• Do not put anything that contains water (e.g., ower 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

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 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 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 USB memories.
552
• Unfortunately, it may be impossible to restore the contents of data
that was stored in the unit’s memory, or USB memories 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.
555
• A small amount of noise may be heard from the display during normal
operation.
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.
558d edit
• The sound of keys being struck and vibrations produced by playing
an instrument can be transmitted through a oor or wall to an
unexpected extent.
In particular, when using headphones, please take care not to cause
annoyance to others nearby.
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 specied expression pedal (EV-5, EV-7; sold separately). By
connecting any other expression pedals, you risk causing malfunction
and/or damage to the unit.
