Important Notes; Power Supply - Roland PM-03 Owner's Manual

WARNING
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.

IMPORTANT NOTES

Power Supply

• Do not connect this unit to same electrical outlet
that is being used by an electrical appliance that
is controlled by an inverter (such as a refrigerator,
washing machine, microwave oven, or air
conditioner), or that contains a motor. Depending
on the way in which the electrical appliance is
used, power supply noise may cause this unit to
malfunction or may produce audible noise. If it
is not practical to use a separate electrical outlet,
connect a power supply noise filter between this
unit and the electrical outlet.
• 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.
• Although the LED is switched off when the [ON]
switch is switched off, this does not mean that the
unit has been completely disconnected from the
source of power. If you need to turn off the power
completely, first turn off the [ON] switch, then
unplug the power cord from the power outlet. For
this reason, the outlet into which you choose to
connect the power cord's plug should be one that
is within easy reach and readily accessible.
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 interference.
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the
vicinity of this unit. Such noise could occur when
receiving or initiating a call, or while conversing.
Should you experience such problems, you should
relocate such wireless devices so they are at a
greater distance from this unit, or switch them off.

CAUTION
The unit should be located so that its
location or position does not interfere with
its proper ventilation.
Always grasp only the plug on the
power-supply cord when plugging into, or
unplugging from, an outlet or this unit.
At regular intervals, you should unplug the
power plug 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.
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.
• 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.
• When moved from one location to another where
the temperature and/or humidity is very different,
water droplets (condensation) may form inside
the unit. Damage or malfunction may result if you
attempt to use the unit in this condition. Therefore,
before using the unit, you must allow it to stand
for several hours, until the condensation has
completely evaporated.
• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet
may discolor or mar the surface.
You can place a piece of felt or cloth under the
rubber feet to prevent this from happening. If you
do so, please make sure that the unit will not slip or
move accidentally.
• Do not put anything that contains water on this
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.
• Never use benzine, thinners, alcohol or solvents of
any kind, to avoid the possibility of discoloration
and/or deformation.
CAUTION
Never climb on top of, nor place heavy
objects on the unit.
Never handle the power cord or its plugs
with wet hands when plugging into, or
unplugging from, an outlet or this unit.
Before moving the unit, disconnect the
power plug from the outlet, and pull out all
cords from external devices.
Before cleaning the unit, turn it off and
unplug the power cord from the outlet (p. 4).
Whenever you suspect the possibility of
lightning in your area, pull the plug on the
power cord out of the outlet.
Additional Precautions
• Use a reasonable amount of care when using the
unit's controls; and when using its INPUT jacks.
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.
• A small 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.
• 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.
• 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 information on cable specifications,
contact the manufacturer of the cable.
• Due to the structural design of this instrument,
small pets or other animals could end up getting
trapped inside it. If such a situation is encountered,
you must immediately turn off the unit and
disconnect the power cord from the outlet. You
should then consult with the retailer from whom
the instrument was purchased, or contact the
nearest Roland Service Center.
• Do not insert hands, fingers, etc, into the openings
in the unit. In particular, if the unit is to used in
households with small children, always provide
adult supervision to ensure that children keep their
hands and feet out of these openings.
