Important Notes - Roland VR-50HD 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.
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.
• 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 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
• 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
• Before sending the unit away for repairs, be
sure to make a backup of the data stored
within it; or you may prefer to write down
the needed information. Although we will
do our utmost to preserve the data stored in
your unit when we carry out repairs, in some
cases, such as when the memory section is
physically damaged, restoration of the stored
content may be impossible. Roland assumes
no liability concerning the restoration of any
stored content that has been lost.
Additional Precautions
• Any data stored within the unit can be lost
as the result of equipment failure, incorrect
operation, etc. To protect yourself against the
irretrievable loss of data, try to make a habit
of creating regular backups of the data you've
stored in the unit.
• Roland assumes no liability concerning the
restoration of any stored content that has
been lost.
• 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.
• 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.
• 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.
• This unit allows you to switch images at
high speed. For some people, viewing such
images can cause headache, nausea, or other
discomfort. Do not use this unit to create
video that might cause these types of health
problems. Roland Corporation will accept no
responsibility for any such health problems
that may occur in yourself or in viewers.

• Please observe the following precautions
when handling USB flash drive.
Also, make sure to carefully observe all the
precautions that were supplied with the
external memory device.
