IMPORTANT NOTES
291a
In addition to the items listed under USING THE UNIT SAFELY on page 23, 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 units memory on a Memory card
(SmartMedia).
552
Unfortunately, it may be impossible to restore the contents of
data that was stored in the units 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 units
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 itselfnever pull on the cable. This way you
will avoid causing shorts, or damage to the cables
internal elements.
558a
To avoid disturbing your neighbors, try to keep the units
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 inuntil it is
firmly in place.
