USING THE UNIT SAFELY
WARNING
012b
Turn off the unit if an abnormality or malfunction
occurs
• Immediately turn the unit 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” sheet when:
• The AC adaptor, the power-supply cord, or the plug has
been damaged; or
• If smoke or unusual odor occurs; 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
Adults must provide supervision in places where
children are present
• When using the unit in locations where children are present,
be careful so no mishandling of the unit can take place. An
adult should always be on hand to provide supervision and
guidance.
014
Do not drop or subject to strong impact
• Protect the unit from strong impact.
(Do not drop it!)
015
Do not share an outlet with an unreasonable
number of other devices
• 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
Do not use overseas
• Before using the unit in overseas, consult with your retailer,
the nearest Roland Service Center, or an authorized Roland
distributor, as listed on the “Information” sheet.
022b
Turn the unit off before removing the video fader
• Always turn the unit off and unplug the AC adaptor before
attempting to remove the video fader (p. 57).
CAUTION
101b
Place in a well ventilated location
• The unit and the AC adaptor should be located so their
location or position does not interfere with their proper
ventilation.
102c
When disconnecting an AC adaptor, grasp it by
the plug
• To prevent conductor damage, always grasp the AC adaptor
by its plug when disconnecting it from this unit or from a
power outlet.
CAUTION
103b
Periodically clean the AC adaptor’s plug
• 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
Manage cables for safety
• 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
Avoid climbing on top of the unit, or placing
heavy objects on it
• Never climb on top of, nor place heavy objects on the unit.

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

Handle the ground terminal carefully
• If you remove the screw from the ground terminal, be
sure to replace it; don’t leave it lying around where it
could accidently be swallowed by small children. When
refastening the screw, make that it is firmly fastened, so it
won’t come loose.
