IMPORTANT NOTES

291b
In addition to the items listed under "IMPORTANT SAFETY INSTRUCTIONS" and "USING THE UNIT SAFELY" on pages
2–4, 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
• When it is necessary to switch off the power completely, first
switch off the unit's power switch, then unplug its power cord
from the outlet. To facilitate doing this, you should plug the
power cord into an outlet that is as close to the unit as possible,
and can be easily reached when necessary.
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.
355b
• When moved from one location to another where the temper-
ature and/or humidity is very different, water droplets (conden-
sation) 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.
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.
Add
• Do not allow objects to remain on top of the unit while it is in
operation. Placing heavy objects on this unit may result in injury
if it overturns or falls.

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.
Add
• Be sure to avoid inserting your fingers in the bass reflex ports
when transporting or moving the speakers, as your fingers may
become wedged and stuck in the ports.
562
• Use a cable from Roland to make the connection. If using some
other make of connection cable, please note the following precau-
tions.
• 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.
