IMPORTANT NOTES
291a
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
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.
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.
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 impreg-
nated with a mild, non-abrasive detergent. After-
wards, 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 switches and when using its jacks and
connectors. Rough handling can lead to malfunc-
tions.
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.
558b
• To avoid disturbing your neighbors, try to keep the
unit’s volume at reasonable levels (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.
Copyright
852a
• When exchanging audio signals through a digital
connection with an external instrument, this unit can
perform recording without being subject to the
restrictions of the Serial Copy Management System
(SCMS). This is because the unit is intended solely
for musical production, and is designed not to be
subject to restrictions as long as it is used to record
works (such as your own compositions) that do not
infringe on the copyrights of others. (SCMS is a
feature that prohibits second-generation and later
copying through a digital connection. It is built into
MD recorders and other consumer digital-audio
equipment as a copyright-protection feature.)
853
• 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.
