WARNING
Connect mains plug of this model to a mains
socket outlet with a protective earthing
connection.
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
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” 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 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.
This unit should be used only with a rack or stand
that is recommended by Roland.
When using the unit with a rack or stand
recommended by Roland, the rack or stand must
be carefully placed so it is level and sure to remain
stable. If not using a rack or stand, 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.
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 specified on
the AC adaptor’s body. Other AC adaptors may use
a different polarity, or be designed for a different
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 fire and shock
hazards!
This unit, either alone or in combination with an
amplifier 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 allow any objects (e.g., flammable material,
coins, pins); or liquids of any kind (water, soft
drinks, etc.) to penetrate the unit.
Immediately turn the power off, 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.
Batteries must never be recharged, heated, taken
apart, or thrown into fire or water.
Never expose Battery to excessive heat such as
sunshine, fire or the like.
CAUTION
The unit and the AC adaptor should be located so
their location or position does not interfere with
their proper ventilation.
This (KC-110) for use only with Roland stand
ST-A95. Use with other stands (or carts) is capable
of resulting in instability causing possible injury.
Always grasp only the plug on the AC adaptor cord
when plugging into, or unplugging from, an outlet
or this unit.
CAUTION
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 fire.
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

leak and cause damage or injury. In the interest
of safety, please read and observe the following
precautions (p. 4).
• Carefully follow the installation instructions
for batteries, and make sure you observe the
correct polarity.
• Avoid using new batteries together with used
ones. In addition, avoid mixing different types
of batteries.
• Remove the batteries whenever the unit is to
remain unused for an extended period of time.
• If a battery has leaked, use a soft piece of cloth
or paper towel to wipe all remnants of the
discharge from the battery compartment. Then
install new batteries. To avoid inflammation of
the skin, make sure that none of the battery
discharge gets onto your hands or skin.
Exercise the utmost caution so that none of
the discharge gets near your eyes. Immediately
rinse the affected area with running water if any
of the discharge has entered the eyes.
• Never keep batteries together with metallic
objects such as ballpoint pens, necklaces,
hairpins, etc.
Used batteries must be disposed of in compliance
with whatever regulations for their safe disposal
that may be observed in the region in which you
live.

any means. Speaker not user replaceable. Shock
hazardous voltages and currents are present inside
the enclosure.
