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 filter between 
this unit and the electrical outlet.
 
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.
 
308
 
Although the LCD and LEDs are switched off when the 
POWER switch is switched off, this does not mean that the 
unit has been completely disconnected from the source of 
power. If you need to turn off the power completely, first turn 
off 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
 
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 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.
 
354b
 
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.
 
355b
 
When moved from one location to another where the temper-
ature 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.
 
356
 
Do not allow rubber, vinyl, or similar materials to remain on 
the unit for long periods of time. Such objects can discolor or 
otherwise harmfully affect the finish.
 
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.
 
359
 
Do not paste stickers, decals, or the like to this instrument. 
Peeling such matter off the instrument may damage the 
exterior finish.
 
Maintenance
 
To clean the unit, use a dry, soft cloth; or one that is slightly 
dampened. Try to wipe the entire surface using an equal 
amount of strength, moving the cloth along with the grain of 
the wood. Rubbing too hard in the same area can damage the 
finish.
 
402
 
Never use benzine, thinners, alcohol or solvents of any kind, 
to avoid the possibility of discoloration and/or deformation.
 
Additional Precautions
 
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.
 
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 (especially when it is late at night).
 
559b
 
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.
 
560
 
Do not apply undue force to the music stand while it is in use.
 
562
 
Use a cable from Roland to make the connection. If using 
some other make of connection cable, please note the 
following precautions.
• 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.
