IMPORTANT NOTES
Power Supply: Use of Batteries
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.
303a
• The use of an AC adaptor is recommended as the unit’s power
consumption is relatively high. Should you prefer to use
batteries, please use the alkaline type.
304a
• When installing or replacing batteries, always turn off the
power on this unit and disconnect any other devices you may
have connected. This way, you can prevent malfunction and/
or damage to speakers or other devices.
306b
• Batteries are supplied with the unit. The life of these batteries
may be limited, however, since their primary purpose was to
enable testing.
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
temperature and/or humidity is very different, 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 portion may discolor or
mar the surface.
You can place a piece of felt or cloth under the rubber portion
to prevent this from happening. If you do so, please make sure
that the unit will not slip or move accidentally.
Add
• The snare stand is supported by means of a tripod. When
installing the drum set, make sure the legs of the tripod are
opened wide enough to keep the equipment from falling
over.
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.
Add
• The rubber portion of the striking surface is treated with a
preservative to maintain its performance. With the passage of
time, this preservative may appear on the surface as a white
stain, or reveal how the pads were struck during product
testing. This does not affect the performance or functionality
of the product, and you may continue using it with
confidence.
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. 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
551
• Stored settings can be lost due to equipment malfunction or
incorrect operation. To prevent loss of your data, please back
up important content or make a note of it on paper.
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.
554
• Never strike or apply strong pressure to the display.
555
• A small amount of noise may be heard from the display during
normal operation.
