Important Notes - Roland Jupiter-50 Owner's Manual

IMPORTANT NOTES

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 JUPITER-50 will
automatically be switched off four hours 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. 79.
* 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. 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 objects to remain on top of
the keyboard. This can be the cause of
malfunction, such as keys ceasing to produce
sound.
4
• Depending on the material and temperature
of the surface on which you place the unit, its
rubber feet may discolor or mar the surface.
You can place a piece of felt or cloth
under the rubber feet to prevent this from
happening. If you do so, please make
sure that the unit will not slip or move
accidentally.
• Do not put anything that contains water on
this unit. 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.
Maintenance
• For everyday cleaning wipe the unit with a
soft, dry cloth or one that has been slightly
dampened with water. To remove stubborn
dirt, use a cloth impregnated with a mild,
non-abrasive detergent. Afterwards, be sure
to wipe the unit thoroughly with a soft, dry
cloth.
• Never use benzine, thinners, alcohol or
solvents of any kind, to avoid the possibility
of discoloration and/or deformation.
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 on USB flash drives.
• Unfortunately, it may be impossible to
restore the contents of data that was stored
in the unit's memory or 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.
• Use only the specified expression pedal
(EV-5; sold separately). By connecting any
other expression pedals, you risk causing
malfunction and/or damage to the unit.
• 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.
• The usable range of D-BEAM controller will
become extremely small when used under
strong direct sunlight. Please be aware of this
when using the D-BEAM controller outside.
• The sensitivity of the D-BEAM controller
will change depending on the amount of
light in the vicinity of the unit. If it does not
function as you expect, adjust the sensitivity
as appropriate for the brightness of your
location.
• When operating an expression pedal, or
opening and closing the USB memory cover,
please take care not to pinch your fingers or
toes between a moving part and the main
unit. In places where small children are
present, make sure that an adult provides
supervision and guidance.
