IMPORTANT NOTES
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 or a motor
(such as a refrigerator, washing machine, microwave oven, or air
conditioner). 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.
• The AC adaptor will begin to generate heat after long hours of
consecutive use. This is normal, and is not a cause for concern.
• To prevent malfunction and equipment failure, always make sure
to turn off the power on all your equipment before you make any
connections.
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 otherwise subject
it to temperature extremes. Excessive heat can deform or discolor the
unit.
• 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.
• 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.
• 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.
• Do not put anything that contains water 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
• 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.
• Never use benzine, thinners, alcohol or solvents of any kind, to avoid
the possibility of discoloration and/or deformation.
Repairs and Data
• 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 flash drives, 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
• 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 flash drives.
• Unfortunately, it may be impossible to restore the contents of data that
was stored in the unit’s memory or USB flash drives once it has been
lost. Roland Corporation assumes no liability concerning such loss of
data.
• 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.
• Never strike or apply strong pressure to the display.
• When 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.
• To avoid disturbing others nearby, 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.
• The sound of keys being struck and vibrations produced by playing
an instrument can be transmitted through a floor or wall to an
unexpected extent. Please take care not to cause annoyance to others
nearby.
• 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.
• Do not apply undue force to the music rest while it is in use.
• Use only the specified expression pedal (EV-5, EV-7; sold separately). By
connecting any other expression pedals, you risk causing malfunction
and/or damage to the unit.
• 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.
• The explanations in this manual include illustrations that depict what
should typically be shown by the display.
Note, however, that your unit may incorporate a newer, enhanced
version of the system (e.g., includes newer sounds), so what you
actually see in the display may not always match what appears in the
manual.
