IMPORTANT NOTES
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.
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 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.
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 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.
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.
Repairs and Data
452
• Please be aware that all data contained in the unit’s memory
may be lost when the unit is sent for repairs. Important data
should always be written down on paper (when possible).
During repairs, due care is taken to avoid the loss of data.
However, in certain cases (such as when circuitry related to
memory itself is out of order), we regret that it may not be
possible to restore the data, and Roland assumes no liability
concerning such loss of data.
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.
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).
558c
• Since sound vibrations can be transmitted through floors and
walls to a greater degree than expected, take care not to allow
such sound to become a nuisance to neighbors, especially at
night and when using headphones. Although the drum pads
and pedals are designed so there is a minimal amount of extra-
neous sound produced when they’re struck, rubber heads tend
to produce louder sounds compared to mesh heads. You can
effectively reduce much of the unwanted sound from the pads
by switching to mesh heads.
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
• 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.
985
• The explanations in this manual include illustrations that
depict what should typically be shown by the display. Note,
however, that your unit may incorporate a newer, enhanced
version of the system (e.g., includes newer sounds), so what
you actually see in the display may not always match what
appears in the manual.
• If there is a danger that you might accidentally strike the unit
during performance, adjust the locations at which Tom 1 (T1)
and Tom 2 (T2) are attached to the stand, to reduce the gap
between the pads.
