USING THE UNIT SAFELY
001
• Before using this unit, make sure to
read the instructions below, and the
Owner’s Manual.
............................................................................................
002c
• Do not open (or modify in any way) the
unit or its AC adaptor.
............................................................................................
003
• Do not attempt to repair the unit, or
replace parts within it (except when this
manual provides specific instructions
directing you to do so). Refer all
servicing to your retailer, the nearest Roland
Service Center, or an authorized 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 mount adaptor (RAD-50) that is
recommended by Roland.
............................................................................................
006
• When using the unit with a rack mount
adaptor recommended by Roland, the
rack 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.
............................................................................................
008c
• Be sure to use only the AC adaptor
supplied with the unit. Also, make sure
the line voltage at the installation
matches the input voltage specified on
the AC adaptor’s body. Other AC adaptors may
use a different polarity, or be designed for a
different voltage, so their use could result in
damage, malfunction, or electric shock.
............................................................................................
008d
• Take care not to exceed the maximum
rated specifications (100 mA) when
using the DC OUT terminal for the
power supply.
............................................................................................
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.
...........................................................................................
012c
• 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 autho-
rized Roland distributor, as listed on the “Infor-
mation” page when:
• The AC adaptor or the power-supply cord has
been damaged; or
• If smoke or unusual odor occurs
• Objects have fallen into, or liquid has been
spilled onto the unit; or
• The unit has been exposed to rain (or otherwise
has become wet); or
• The unit does not appear to operate normally
or exhibits a marked change in performance.
...........................................................................................
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 unrea-
sonable 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.
101b
• The unit and the AC adaptor should be
located so their location or position
does not interfere with their proper
ventilation.
...........................................................................................
102d
• Always grasp only the output plug or
the body of the AC adaptor when
plugging into, or unplugging from, this
unit or an outlet.
...........................................................................................
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 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.
...........................................................................................
107d
• Never handle the AC adaptor body, or
its output 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.
...........................................................................................
110b
• Whenever you suspect the possibility of
lightning in your area, disconnect the
AC adaptor from the outlet.
...........................................................................................
118c
• Keep any removed screw terminals, the
ground terminal screw, screw terminal
cover, included Euroblock connector,
rubber feet, and card protector attachment screws
safely out of children’s reach so as to prevent
these pieces from being swallowed accidentally
by young children.
