Important Notes
 
291b
 
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 3 and 4–6, 
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.
 
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 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
 
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 
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 
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.
 
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.
 
Addition
 
• If water droplets should adhere to this device, immediately 
wipe them off using a soft dry cloth.
 
402
 
• Never use benzine, thinners, alcohol or solvents of any 
kind, to avoid the possibility of discoloration and/or 
deformation.
 
403
 
• 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.
 
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 backed up in another 
MIDI device (e.g., a sequencer), 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.
