IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2, 
3 and 4, please read and observe the following:
Power Supply
301
• Do not use this unit on the same power circuit with any 
device that will generate line noise (such as an electric 
motor or variable lighting system).
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.
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 inter-
ference.
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.
353
• Observe the following when using the unit’s floppy disk 
drive. For further details, refer to “Before Using Floppy 
Disks” (p. 6).
• Do not place the unit near devices that produce a 
strong magnetic field (e.g., loudspeakers).
• Install the unit on a solid, level surface.
• Do not move the unit or subject it to vibration while 
the drive is operating.
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.
355
• To avoid possible breakdown, do not use the unit in a wet 
area, such as an area exposed to rain or other moisture.
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
401b
• 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.
• The pedals of this unit are made of brass.
Brass eventually darkens as the result of the natural 
oxidization process. If the brass becomes tarnished, polish 
it using commercially available metal polisher.
For KR-5-PE
• Since your piano has a polished finish that is as delicate as 
that found on finely crafted wooden furniture, it needs 
careful, periodic care. A few important suggestions 
concerning the proper care of the unit follow.
For dusting, wipe the instrument with a soft cloth 
that has been soaked with water, then squeezed dry.
Be sure to wipe gently. Even the tiniest grains of sand 
or grit can leave scratches on the surface if too much 
force is applied while wiping.
Do not use any cleaners or detergents, since they might
deteriorate the surface of the cabinet, and produce
cracks. Do not use dusting cloths that contain 
chemicals.
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 a floppy disk.
552
• Unfortunately, it may be impossible to restore the contents 
of data that was stored on a floppy disk 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.
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.
