12 Electromagnetic Emissions and Immunity
* The system is a Class II electrical device, therefore the tests were performed between Line and
Neutral only.
Table12-1.Electromagnetic emissions
The ventilator and Oxygen Mixer are intended for use in the electromagnetic environment specified below. The cus-
tomer or the user of the system should ensure that it is used in such an environment.

Power Line Conducted Emissions
CISPR 11
Group 1
Class B
The ventilator uses RF energy only for its
internal functions. Therefore, its RF
emissions are very low and are not likely
to cause any interference in nearby
electronic equipment.
Radiated RF Emissions
CISPR 11
Harmonic Emissions
IEC 60601-1-2 / IEC 61000-3-2
Class A
The ventilator is suitable for use in all
establishments including domestic
establishments and those directly con-
nected to the public low-voltage power
supply network that supplies buildings
used for domestic purposes.
