Important Notes
 
291a
 
In addition to the items listed under “USING THE UNIT SAFELY” on page 3, please read and observe the following:
 
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.
 
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 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 paper.
 
552
 
• Unfortunately, it may be impossible to restore the contents 
of data that was stored in the unit’s 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.
 
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.
 
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).
