● 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.
..........................................................................................................

● 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
(DIMM; p. 324, p. 326).

● 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.

● Do not put anything that contains water (e.g.,
flower vases) on this unit. Also, avoid the use of
insecticides, perfumes, alcohol, nail polish, spray
cans, etc., near the unit. Swiftly wipe away any
liquid that spills on the unit using a dry, soft cloth.

USING THE UNIT SAFELY
101a
● The unit should be located so that its location or
position does not interfere with its proper venti-
lation.
..........................................................................................................
102b
● Always grasp only the plug on the power-supply
cord when plugging into, or unplugging from, an
outlet or this unit.
..........................................................................................................
103a
● At regular intervals, you should unplug the power
plug 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.
..........................................................................................................
107b
● Never handle the power cord or its plugs with wet
hands when plugging into, or unplugging from, an
outlet or this unit.
..........................................................................................................
108a
● Before moving the unit, disconnect the power plug
from the outlet, and pull out all cords from external
devices.
..........................................................................................................
109a
● Before cleaning the unit, turn off the power and
unplug the power cord from the outlet.
..........................................................................................................
110a
● Whenever you suspect the possibility of lightning
in your area, pull the plug on the power cord out of
the outlet.
..........................................................................................................
115a
● Install only the specified circuit board(s) (DIMM).
Remove only the specified screws (p. 324,
p. 326).
..........................................................................................................
118a
● Should you remove any screws (for the bottom
cover, option cover, and grounding terminal) and
short pin (for the PHONO jacks), keep them in a
safe place out of children's reach, so there is no
chance of them being swallowed accidentally.
