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 lter 
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.
Placement
•  Using the unit near power ampliers (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 unit may interfere with radio and television 
reception. Do not use this unit 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 o.
•  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 dierent, 
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 place containers or anything else containing 
liquid on top of this unit. Also, whenever any liquid 
has been spilled on the surface of this unit, be sure 
to promptly wipe it away using a soft, dry 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
•  Before sending the unit away for repairs, be sure to 
make a backup of the data stored within it; or you 
may prefer to write down the needed information. 
Although we will do our utmost to preserve the 
data stored in your unit when we carry out repairs, 
in some cases, such as when the memory section is 
physically damaged, restoration of the stored 
content may be impossible. Roland assumes no 
liability concerning the restoration of any stored 
content that has been lost.
Additional Precautions
•  Any data stored within the unit can be lost as the 
result of equipment failure, incorrect operation, etc. 
To protect yourself against the irretrievable loss of 
data, try to make a habit of creating regular 
backups of the data you’ve stored in the unit.
•  Roland assumes no liability concerning the 
restoration of any stored content that has been lost.
•  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.
•  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. Please take care not to cause 
annoyance to others nearby.
•  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.
•  Use only the specied expression pedal (EV-5; sold 
separately). By connecting any other expression 
pedals, you risk causing malfunction and/or 
damage to the unit.
Using External Memories
•  Please observe the following precautions when 
handling external memory devices. Also, make sure 
to carefully observe all the precautions that were 
supplied with the external memory device.
•  Do not remove the device while reading/writing 
is in progress.
•  To prevent damage from static electricity, 
discharge all static electricity from your person 
before handling the device.
