IMPORTANT NOTES
Power Supply
• Do not connect this unit to same
electrical outlet that is being used by
an electrical appliance that is controlled
by an inverter or a motor (such as a
refrigerator, washing machine,
microwave oven, or air conditioner).
Depending on the way in which the
electrical appliance is used, power
supply noise may cause this unit to
malfunction 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.
• To prevent malfunction and equipment
failure, always make sure to turn off the
power on all your equipment before you
make any connections.
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. 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.
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.
• 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.
• Unfortunately, it may be impossible to
restore the contents of data that was
stored in the unit’s memory once it has
been lost. BMB International Corp .
assumes no liability concerning such
loss of data.
• 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.
• Never strike or apply strong pressure to
the display.
• When 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.
• 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.
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.
• Depending on the circumstances of a
particular setup, you may experience a
discomforting sensation, or perceive that
the surface feels gritty to the touch when
you touch this device, microphones
connected to it, or the metal portions of
other objects. This is due to an infinitesimal
electrical charge, which is absolutely
harmless. However, if you are concerned
about this, connect the ground terminal
(see figure) with an external ground. When
the unit is grounded, a slight hum may occur,
depending on the particulars of your
installation.
Unsuitable places for connection
• Water pipes (may result in shock or
electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may
be dangerous in the event of lightning)
• Some connection cables contain
