USING THE UNIT SAFELY
• Before using this unit, make sure to read the
instructions below, and the Owner’s Manual.
..........................................................................................................
• Do not open or perform any internal modifica-
tions on the unit.
..........................................................................................................
•Make sure you always have the unit placed so it is
level and sure to remain stable. Never place it on
stands that could wobble, or on inclined surfaces.
..........................................................................................................
• 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!
..........................................................................................................
• 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.
..........................................................................................................
• Protect the unit from strong impact.
(Do not drop it!)
..........................................................................................................
• 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 grasp only the plug on the power-supply
cord when plugging into, or unplugging from an
outlet.
..........................................................................................................
• 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.
..........................................................................................................
• If the unit could become a hazard if it moves, all
caster wheels should be removed once the unit has
been placed at the place of installation, or has been
loaded onto a vehicle.
..........................................................................................................
• Never climb on top of, nor place heavy objects on
the unit.
..........................................................................................................
• Never handle the power cord or its plug with wet
hands when plugging into, or unplugging from,
an outlet.
..........................................................................................................
• Before moving the unit, disconnect the power
plug from the outlet, and pull out all cords from
external devices.
..........................................................................................................

IMPORTANT NOTES
In addition to the items listed under “IMPORTANT
SAFETY INSTRUCTIONS” and “USING THE UNIT
SAFELY” on pages 2 and 3, please read and observe the
following:
Power Supply
• Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
Placement
• Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this
unit; or move it farther away from the source of inter-
ference.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.
•To avoid possible breakdown, do not use the unit in a wet
area, such as an area exposed to rain or other moisture.
• Do not allow rubber, vinyl, or similar materials to remain
on the unit for long periods of time. Such objects can
discolor or otherwise harmfully affect the finish.
• Do not put anything that contains water (e.g., flower
vases) on the 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.
Maintenance
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.
• Caring for the covering
Clean with a stiff-bristled brush.
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
Additional Precautions
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
internal elements.
•Asmall amount of heat will radiate from the unit during
normal operation.
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
•When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
• Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the
following precautions.
• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level
to be extremely low, or impossible to hear. For infor-
mation on cable specifications, contact the manufac-
turer of the cable.

Connections/Turning On the Power
* To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices
before making any connections.
Turning On/Off the Power
* Once the connections have been completed, turn on power to
your various devices in the order specified. By turning on
devices in the wrong order, you risk causing malfunction and/or
damage to speakers and other devices.
1. Make sure that all volume controls on the PM-3 and
connected devices are set to “0.”
2. Turn on the devices connected to the MAIN INPUT Jacks
and MIX INPUT Jacks.
3. Turn on the PM-3’s [POWER] switch.
* Always make sure to have the volume level turned down before
switching on power. Even with the volume all the way down,
you may still hear some sound when the power is switched on,
but this is normal, and does not indicate a malfunction.
4. Turn on the device connected to the LINE OUTPUT Jacks.
5. Adjust the volume levels for the devices.
* Using a connection cable that contains a resistor can cause the
sound level to be low. Use a connection cable that does not
contain a resistor.
Before switching off the power, lower the volume on each of
the devices in your system and then TURN OFF the devices
in the reverse order to which they were switched on.
