IMPORTANT NOTES
In addition to the items listed under "USING THE UNIT SAFELY" on page 2–3, please read and
observe the following:
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 condi-
tioner), 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
• The use of an AC adaptor is recommended as the
unit’s power consumption is relatively high.
For battery operation, we recommend the use of
alkaline batteries.
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 interference.
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 communica-
tions 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.
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 evaporated.
360
• 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.
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 possibility of discoloration
and/or deformation.
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
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
BOSS/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 written
down a important data onto paper.
552
• Unfortunately, it may be impossible to restore the
contents of data that was stored in the unit’s
memory once it has been lost. BOSS/Roland
Corporation assumes no liability concerning such
loss of data.
