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 lter
between this unit and the electrical outlet.
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 o 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 ampliers (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 o.
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.
355b
• When moved from one location to another where the temperature
and/or humidity is very dierent, water droplets (condensation)
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.
360
• Depending on the material and temperature of the surface on which
you place the unit, its rubber feet may discolor or mar the surface.
You can place a piece of felt or cloth under the rubber feet to
prevent this from happening. If you do so, please make sure that the
unit will not slip or move accidentally.
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
552
• Unfortunately, it may be impossible to restore the contents of data
that was stored in the unit’s memory 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.
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 (includ-
ing padding) that it came in, if possible. Otherwise, you will need to
use equivalent packaging materials.
562
• 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 specications, contact the
manufacturer of the cable.
