• Before using this unit, make sure to read the
instructions below, and the Owner’s Manual.
..........................................................................................................
• Do not open or perform any internal modifica-
tions on the unit. (The only exception would be
where this manual provides specific instructions
which should be followed in order to put in place
user-installable options; see Quick Start p. 3.)
..........................................................................................................
• When using the unit with a rack or stand recom-
mended 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.
..........................................................................................................
• 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!
..........................................................................................................
• 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 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.
..........................................................................................................
• Always turn the unit off and unplug the power
cord before attempting installation of the circuit
board (SRX series, SR-JV80 series; Quick Start p.
11).
..........................................................................................................
• Always grasp only the plug on the power-supply
cord when plugging into, or unplugging from, an
outlet or this unit.
..........................................................................................................
• 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 power cord or its plugs with wet
hands when plugging into, or unplugging from,
an outlet or this unit.
..........................................................................................................
• Before moving the unit, disconnect the power
plug from the outlet, and pull out all cords from
external devices.
..........................................................................................................
• Before cleaning the unit, turn off the power and
unplug the power cord from the outlet .
..........................................................................................................
• Whenever you suspect the possibility of lightning
in your area, pull the plug on the power cord out
of the outlet.
..........................................................................................................
• Install only the specified circuit board(s) (SRX
series, SR-JV80 series). Remove only the specified
screws (Quick Start p. 3).
