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

301

• Do not connect this unit to same electrical

outlet that is being used by an electrical
appliance that is controlled by an inverter
(such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that
contains a motor. 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.

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 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 communi-

cations 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.

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.

Repairs and Data

452

• 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 in another MIDI device
(e.g., a sequencer), computer, 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.
