IMPORTANT NOTES
In addition to the items listed under “USING THE UNIT SAFELY” on page 2 -3, please read and observe the
following:
following:
Power Supply
•
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).

motor or variable lighting system).
•
The AC adaptor will begin to generate heat after long hours
of consecutive use. This is normal, and is not a cause for
concern.

concern.
•
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.

and/or damage to speakers or other devices.
Placement
•
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.

This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.

receivers.
•
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.

•
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.

•
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.

Do not allow objects to remain on top of the keyboard. This
can be the cause of malfunction, such as keys ceasing to
produce sound.

Maintenance
•
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.

Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.

Repairs and Data
•
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), 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
memory may be lost when the unit is sent for repairs.

Additional Precautions
•
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).

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.

•
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.

•
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).

•
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.

Use only the specified expression pedal (EV-**; sold
separately). By connecting any other expression pedals, you
risk causing malfunction and/or damage to the unit.

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 information on cable
specifications, contact the manufacturer of the cable.

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.
