Important Notes
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 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 temper-
ature and/or humidity is very different, water droplets (conden-
sation) 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.
Additional Precautions
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 equivalent packaging materials.
561 modified
•
Use only the specified expression pedal (Roland EV-5, BOSS FV-
500L, FV-500H; sold separately). By connecting any other
expression pedals, you risk causing malfunction and/or
damage to the unit.
562
•
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.
