• 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.
..........................................................................................................
• 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
d e v i c e s . B e e s p e c i a l l y c a r e f u l w h e n u s i n g
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.
..........................................................................................................
• 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.
..........................................................................................................
• Whenever the unit is to remain unused for an
extended period of time, disconnect the AC
adaptor.
..........................................................................................................
• 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 off 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.
