■ Snare Pad Handling
WARNING
Do not open (or modify in any way) the
unit or its AC adaptor.
Do not attempt to repair the unit, or
replace parts within it (except when this
manual provides specic 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” page.
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 heat-generating
equipment); or are
• Damp (e.g., baths, washrooms, on
wet oors); 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.
Make sure you always have the unit
placed so it is level and sure to remain
stable. Never place it on stands that
could wobble, or on inclined surfaces.
Be sure to use only the AC adaptor
supplied with the unit. Also, make
sure the line voltage at the installation
matches the input voltage specied
on the AC adaptor’s body. Other AC
adaptors may use a dierent polarity,
or be designed for a dierent voltage,
so their use could result in damage,
malfunction, or electric shock.
Use only the attached power-supply
cord. Also, the supplied power cord
must not be used with any other
device.
Do not excessively twist or bend the
power cord, nor place heavy objects
on it. Doing so can damage the cord,
producing severed elements and short
circuits. Damaged cords are re and
shock hazards!
This unit, in combination with an ampli-
er and headphones or speakers, may
be capable of producing sound levels
that could cause permanent hearing
loss. Do not operate for a long period of
time at a high volume level, or at a level
that is uncomfortable. If you experience
any hearing loss or ringing in the ears,
you should immediately stop using the
unit, and consult an audiologist.
WARNING
Do not place containers containing
liquid on this product. Never allow
foreign objects (e.g., ammable objects,
coins, wires) or liquids (e.g., water or
juice) to enter this product. Doing
so may cause short circuits, faulty
operation, or other malfunctions.
Immediately turn the power o, remove
the AC adaptor from the outlet, and
request servicing by your retailer, the
nearest Roland Service Center, or an
authorized Roland distributor, as listed
on the “Information” page when:
• The AC adaptor, the power-
supply cord, or the plug has been
damaged; or
• If smoke or unusual odor occurs
• Objects have fallen into, or liquid
has been spilled onto the unit; or
• The unit has been exposed to rain
(or otherwise has become wet); or
• The unit does not appear to
operate normally or exhibits a
marked change in performance.
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.
Protect the unit from strong impact.
(Do not drop it!)
Do not force the unit’s power-
supply cord to share an outlet with
an unreasonable number of other
devices. Be especially careful when
using extension cords—the total power
used by all devices you have connected
to the extension cord’s outlet must
never exceed the power rating (watts/
amperes) for the extension cord.
Excessive loads can cause the insulation
on the cord to heat up and eventually
melt through.
Before using the unit in a foreign
country, consult with your retailer, the
nearest Roland Service Center, or an
authorized Roland distributor, as listed
on the “Information” page.
CAUTION
The unit and the AC adaptor should
be located so their location or position
does not interfere with their proper
ventilation.
Always grasp only the plug on the AC
adaptor cord when plugging into, or
unplugging from, an outlet or this unit.
At regular intervals, you should unplug
the AC adaptor and clean it by using
a dry cloth to wipe all dust and other
accumulations away from its prongs.
Also, disconnect the power plug from
the power outlet whenever the unit
is to remain unused for an extended
period of time. Any accumulation of
dust between the power plug and
the power outlet can result in poor
insulation and lead to re.
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.
Never climb on top of, nor place heavy
objects on the unit.
Never handle the AC adaptor or its
plugs with wet hands when plugging
into, or unplugging from, an outlet or
this unit.
Before moving the unit, disconnect the
AC adaptor and all cords coming from
external devices.
Before cleaning the unit, turn o the
power and unplug the AC adaptor from
the outlet.
Whenever you suspect the possibility of
lightning in your area, disconnect the
AC adaptor from the outlet.

Detaching the Pedal Unit
To detach the pedal unit, reverse the procedure described in "02 Attach
the Foot Pipes" (other side).
Power Supply
• Do not connect this unit to same electrical
outlet that is being used by an electrical
appliance that is controlled by an inverter
(such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that
contains a motor. Depending on the way
in which the electrical appliance is used,
power supply noise may cause this unit to
malfunction or may produce audible noise. If
it is not practical to use a separate electrical
outlet, connect a power supply noise lter
between this unit and the electrical outlet.
• The AC adaptor will begin to generate heat
after long hours of consecutive use. This is
normal, and is not a cause for concern.
• Before connecting this unit to other devices,
turn o the power to all units. This will help
prevent malfunctions and/or damage to
speakers or other devices.
• With the factory settings, the HD-3’s power
will automatically be switched o 30 minutes
after you stop playing or operating the
unit. If you don’t want the power to turn o
automatically, change the “AUTO OFF” setting
to “OFF” as described on p. 15 of the Owner’s
Manual.
(Note)
The settings you were editing will be lost
when the power is turned o. If you want
to keep your settings, you must save your
settings before turning the power o.
Placement
• Using the unit near power ampliers (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.
• 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 o.
• 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 dierent, 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.
• Depending on the material and temperature
of the surface on which you place the unit, its
rubber feet may discolor or mar the surface.
You can place a piece of felt or cloth under
the rubber feet to prevent this from happen-
ing. If you do so, please make sure that the
unit will not slip or move accidentally.
• Do not put anything that contains water (e.g.,
ower vases) on this unit. Also, avoid the use
of insecticides, perfumes, alcohol, nail polish,
spray cans, etc., near the unit. Swiftly wipe
away any liquid that spills on the unit using a
dry, soft cloth.
• If you will be using the HD-3 in the same loca-
tion for an extended period, we recommend
that you use an optional drum mat (TDM-1)
to prevent the adjuster from discoloration to
the surface
• When setting up or storing the HD-3, be
careful so the ngers 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.
• When moving the HD-3, check the following
points rst, then be sure to keep the system
in the horizontal position while lifting and
carrying it. Take care not to pinch your hand,
or drop the system on your feet.
• Check that the knobs and screws that
fasten the pads, arm pipes, and foot
pipes have not become loose. If any are
loose, tighten them securely.
• Disconnect the AC adaptor.
• Disconnect external devices.
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.
• 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
aect the performance or functionality of the
product, and you may continue using it with
condence.
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 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 that it may not
be possible to restore the data, and Roland
assumes no liability concerning such loss of
data.
Additional Precautions
• 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.
• Never strike or apply strong pressure to the
display.
• 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.
• This instrument is designed to minimize
the extraneous sounds produced when it’s
played. However, since sound vibrations can
be transmitted through oors and walls to
a greater degree than expected, take care
not to allow these sounds to become a
nuisance to neighbors, especially when using
headphones.
• When you need to transport the unit, pack-
age it in the box (including padding) that it
came in, if possible. Otherwise, you will need
to use equivalent packaging materials.
• 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 specications, contact
the manufacturer of the cable.
• Due to the structure of this product, it is
possible for pets or other small animals to
enter the openings of the pedals. If this
should occur, immediately turn o the power,
disconnect the AC adaptor from the outlet,
and consult your dealer or a Roland service
center
• When you operate the pedals, please be
careful not to get your ngers pinched
between the movable part and the panel.
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.
• Synthetic rubber is used in the pads and
cymbals. If you are bothered by the smell of
rubber, please ventilate the room. Do not
place this product near heating equipment.
