USING THE UNIT SAFELY
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 “Information”
page.
......................................................................
020
• Keep lithium batteries out of
reach of small children. If a
child has accidentally
swallowed a battery, see a
doctor immediately.
......................................................................
021
• Lithium batteries must never
be recharged, heated, taken
apart, or thrown into a fire or
water.
......................................................................
023
• 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.
......................................................................
027
• Never expose Lithium Battery
to excessive heat such as
sunshine, fire or the like.
101b
• The unit and the AC adaptor
should be located so their
location or position does not
interfere with their proper
ventilation.
.....................................................................
102c
• Always grasp only the plug
on the AC adaptor cord when
plugging into, or unplugging
from, an outlet or this unit.
.....................................................................
103b
• 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 accumu-
lation 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.
.....................................................................
107c
• Never handle the AC adaptor
or its plugs with wet hands
when plugging into, or
unplugging from, an outlet or
this unit.
.....................................................................
108b
• Before moving the unit,
disconnect the AC adaptor
and all cords coming from
external devices.
.....................................................................
109b
• Before cleaning the unit, turn
off the power and unplug the
AC adaptor from the outlet (p.
12).
110b
• Whenever you suspect the
possibility of lightning in your
area, disconnect the AC
adaptor from the outlet.
.....................................................................
111
• If used improperly, batteries
may explode or leak and
cause damage or injury. In
the interest of safety, please
read and observe the
following precautions (p. 16).
• Carefully follow the instal-
lation instructions for
batteries, and make sure
you observe the correct
polarity.
• Remove the batteries
whenever the unit is to
remain unused for an
extended period of time.
• Never keep batteries
together with metallic
objects such as ballpoint
pens, necklaces, hairpins,
etc.
.....................................................................
112
• Used batteries must be
disposed of in compliance
with whatever regulations for
their safe disposal that may be
observed in the region in which you
live.
.....................................................................
113
• Use only the specified type
(model no. CR2025) of
lithium battery (p. 16). Be
sure to insert it as directed (to
ensure correct polarity).
.....................................................................
114
• Used lithium batteries must be
disposed of in compliance
with whatever regulations for
their safe disposal that may
be observed in the region in
which you live.
.....................................................................
118a
• Should you remove the
grounding terminal screw,
lithium battery and battery
case, keep them in a safe
place out of children’s reach,
so there is no chance of them
being swallowed acciden-
tally.
