Floors should be of wood
or concrete or have ceram-
ic tiles� If the floor has
synthetic material, the rel-
ative humidity of the air
must be at least 30%�

If the user of the UltraNeb
ultrasonic nebulizer
requires continuous oper-
ation including during
interruptions in the mains
supply, powering the
UltraNeb ultrasonic nebu-
lizer from an uninterrupt-
ible power supply or a
battery is recommended�
Power frequency magnetic
fields should have values
typically found in com-
mercial and hospital envi-
ronments�
