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 (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.
•  The AC adaptor will begin to generate heat after long hours of consecutive 
use. This is normal, and is not a cause for concern.
•  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.
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 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 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. 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 powerful spotlights to shine upon the same area of the unit for 
extended periods of time. 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 rubber, vinyl, or similar materials to remain on this unit for 
long periods of time. Such objects can discolor or otherwise harmfully 
aect the nish.
•  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.
•  Do not paste stickers, decals, or the like to this instrument. Peeling such 
matter o the instrument may damage the exterior nish.
•  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 (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
•  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 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
•  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.
•  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.
•  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 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.
•  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.
•  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.
•  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 specied expression pedal (EV-5; 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 specications, contact the manufacturer of the cable.
