IMPORTANT NOTES

291a
In addition to the items listed under "USING THE UNIT SAFELY" on page 2, please read and
observe the following:

Power Supply

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 communi-
cations 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 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 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 write down important data
you have stored in the unit's memory on 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. Roland Corporation
assumes no liability concerning such loss of data.
