Important Notes - Roland HP-1 Owner's Manual

1. Important notes

Power Supply
• 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).
• Before connecting the HP-1 to other devices, turn off
the power to all units. This will help prevent malfunc-
tions and/or damage to speakers or other devices.
Placement
• Using the unit near power amplifiers (or other equip-
ment containing large power transformers) may
induce hum. To alleviate the problem, change the ori-
entation of this unit; or move it farther away from the
source of interference.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicin-
ity 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.
• Do not expose the instrument to direct sunlight, place
it near devices that radiate heat, leave it inside an
enclosed vehicle, or otherwise subject it to tempera-
ture 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 spot-
lights to shine upon the same area of the unit for
extended periods of time. Excessive heat can deform
or discolor the unit.
• To avoid possible breakdown, do not use the HP-1 in a
wet area, such as an area exposed to rain or other
moisture.
• Do not allow rubber, vinyl, or similar materials to
remain on the HP-1 for long periods of time. Such
objects can discolor or otherwise harmfully affect the
finish.
• Do not put anything that contains water (e.g., flower
vases) on the piano. Also, avoid the use of insecticides,
perfumes, alcohol, nail polish, spray cans, etc., near
the unit. Swiftly wipe away any liquid that spills on the
unit using a dry, soft cloth.
• Do not allow objects to remain on the keyboard. This
can be the cause of malfunction, such as keys ceasing
to produce sound.
• Do not paste stickers, decals, or the like to this instru-
ment. 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.
• 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
HP-1's buttons, sliders, or other controls; and when
using its jacks and connectors. Rough handling can
lead to malfunctions.
• When connecting/disconnecting 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.
• A small amount of heat will radiate from the unit dur-
ing normal operation.
• To avoid disturbing your neighbors, try to keep the
unit's volume at reasonable levels. You may prefer to
use headphones.
• 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.
• 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, con-
tact the manufacturer of the cable.
