IMPORTANT NOTES

Power Supply: Use of
Batteries
301
• 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.
302
• The AC adaptor will begin to generate
heat after long hours of consecutive
use. This is normal, and is not a cause
for concern.
303a
• If you'll be using the ME-25 for an
extended time, we recommend that
you use an AC adaptor. If you prefer to
use a battery, we recommend an
alkaline battery.
304b
• Batteries should always be installed or
replaced before connecting any other
devices. This way, you can prevent
malfunction and/or damage to speakers
or other devices.
306b
• Batteries are supplied with the unit. The
life of these batteries may be limited,
however, since their primary purpose
was to enable testing.
307
• 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
351
• 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.
352a
• This device may interfere with radio and
television reception. Do not use this
device in the vicinity of such receivers.
352b
• 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.

354a
• 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.
355b
• 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 evapo-
rated.
360
• Depending on the material and temper-
ature 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.
Maintenance
401a
• 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.
402
• Never use benzine, thinners, alcohol or
solvents of any kind, to avoid the possi-
bility of discoloration and/or defor-
mation.
Repairs and Data
452
• 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 on a
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.

Additional Precautions
551
• Please be aware that the contents of
memory can be irretrievably lost as a
result of a malfunction, or the improper
operation of the unit. To protect
yourself against the risk of loosing
important data, we recommend that
you periodically save a backup copy of
important data you have stored in the
unit's memory on a computer.
552
• Unfortunately, it may be impossible to
restore the contents of data that was
stored in the unit's memory or
computer once it has been lost. BOSS/
Roland Corporation assumes no liability
concerning such loss of data.
553
• 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.
556
• 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.
558a
• 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).
559a
• 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 equiv-
alent packaging materials.
562
• Some connection cables contain
resistors. Do not use cables that incor-
porate 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.
