Guideline and Manufacturer Declaration – Electromagnetic Immunity
c
In theory the area intensity of stationary transmitters, as for example: 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 regarding stationary transmitters. If the area 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 could be required, as for example: changing the direction or location of
the fabian +nCPAP evolution.
d
Above a Frequency Range of 150kHz to 80MHz the area 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.

For transmitters with a maximum power output not listed in the above table the recommended Safety Distance
(d) in meters (m) can be determined using the equation from the corresponding column, with (P) being the
transmitter’s maximum power output Watts (W) per the transmitter’s manufacturer specifications
REMARK 1 At 80 MHz and 800 MHz the Safety Distance of the Higher frequency applies.
REMARK 2 The ISM bands (industrial, scientific and medical) between 150 kHz and 80 MHz are:
6.765 to 6.795 MHz
13.553 to 13.567 MHz
26.957 to 27.283 MHz
40.66 to 40.7 MHz
REMARK 3 An additional factor of 10 /3 is used when calculating the recommended Safety Distance for
transmitters within the ISM frequency between 150KHz and 80 MHz and between 80MHz and
2.5GHz to reduce the probability of mobile/portable transmitters causing interference if
accidentally brought into the vicinity of the patient.
REMARK 4 These guidelines may not apply to all case. The propagation of electromagnetic quantities is
influenced by Absorption and Reflection of Buildings, Objects and People.
