IMPORTANT NOTES
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  lter 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.
• 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 batteries or
rechargeable Ni-MH batteries.
• If the unit has been used with a
power supply that has not been
speci ed as suitable for the unit,
the subsequent performance and
operation of the unit can no longer
be guaranteed. Also note that we
may not be able to accept the unit
for servicing and repairs.
Power Supply: Use of Batteries
• Before installing/removing batteries,
make sure to turn o the power
to this unit and disconnect all
connections to other devices.
• If operating this unit on batteries,
please use the alkaline batteries or
rechargeable Ni-MH batteries.
Placement
• Using the unit near power ampli ers
(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 o .
• 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 di erent,
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.
Repairs and Data
• Before sending the unit away for
repairs, be sure to make a backup
of the data stored within it; or
you may prefer to write down the
needed information. Although we
will do our utmost to preserve the
data stored in your unit when we
carry out repairs, in some cases,
such as when the memory section
is physically damaged, restoration
of the stored content may be
impossible. Roland assumes no
liability concerning the restoration
of any stored content that has been
lost.
Additional Precautions
• Any data stored within the unit can
be lost as the result of equipment
failure, incorrect operation, etc.
To protect yourself against the
irretrievable loss of data, try to make
a habit of creating regular backups
of the data you’ve stored in the unit.
• Roland assumes no liability
concerning the restoration of any
stored content that has been lost.
• 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.
• Never strike or apply strong
pressure to the display.
• 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.
Using External Memories
• Please observe the following
precautions when handling external
memory devices.
Also, make sure to carefully observe
all the precautions that were
supplied with the external memory
device.
• Do not remove the device while
reading/writing is in progress.
• To prevent damage from static
electricity, discharge all static
electricity from your person
before handling the device.
