IMPORTANT NOTES
301
●
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.
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-edit
●
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.
307
●
To prevent malfunction and equipment failure, always
make sure to turn off the power on all your equipment
before you make any connections.
322
●
When installing or replacing batteries, always turn this
unit off and disconnect any other devices you may have
connected. This way, you can prevent malfunction and
damage.
325
●
A battery was installed in the remote controller before it
left the factory. The life of this battery may be limited,
however, since its primary purpose was to enable testing.
327-edit
●
If the batteries run extremely low, the sound may distort /
interruptions in the sound may occur at high volume
levels, but this does not indicate a malfunction. If this
occurs, please replace the batteries / use the included AC
adaptor.
328-edit
●
If operating this unit on batteries, please use alkaline
batteries or rechargeable Ni-MH batteries.
329
●
If operating this unit on batteries, please disconnect the
AC adaptor from this unit.
330-edit
●
Even if batteries are installed, the unit will turn off if you
connect or disconnect the power cord from the AC outlet
while the unit is turned on, or if you connect or
disconnect the AC adaptor from the unit. When this
occurs, unsaved data may be lost. You must turn off the
power before you connect or disconnect the power cord
or AC adaptor.
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 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.
361
●
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.
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.
452-edit
●
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 backed up SD cards,
SDHC cards, or 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.

●
Avoid touching or scratching the shiny underside
(encoded surface) of the disc. Damaged or dirty discs may
not be read properly. Keep your discs clean using a
commercially available disc cleaner.
