Power Supply
• Do not connect this unit to same electrical outlet
that is being used by an electrical appliance that
is controlled by an inverter or a motor (such as a
refrigerator, washing machine, microwave oven, or
air conditioner). 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.
• The AC adaptor will begin to generate heat after
long hours of consecutive use. This is normal, and is
not a cause for concern.
• To prevent malfunction and equipment failure,
always make sure to turn off the power on all your
equipment before you make any connections.
• With the factory settings, the HPi-50e will
automatically be switched off 30 minutes after you
stop playing or operating the unit. If you don’t want
the unit to turn off automatically, change the “AUTO
OFF” setting to “OFF” as described on p. 52.
NOTE
The settings you were editing will be lost when the
unit is turned off. If you want to keep your settings,
you must save your settings before turning the unit
off.
Placement
• 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.
• 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
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.
• 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.
• 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.
• Do not allow rubber, vinyl, or similar materials to
remain on this 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.
• Do not paste stickers, decals, or the like to this
instrument. Peeling such matter off the instrument
may damage the exterior finish.
• Do not place containers or anything else containing
liquid on top of this unit. Also, whenever any liquid
has been spilled on the surface of this unit, be sure
to promptly wipe it away using a soft, dry cloth.
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.
• 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.
• Since wood will expand and contract depending
on how it is used and the environment in which it is
located, products made of wood may experience a
gradual loosening of the screws over time. To ensure
that your piano remains in safe, optimal condition,
you should regularly check the tightness of the
screws in the locations shown in the illustration. If
you find that any screws are Loose, use a screwdriver
to tighten them.
Repairs and Data
• 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
USB flash drives, 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.
Additional Precautions
• 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 USB flash drives.
• Unfortunately, it may be impossible to restore
the contents of data that was stored in the unit’s
memory, USB flash drives once it has been lost.
Roland Corporation assumes no liability concerning
such loss of data.
• 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.
• Never strike or apply strong pressure to the display.
• When 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.
• To avoid disturbing others nearby, 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.
• The sound of keys being struck and vibrations
produced by playing an instrument can be
transmitted through a floor or wall to an unexpected
extent. Please take care not to cause annoyance to
others nearby.
• When you need to transport the unit, package it
in the box (including padding) that it came in, if
possible. Otherwise, you will need to use equivalent
packaging materials.
• Do not apply undue force to the music stand while
it is in use.
• 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, contact
the manufacturer of the cable.
• Before opening or closing the keyboard lid, always
make sure that no pets or other small animals are
located on top of the instrument (in particular, they
should be kept away from the keyboard and its
lid). Otherwise, due to the structural design of this
instrument, small pets or other animals could end
up getting trapped inside it. If such a situation is
encountered, you must immediately turn off the unit
and disconnect the power cord from the outlet. You
should then consult with the retailer from whom the
instrument was purchased, or contact the nearest
Roland Service Center.
• When opening or closing the lid or operating the
pedals, please be careful not to get your fingers
pinched between the movable part and the panel. In
places where small children are present, make sure
that an adult provides supervision and guidance.
Before Using External Memories
Using External Memories
• Carefully insert the USB flash drives all the way in—
until it is firmly in place.
• Never touch the terminals of the USB flash drives.
Also, avoid getting the terminals dirty.
