IMPORTANT NOTES

291a

In addition to the items listed under “USING THE UNIT SAFELY” on page 2–3, please read and observe the following:

Power Supply: Use of Batteries

301

• Do not use this unit on the same power circuit with any

device that will generate line noise (such as an electric
motor or variable lighting system).

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 inter-
ference.

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 initi-
ating 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.

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.

Additional Precautions

551

• Please be aware that the contents of memory can be

irretrievably lost as a result of a malfunction, or the
improper operation of the unit. To protect yourself against
the risk of loosing important data, we recommend that
you periodically save a backup copy of important data
you have writed on the 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.

556

• When connecting / 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.

558a

• To avoid disturbing your neighbors, try to keep the unit’s

volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).

559a

• When you need to transport the unit, package it in the box

(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.

562

• Use a cable from Roland to make the connection. If using

some other make of connection cable, please note the
following precautions.

• Some connection cables contain resistors. Do not use

cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level
to be extremely low, or impossible to hear. For infor-
mation on cable specifications, contact the manufac-
turer of the cable.
