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.
• The use of an AC adaptor is recommended as the unit's
power consumption is relatively high. Should you prefer
to use batteries, please use the alkaline type.
• To prevent malfunction and equipment failure, always
make sure to turn off the power on all your equipment
before you make any connections.
Power Supply: Use of Batteries

distort / interruptions in the sound may occur at high
volume levels, but this does not indicate a malfunction.
If this occurs, please replace the batteries / use the AC
adaptor (sold separately).

• 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
