IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT
SAFELY” on pages 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.
■
Placement
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
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 Corporation 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.
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).
