• Do not allow any objects (e.g., flammable material,
coins, pins); or liquids of any kind (water, soft
drinks, etc.) to penetrate the unit.
..........................................................................................................
012b
• 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
• 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.
..........................................................................................................
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
• Protect the unit from strong impact.
(Do not drop it!)
..........................................................................................................
015
• 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.
..........................................................................................................
016
• 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.
..........................................................................................................

• The unit and the AC adaptor should be located so
their location or position does not interfere with
their proper ventilation.
..........................................................................................................
102c
• Always grasp only the plug on the AC adaptor
cord when plugging into, or unplugging from, an
outlet or this unit.
..........................................................................................................
103b
• Whenever the unit is to remain unused for an
extended period of time, disconnect the AC
adaptor.
..........................................................................................................
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.
..........................................................................................................
107c
• Never handle the AC adaptor or its plugs with
wet hands when plugging into, or unplugging
from, an outlet or this unit.
..........................................................................................................
108d: Selection
• If you need to move the instrument, take note of
the precautions listed below. At least two persons
are required to safely lift and move the unit. It
should be handled carefully, all the while keeping
it level. Make sure to have a firm grip, to protect
yourself from injury and the instrument from
damage.

110b
• Whenever you suspect the possibility of lightning
in your area, disconnect the AC adaptor from the
outlet.
..........................................................................................................

• Should you remove the caps and screws, make
sure to put them in a safe place out of children’s
reach, so there is no chance of them being
swallowed accidentally.
