• 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 “Infor-
mation” 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.
................................................................................................
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.
................................................................................................
023
• DO NOT play a CD-ROM disc on a conventional
audio CD player. The resulting sound may be of a
level that could cause permanent hearing loss.
Damage to speakers or other system components may
result.
................................................................................................
101b
• 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
• 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.
................................................................................................
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.

• Before moving the unit, disconnect the AC adaptor
and all cords coming from external devices.
................................................................................................
109b
• Before cleaning the unit, turn off the power and
unplug the AC adaptor from the outlet.
................................................................................................
110b
• Whenever you suspect the possibility of lightning
in your area, disconnect the AC adaptor from the
outlet.
................................................................................................
118a
• Should you remove the ground terminal screw,
keep them in a safe place out of children’s reach, so
there is no chance of them being swallowed
accidentally.
