can damage the cord, produc-
ing severed elements and short
circuits. Damaged cords are fire
and shock hazards!

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.

Immediately turn the power 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" page when:
• The AC adaptor, the power-
supply cord, or the plug has
been damaged; or
• If smoke or unusual odor oc-
curs
• Objects have fallen into, or
liquid has been spilled onto
the unit; or

WARNING
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.
CAUTION
101b
The unit and the AC adaptor
should be located so their
location or position does not
interfere with their proper venti-
lation.
102c
Always grasp only the plug on
the AC adaptor cord when plug-
ging 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 accu-
mulations 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 insula-
tion and lead to fire.
CAUTION
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

nect the AC adaptor and all
cords coming from external
devices.

Whenever you suspect the pos-
sibility of lightning in your area,
disconnect the AC adaptor from
the outlet.
118a
Should you remove connecter
covers, screw, ground terminal,
and SD cards, keep them in a
safe place out of children's reach,
so there is no chance of them
being swallowed accidentally.
