USING THE UNIT SAFELY

002b

• Do not open or perform any internal
modifications on the unit. (The only
exception would be where this manual
provides specific instructions which
should be followed in order to put in
place user-installable options.)

.......................................................................................................................

003

• Do not attempt to repair the unit, or
replace parts within it (except when this
manual provides specific instructions
directing you to do so). Refer all servicing
to your retailer, the nearest Roland
Service Center, or an authorized Roland
distributor, as listed on the “Information.”

.......................................................................................................................

004

• Never install the unit in any of the
following locations.

• Subject to temperature extremes (e.g.,

direct sunlight in an enclosed vehicle,
near a heating duct, on top of heat­generating equipment); or are

• Damp (e.g., baths, washrooms, on wet

floors); or are

• Exposed to steam or smoke; or are

• Subject to salt exposure; or are

• Humid; or are

• Exposed to rain; or are

• Dusty or sandy; or are

• Subject to high levels of vibration and

shakiness.

.......................................................................................................................

005

• This unit should be used only with a
stand (MDS series) that is recommended
by Roland.

.......................................................................................................................

006

• When using the unit with a stand (MDS
series) recommended by Roland, the
stand (MDS series) must be carefully
placed so it is level and sure to remain
stable. If not using a stand (MDS series),
you still need to make sure that any
location you choose for placing the unit
provides a level surface that will properly
support the unit, and keep it from
wobbling.

.......................................................................................................................

011

• Do not allow any objects (e.g., flammable
material, coins, pins); or liquids of any
kind (water, soft drinks, etc.) to penetrate
the unit.

.......................................................................................................................

013

• In households with small children, an
adult should provide supervision until
the child is capable of following all the
rules essential for the safe operation of
the unit.

.......................................................................................................................

014

• Do not drop the unit.

.......................................................................................................................

104

• Try to prevent cords and cables from
becoming entangled. Also, all cords and
cables should be placed so they are out
of the reach of children.

.......................................................................................................................

106

• Never climb on top of, nor place heavy
objects on the unit.

.......................................................................................................................

118c

• Should you remove remove nuts,
washers, screws, anchor bolts, etc., keep
them in a safe place out of children’s
reach, so there is no chance of them
being swallowed accidentally.

.......................................................................................................................

Used for instructions intended to alert the
user to the risk of injury or material
damage should the unit be used
improperly.

* Material damage refers to damage or

other adverse effects caused with
respect to the home and all its
furnishings, as well to domestic animals
or pets.

Used for instructions intended to alert the
user to the risk of death or severe injury
should the unit be used improperly.

The

● symbol alerts the user to things that must be

carried out. The specific thing that must be done is
indicated by the design contained within the circle. In the
case of the symbol at left, it means that the power-cord
plug must be unplugged from the outlet.

The symbol alerts the user to important instructions or
warnings.The specific meaning of the symbol is
determined by the design contained within the triangle. In
the case of the symbol at left, it is used for general
cautions, warnings, or alerts to danger.

The symbol alerts the user to items that must never be
carried out (are forbidden). The specific thing that must
not be done is indicated by the design contained within
the circle. In the case of the symbol at left, it means that
the unit must never be disassembled.

Placement

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.

356

• Do not allow rubber, vinyl, or similar materials to remain on the unit for long periods of
time. Such objects can discolor or otherwise harmfully affect the finish.

• When setting up or storing this unit, be careful so the fingers used to grasp the stand
don’t get pinched. Also, take care that the stand does not become unbalanced and fall
over or fall against you.

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

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).

558d

• This instrument is designed to minimize the extraneous sounds produced when it’s
played. However, since sound vibrations can be transmitted through floors and walls to a
greater degree than expected, take care not to allow these sounds to become a nuisance
to neighbors, especially when performing at night and when using headphones.

562

• 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.

• The rubber portion of the striking surface is treated with a preservative to maintain its
performance. With the passage of time, this preservative may appear on the surface as a
white stain, or reveal how the pads were struck during product testing. This does not
affect the performance or functionality of the product, and you may continue using it with
confidence.

• Continuous playing may cause dis-coloration of the pad, but this will not affect the Pad’s
function.

962a

• In the interest of product improvement, the specifications and/or appearance of this unit
are subject to change without prior notice.
