Important Notes; Additional Precautions - Roland Acoustic Chorus AC-33 Mode D'emploi

IMPORTANT NOTES

Power Supply: Use of Batteries
• 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 malfunc-
tion 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.
• The AC adaptor will begin to generate heat after long hours of
consecutive use. This is normal, and is not a cause for concern.
• When installing or replacing batteries, always turn off 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.
• 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
• 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.
• 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 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.
• 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. Also, do not allow lighting devices that
normally are used while their light source is very close to the unit (such
as a piano light), or powerful spotlights to shine upon the same area
of the unit for extended periods of time. Excessive heat can deform or
discolor the unit.
• 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.
• Do not allow rubber, vinyl, or similar materials to remain on the unit for
long periods of time. Such objects can discolor or otherwise harmfully
affect the finish.
• Do not paste stickers, decals, or the like to this instrument. Peeling
such matter off the instrument may damage the exterior finish.
• 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
• 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.

Additional Precautions

• 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.
• 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.
• 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).
• 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.
• 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.
Copyright
• Recording, duplication, distribution, sale, lease, performance, or broad-
cast of copyrighted material (musical works, visual works, broadcasts,
live performances, etc.) belonging to a third party in part or in whole
without the permission of the copyright owner is forbidden by law.
• Do not use this unit for purposes that could infringe on a copyright
held by a third party. We assume no responsibility whatsoever with
regard to any infringements of third-party copyrights arising through
your use of this unit.
