IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT 
SAFETY INSTRUCTIONS” and “USING THE UNIT 
SAFELY” on pages 2 and 3, please read and observe the 
following:
Power Supply
Power Supply: Use of 
Batteries
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 inter-
ference.
352
• This device may interfere with radio and television 
reception. Do not use this device in the vicinity of such 
receivers.
354a
• 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. 
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.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth 
or one that has been slightly dampened with water. To 
remove stubborn dirt, use a cloth impregnated with a 
mild, non-abrasive detergent. Afterwards, be sure to wipe 
the unit thoroughly with a soft, dry cloth.
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.
554
• Never strike or apply strong pressure to the display.
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 infor-
mation on cable specifications, contact the manufac-
turer of the cable.
Handling CD-ROMs
801
• Avoid touching or scratching the shiny underside 
(encoded surface) of the disc. Damaged or dirty CD-ROM 
discs may not be read properly. Keep your discs clean 
using a commercially available CD cleaner.
