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 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
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.
352
• This device may interfere with radio and television reception.
Do not use this device in the vicinity of such receivers.
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 piano 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 the HPi-5 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.
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.
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.
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.
