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 inter-
ference.
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 initi-
ating 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.
354b
• 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.
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.
356
• 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.
359
• Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the
exterior finish.
• During operation, this device must be placed at a distance
of no less than 20 cm from any walls.
101a
• The unit should be located so that its location or
position does not interfere with its proper venti-
lation.

102a
• Always grasp only the plug on the power-supply
cord when plugging into, or unplugging from an
outlet.
..........................................................................................................
103a
• At regular intervals, you should unplug the
power plug and clean it by using a dry cloth to
wipe all dust and other accumulations away from
its prongs. Also, disconnect the power plug from
the power outlet whenever the unit is to remain
unused for an extended period of time. Any
accumulation of dust between the power plug
and the power outlet can result in poor insulation
and lead to fire.
..........................................................................................................
104
• Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be
placed so they are out of the reach of children.
..........................................................................................................
106
• Never climb on top of, nor place heavy objects on
the unit.
..........................................................................................................
107a
• Never handle the power cord or its plug with wet
hands when plugging into, or unplugging from,
an outlet.
..........................................................................................................
108a
• Before moving the unit, disconnect the power
plug from the outlet, and pull out all cords from
external devices.
..........................................................................................................
109a
• Before cleaning the unit, turn off the power and
unplug the power cord from the outlet.
..........................................................................................................
110a
• Whenever you suspect the possibility of lightning
in your area, pull the plug on the power cord out
of the outlet.
..........................................................................................................
119
• The cooling vents on either side of the unit may
become hot, so take care to avoid burns.
..........................................................................................................
120
• Always turn the phantom power off when
connecting any device other than condenser
microphones that require phantom power. You
risk causing damage if you mistakenly supply
phantom power to dynamic microphones, audio
playback devices, or other devices that don’t
require such power. Be sure to check the specifica-
tions of any microphone you intend to use by
referring to the manual that came with it.
(This instrument’s phantom power: 48 V DC, 10 mA Max)
