Power Supply
• Do not connect this unit to same electrical outlet
that is being used by an electrical appliance that
is controlled by an inverter or a motor (such as a
refrigerator, washing machine, microwave oven, or
air conditioner). 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.
• The AC adaptor will begin to generate heat after
long hours of consecutive use. This is normal, and is
not a cause for concern.
Power Supply: Use of Batteries
• Before installing/removing batteries, make sure to
turn off the power to this unit and disconnect all
connections to other devices.
• If operating this unit on batteries, please use
rechargeable Ni-MH batteries or Alkaline batteries.
Placement
• 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.
• This unit may interfere with radio and television
reception. Do not use this unit in the vicinity of such
receivers.
• 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.
• 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.
• 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.
• 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.
• Do not place containers or anything else containing
liquid on top of this unit. Also, whenever any liquid
has been spilled on the surface of this unit, be sure
to promptly wipe it away using a soft, dry cloth.
Maintenance
• 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.
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
Additional Precautions
• 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.
• When 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.
• To avoid disturbing others nearby, try to keep the
unit’s volume at reasonable levels.
• When you need to transport the unit, pack it in
shock-absorbent material. Transporting the unit
without doing so can cause it to become scratched
or damaged, and could lead to malfunction.
CAUTION
Place in a well ventilated location
The unit and the AC adaptor should be
located so their location or position does
not interfere with their proper ventilation.
Use only the specified stand(s)
This unit is designed to be used in
combination with specific stands (ST-
A95) manufactured by Roland. If used
in combination with other stands, you
risk sustaining injuries as the result of this product
dropping down or toppling over due to a lack of
stability.
Evaluate safety issues before using stands
Even if you observe the cautions given
in the owner’s manual, certain types of
handling may allow this product to fall
from the stand, or cause the stand to
overturn. Please be mindful of any safety issues before
using this product.
When disconnecting the power cord, grasp it by
the plug
To prevent conductor damage, always
grasp the power cord by its plug when
disconnecting it from this unit or from a
power outlet.
Periodically clean the power plug
An accumulation of dust or foreign objects
between the power plug and the power
outlet can lead to fire or electric shock.
At regular intervals, be sure to pull out the
power plug, and using a dry cloth, wipe away any dust
or foreign objects that may have accumulated.
CAUTION
Disconnect the power plug whenever the unit will
not be used for an extended period of time
Fire may result in the unlikely event that a
breakdown occurs.
Route all power cords and cables in such a way as
to prevent them from getting entangled
Injury could result if someone were to trip
on a cable and cause the unit to fall or
topple.
Avoid climbing on top of the unit, or placing heavy
objects on it
Otherwise, you risk injury as the result of
the unit toppling over or dropping down.
Never connect/disconnect a power plug if your
hands are wet
Otherwise, you could receive an electric
shock.
Disconnect all cords/cables before moving the unit
Before moving the unit, disconnect the
power plug from the outlet, and pull out all
cords from external devices.
Before cleaning the unit, disconnect the power
plug from the outlet
If the power plug is not removed from the
outlet, you risk receiving an electric shock.
Whenever there is a threat of lightning, disconnect
the power plug from the outlet
If the power plug is not removed from the
outlet, you risk receiving an electric shock.
CAUTION
Handle batteries carefully
If used improperly, batteries may explode
or leak and cause damage or injury. In the
interest of safety, please read and observe
the following precautions.
• Carefully follow the installation
instructions for batteries, and make sure
you observe the correct polarity.
• Avoid using new batteries together with
used ones. In addition, avoid mixing
different types of batteries.
• Remove the batteries whenever the unit is to
remain unused for an extended period of time.
• Never keep batteries together with metallic objects
such as ballpoint pens, necklaces, hairpins, etc.
• Used batteries must be disposed of in compliance
with whatever regulations for their safe disposal
that may be observed in the region in which you
live.
Take care not to get burned
Batteries may reach a high temperature;
please be careful to avoid burning yourself.
Handle leaking batteries carefully
• Do not touch the liquid with your bare
hands.
• If any of the leaking fluid gets into your
eyes, the loss of vision may result. Do
not rub your eyes; use clean water to
flush them thoroughly. Then, promptly
see a doctor.
• Burning of the skin or dermatitis may result if fluid
has gotten onto your skin or clothing. Use clean
water to flush affected areas thoroughly; then,
promptly see a doctor.
• Using a soft cloth, carefully wipe any remaining
fluid from the inside of the battery compartment.
Then, install new batteries.
