IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on p. 3 , please read and observe the following:
Power Supply
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.
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 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.
355
• To avoid possible breakdown, do not use the unit in a wet area,
such as an area exposed to rain or other moisture.
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.
Handling CD-ROMs
801
• Avoid touching or scratching the shiny underside (encoded
surface) of the disc. Damaged or dirty CD-ROM discs may not be
read properly. Keep your discs clean using a commercially
available CD cleaner.
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 stored in the unit’s memory in another
MIDI device (e.g., a sequencer).
552
• Unfortunately, it may be impossible to restore the contents of
data that was stored in another MIDI device (e.g., a sequencer)
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.
924
• To prevent the inadvertent disruption of power to your unit
(should the plug be pulled out accidentally), and to avoid
applying undue stress to the AC adaptor jack, anchor the power
cord using the cord hook, as shown in the illustration.
927
• In some cases, depending on the environment in which the unit is
installed, the surface of the panel may sometimes feel rough and
grainy. This is due to an infinitesimal electrical charge, which is
absolutely harmless. However, if you are concerned about this,
connect the ground terminal (see figure) with an external ground.
When the unit is grounded, a slight hum may occur, depending
on the particulars of your installation. If you are unsure of the
connection method, contact the nearest Roland Service Center, or
an authorized Roland distributor, as listed on the “Information”
page.
Unsuitable places for connection
- Water pipes (may result in shock or electrocution)
- Gas pipes (may result in fire or explosion)
- Telephone-line ground or lightning rod (may be dangerous in
the event of lightning)
