IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on pages 2 – 3, 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).
302
The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
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.
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 initi-
ating 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.
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
551
Please be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself
against the risk of loosing important data, we
recommend that you periodically save a backup copy of
important data you have stored in the unit’s memory in
another MIDI device (e.g., a sequencer).
552
Unfortunately, it may be impossible to restore the
contents of data that was stored in another MIDI device
(e.g., a sequencer) once it has been lost. Roland Corpo-
ration assumes no liability concerning such loss of data.
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.
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.
Before Using Memory Cards
704
Carefully insert the memory card all the way in—until it is
firmly in place.
705
Never touch the terminals of the memory card. Also,
avoid getting the terminals dirty.

performance, broadcasting, or the like, in whole or in part,
