WARNING
Don't allow foreign objects or liquids to enter
unit; never place containers with liquid on unit
Do not place containers containing
liquid (e.g., flower vases) on this
product. Never allow foreign
objects (e.g., flammable objects,
coins, wires) or liquids (e.g., water or
juice) to enter this product. Doing
so may cause short circuits, faulty
operation, or other malfunctions.
Turn off the unit if an abnormality or malfunction
occurs
Immediately turn the unit 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" sheet when:
• The AC adaptor, the power-supply cord, or
the plug has been damaged; or
• If smoke or unusual odor occurs; or
• 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.
Adults must provide supervision in places where
children are present
Always make sure that an adult is
on hand to provide supervision and
guidance when using the unit in
places where children are present.
Do not drop or subject to strong impact
Protect the unit from strong impact.
(Do not drop it!)
Do not share an outlet with an unreasonable
number of other devices
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.
Do not use overseas
Before using the unit in overseas,
consult with your retailer, the
nearest Roland Service Center, or
an authorized Roland distributor, as
listed on the "Information" sheet.
CAUTION
Place in a well ventilated location
The unit and the AC adaptor should
be located so their location or
position does not interfere with
their proper ventilation.
When disconnecting an AC adaptor, grasp it by the
plug
To prevent conductor damage,
always grasp the AC adaptor by its
plug when disconnecting it from
this unit or from a power outlet.
Periodically clean the AC adaptor's plug
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.
Manage cables for safety
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.
Avoid climbing on top of the unit, or placing heavy
objects on it
Never climb on top of, nor place
heavy objects on the unit.
Do not connect or disconnect the AC adaptor with
wet hands
Never handle the AC adaptor or
its plugs with wet hands when
plugging into, or unplugging from,
an outlet or this unit.
Disconnect everything before moving the unit
Before moving the unit, disconnect
the AC adaptor and all cords
coming from external devices.
Unplug the AC adaptor from the outlet before
cleaning
Before cleaning the unit, turn it off
and unplug the AC adaptor from the
outlet (p. 12).
If there is a possibility of lightning strike,
disconnect the AC adaptor from the outlet
Whenever you suspect the
possibility of lightning in your area,
disconnect the AC adaptor from the
outlet.
USING THE UNIT SAFELY
CAUTION
Keep small items out of the reach of children
To prevent accidental ingestion
of the parts listed below, always
keep them out of the reach of small
children.
• Included Parts
RCA-BNC conversion plug (p. 15)
Handle the ground terminal carefully
If you remove the screw from the
ground terminal, be sure to replace
it; don't leave it lying around where
it could accidently be swallowed by
small children. When refastening
the screw, make that it is firmly fastened, so it
won't come loose.
Take care not to get burned
The area of SDI connectors on the
rear panel may become hot, so take
care to avoid burns.
Precautions concerning use of phantom power
supply
Always turn the phantom power
off when connecting any device
other than condenser microphones
that require phantom power.
You risk causing damage if you
mistakenly supply phantom power to dynamic
microphones, audio playback devices, or other
devices that don't require such power. Be sure
to check the specifications of any microphone
you intend to use by referring to the manual
that came with it.
• This instrument's phantom power:
+48 V DC, 5 mA Max
