• The unit should be located so that its location or position
does not interfere with its proper ventilation.
.........................................................................................................................................
102a
• Always grasp only the plug on the power-supply cord
when plugging into, or unplugging from an outlet.
.........................................................................................................................................
103a:
• Any accumulation of dust between the power plug and
the power outlet can result in poor insulation and lead to
fire. Periodically wipe away such dust with a dry cloth.
Also, disconnect the power plug from the power outlet
whenever the unit is to remain unused for an extended
period of time.
.........................................................................................................................................
104
• Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be placed so
they are out of the reach of children.
.........................................................................................................................................
106
• Never climb on top of, nor place heavy objects on the
unit.
.........................................................................................................................................

IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2, 3 and 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.
308
• Although the LEDs are switched off when the POWER switch is switched
off, this does not mean that the unit has been completely disconnected from
the source of power. If you need to turn off the power completely, first turn
off the POWER switch, then unplug the power cord from the power outlet.
For this reason, the outlet into which you choose to connect the power
cord’s plug should be one that is within easy reach.
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 inter-
ference.
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 temper-
ature 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.
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.
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.
359
• Do not paste stickers, decals, or the like to this instrument. Peeling such
matter off the instrument may damage the exterior finish.
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 equiv-
alent 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 incor-
porate 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.
926
• When connection cables with resistors are used, the volume level of
equipment connected to the inputs (INPUT and AUX IN jacks) may be low.
If this happens, use connection cables that do not contain resistors, such as
those from the Roland PCS series.
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 BASS
last
.
When powering down:
Turn off the power to the CUBE-30 BASS
first
.
943
• Always make sure to have the volume level turned down before switching
on power. Even with the volume all the way down, you may still hear some
sound when the power is switched on, but this is normal, and does not
indicate a malfunction.
• Wrap the AC cord around the cord hook when trans-porting or storing the
unit.
