• Before using this unit, make sure to read the instructions
below, and the Owner’s Manual.
................................................................................................................................................................
002a
• Do not open or perform any internal modifications on
the unit.
................................................................................................................................................................
003
• Do not attempt to repair the unit, or replace parts within
it (except when this manual provides specific instruc-
tions directing you to do so). Refer all servicing to your
retailer, the nearest Roland Service Center, or an autho-
rized Roland distributor, as listed on the “Information”
page.
................................................................................................................................................................
004
• Never use or store the unit in places that are:
• Subject to temperature extremes (e.g., direct sunlight
in an enclosed vehicle, near a heating duct, on top of
heat-generating equipment); or are
• Damp (e.g., baths, washrooms, on wet floors); or are
• Humid; or are
• Exposed to rain; or are
• Dusty; or are
• Subject to high levels of vibration.
................................................................................................................................................................
005
• This unit should be used only with a rack or stand that is
recommended by Roland.
................................................................................................................................................................
006
• When using the unit with a rack or stand recommended
by Roland, the rack or stand must be carefully placed so
it is level and sure to remain stable. If not using a rack or
stand, you still need to make sure that any location you
choose for placing the unit provides a level surface that
will properly support the unit, and keep it from
wobbling.
................................................................................................................................................................
008a
• The unit should be connected to a power supply only of
the type described in the operating instructions, or as
marked on the unit.
................................................................................................................................................................
009
• Do not excessively twist or bend the power cord, nor
place heavy objects on it. Doing so can damage the cord,
producing severed elements and short circuits.
Damaged cords are fire and shock hazards!
................................................................................................................................................................
010
• This unit, either alone or in combination with an
amplifier and headphones or speakers, may be capable
of producing sound levels that could cause permanent
hearing loss. Do not operate for a long period of time at a
high volume level, or at a level that is uncomfortable. If
you experience any hearing loss or ringing in the ears,
you should immediately stop using the unit, and consult
an audiologist.
................................................................................................................................................................
011
• Do not allow any objects (e.g., flammable material, coins,
pins); or liquids of any kind (water, soft drinks, etc.) to
penetrate the unit.
................................................................................................................................................................
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 “Infor-
mation” page.
