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.

801

●

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.
