• Immediately turn the power off, remove the

AC adaptor from the outlet, and request ser-
vicing by your dealer or qualified Roland ser-
vice personnel when:
•The AC adaptor or the power-supply cord

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 other-

wise 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 exten-
sion 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, con-

sult with your dealer, or qualified Roland ser-
vice personnel.

......................................................................................................

• 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
(page 9).

......................................................................................................

• Whenever you suspect the possibility of light-

ning in your area, disconnect the AC adaptor
from the outlet.
