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 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.
352
•This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
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.
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.

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 on a Memory card
(SmartMedia).
552
•Unfortunately, it may be impossible to restore the contents of
data that was stored in the unit’s memory, and on a Memory
card (SmartMedia) 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.
554
•Never strike or apply strong pressure to the display.
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 information on
cable specifications, contact the manufacturer of the cable.

Before Using Cards

Using Memory Cards

•Never insert or remove a memory card while the power to
the SP-303 is on.
704
•Carefully insert the Memory card all the way in—until it is
firmly in place.

•Never touch the terminals of the DATA card. Also, avoid
getting the terminals dirty.

Copyright

851

performance, or the like) whose copyright is held by a
third party is prohibited by law.

•Do not use this unit for purposes that could infringe on a
copyright held by a third party. Roland assumes no

ments of third-party copyrights arising through your use
of this unit.
