● Do not connect this unit to same electrical outlet that is
being used by an electrical appliance that is controlled
by an inverter (such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that contains a
motor. 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.
