IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2,
3, 4 and 5, 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).
306b
• A batteries are supplied with the unit. The life of this
battery may be limited, however, since its primary
purpose was to enable testing.
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 acces-
sible.
.
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. 7).
• 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.
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.
• 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
• 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, using a soft, clean cloth and/or piano-use
feather duster. 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.
• If the cabinet’s surface loses its luster, wipe it
thoroughly with a soft cloth dampened with a little of
the polishing liquid.
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.
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
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 on a floppy
disk, 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.
