• 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.
307
• To prevent malfunction and equipment
failure, always make sure to turn off the
power on all your equipment before you
make any connections.
Placement
351 (QA-EMC)
• 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.

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.

• Depending on the material and temperature
of the surface on which you place the unit,
its rubber feet may discolor or mar the

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.
