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 connect this unit to same electrical outlet that is being 
used by an electrical appliance that is controlled by an inverter 
(such as a refrigerator, washing machine, microwave oven, or air 
conditioner), or that contains a motor. 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.
 
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 LCD and 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 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.
 
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.
 
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.
 
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.
