IMPORTANT NOTES

291b
In addition to the items listed under "IMPORTANT SAFETY INSTRUCTIONS" and "USING THE UNIT SAFELY" on pages 2
and 3–4, please read and observe the following:

Power Supply

301
• Do not use this unit on the same power circuit with any device
that will generate line noise (such as an electric motor or variable
lighting system).
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.
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.
354b
• 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.
355
• To avoid possible breakdown, do not use the unit in a wet area,
such as an area exposed to rain or other moisture.
356
• Do not allow rubber, vinyl, or similar materials to remain on the
unit for long periods of time. Such objects can discolor or
otherwise harmfully affect the finish.
357
• Do not put anything that contains water (e.g., flower vases) on
the 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.
359
• Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the exterior
finish.
4
107a
• Never handle the power cord or its plug with wet
hands when plugging into, or unplugging from,
an outlet.
..........................................................................................................
108a
• Before moving the unit, disconnect the power
plug from the outlet, and pull out all cords from
external devices.
..........................................................................................................
109a
• Before cleaning the unit, turn off the power and
unplug the power cord from the outlet.
..........................................................................................................
110a
• Whenever you suspect the possibility of lightning
in your area, pull the plug on the power cord out
of the outlet.
..........................................................................................................

Maintenance

401b
• 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.
402
• Never use benzine, thinners, alcohol or solvents of any kind, to
avoid the possibility of discoloration and/or deformation.

Additional Precautions

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.
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.
557
• A small amount of heat will radiate from the unit during normal
operation.
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.
562
• Use a cable from Roland to make the connection. If using some other
make of connection cable, please note the following precautions.
• 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.
921
• To prevent malfunction and/or damage to speakers or other
devices, always turn down the volume, and turn off the power on
all devices before making any connections.
941
• Once the connections have been completed, turn on power to
your various devices in the order specified. By turning on devices
in the wrong order, you risk causing malfunction and/or damage
to speakers and other devices.
When powering up: Turn on the power to the CUBE-30 last .
When powering down: Turn off the power to the CUBE-30 first .
• Wrap the AC cord around the cord hook when trans-porting or
storing the unit.
