Guideline and manufacturer declaration – electromagnetic immunity
a
The ISM bands (industrial, scientific and medical) between 150 kHz and 80 MHz are:
6.765 MHz to 6.795 MHz
13.553 MHz to 13.567 MHz
26.957 MHz to 27.283 MHz
40.66 MHz to 40.7 MHz
b
The compliance levels in ISM frequency bands between 150 kHz and 80 MHz and between 80 MHz and
2.5 GHz are defined as such so as to decrease the probability of mobile/portable transmitters causing
interference in the event they are accidentally brought in to the vicinity of the patient. For this reason
an additional factor of 10/3 is used when calculating the recommended safety distance of transmitters
in this frequency range.
c
In theory the field intensity of stationary transmitters, as e.g. base units of radio telephones
(mobile/cordless) and mobile land radio devices, amateur radio stations, AM and FM radio stations and
television stations cannot be predefined precisely. A study of the location should be conducted to
determine the electromagnetic environment with regard to stationary transmitters. If the field intensity
at the location where the "fabian +nCPAP evolution" is used exceeds the above compliance levels,
"fabian +nCPAP evolution" should be monitored for proper function. If unusual performance
characteristics are observed, additional measures may be required, as e.g. changing the direction or
location of the "fabian +nCPAP evolution".
d
Above a frequency range of 150kHz to 80MHz the field intensity should be below 10 V/m.
Recommended safety distances between portable and mobile
HF communication devices and the device " fabian +nCPAP evolution "
" fabian +nCPAP evolution " is intended to be operated in an electromagnetic environment with controlled HF
interferences. The operator of the " fabian +nCPAP evolution " can help avoid electromagnetic interference by
maintaining the minimum distance between portable and mobile HF telecommunication devices
(transmitters) and the device " fabian +nCPAP evolution " – depending on the output rating of the
communication device, as listed below.
