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.
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 unit may interfere with radio and television
reception. Do not use this unit 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.
• 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.
• 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.
Repairs and Data
• Before requesting servicing, back up the data stored
in the unit by writing down the stored information
or by using V-1SDI RCS dedicated software (p. 31).
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.
Maintenance
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
Grounding Terminal
• Depending on the circumstances of a particular setup,
you may experience a discomforting sensation, or
perceive that the surface feels gritty to the touch when
you touch this device, microphones connected to it,
or the metal portions of other objects, such as guitars.
This is due to an infinitesimal electrical charge, which
is absolutely harmless. However, if you are concerned
about this, connect the ground terminal (see figure on
page 9) with an external ground. When the unit is
grounded, a slight hum may occur, depending on the
particulars of your installation. If you are unsure of the
connection method, contact the nearest Roland Service
Center, or an authorized Roland distributor, as listed on
the “Information.”
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may be
dangerous in the event of lightning)
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
important data stored in the unit, use V-1SDI RCS
dedicated software (p. 31) to make backups.
• 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.
• 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.
• 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.
• Do not use connection cables that contain a built-in
resistor.
