IMPORTANT NOTES
Power Supply
• Do not connect this unit to same electrical outlet that
is being used by an electrical appliance that is con-
trolled 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 lter between
this unit and the electrical outlet.
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
• Before connecting this unit to other devices, turn o
the power to all units. This will help prevent malfunc-
tions and/or damage to speakers or other devices.
Power Supply: Use of Batteries
• When installing or replacing batteries, always turn
o the power on this unit and disconnect any other
devices you may have connected. This way, you can
prevent malfunction and/or damage to speakers or
other devices.
• Batteries are supplied with the unit. The life of these
batteries may be limited, however, since their primary
purpose was to enable testing.
• If operating this product on batteries, please use
alkaline batteries or rechargeable Ni-MH batteries.
Placement
• Using the unit near power ampliers (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.
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of
such receivers.
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicin-
ity 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 o.
• 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 dierent, 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.
Repairs and Data
• Please be aware that all data contained in the unit’s
memory may be lost when the unit is sent for repairs.
Important data should always be backed up SD cards,
SDHC cards, Computer, or written down on paper
(when possible). During repairs, due care is taken to
avoid the loss of data. However, in certain cases (such
as when circuitry related to memory itself is out of
order), we regret that it may not be possible to restore
the data, and Roland assumes no liability concerning
such loss of data.
