Important Notes - Roland JUNO-Di Owner's Manual

IMPORTANT NOTES

Power Supply: Use of Batteries
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.
302
• The AC adaptor will begin to generate heat after long hours of
consecutive use. This is normal, and is not a cause for concern.
303a
• The use of an AC adaptor is recommended as the unit's power
consumption is relatively high. Should you prefer to use batteries,
please use the nickel-metal hydride type.
304a
• When installing or replacing batteries, always turn off the power on
this unit and disconnect any other devices you may have connected.
This way, you can prevent malfunction and/or damage to speakers or
other devices.
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.
Add
• If you're using batteries, disconnect the AC adaptor from this unit.
Add
• If batteries are installed, disconnecting or reconnecting the power
cord at the AC outlet or disconnecting the DC plug from the unit's
rear panel while the power is on will cause the power to turn off. You
must turn off the power before you connect or disconnect the power
cord or AC adaptor.
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.
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 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.
354a
• 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.
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.
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.
360
• 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.

Maintenance
401a
• 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.
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 USB memory, 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
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 USB memory.
552
• Unfortunately, it may be impossible to restore the contents of data
that was stored in the unit's memory or on a USB memory 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.
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.
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).
559a
• 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.
561
• 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.
562
• 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.
566a
• 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.
566b
• 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.
