8. Guidelines and manufacturer declarations
Electromagnetic emissions
The UltraNeb ultrasonic nebulizer is designed for operation in the environments described
below� The customer or user of the UltraNeb ultrasonic nebulizer should ensure that it is
used in such an environment�
Guidelines for avoiding, recognizing and rectifying electromagnetic inter-
ference with other devices.
Other electrical or electronic devices should not be operated close to the UltraNeb ultrasonic
nebulizer nor stacked with it� If such an arrangement cannot be avoided, the devices should
be monitored to check for correct operation� The effects can be very varied and in some cases
difficult to recognize on account of the wide range of device functions� Examples:
Group 2
Class B
Class A
Compliant
The UltraNeb ultrasonic nebulizer gener-
ates HF energy internally and conducts it
to the ultrasonic head for the purposes
of creating the aerosol mist� The level of
HF emission is very low� Electronic
devices very near by may, however,
experience interference�
The UltraNeb ultrasonic nebulizer is
suitable for use in all establishments
including domestic establishments, and
those directly connected to a public
power supply network that also supplies
buildings used for residential purposes�
