Electromagnetic interference immunity
Comment 1:
At 80 MHz and 800 MHz, the higher frequency range applies
Comment 2:
These guidelines may not be applicable in all cases. Dissipation of electromagnetic variables is
influenced by absorption and reflection of the buildings, objects and people.
a
The ISM frequency bands (for industrial, scientific and medical applications 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 and 40.66 MHz to
40.70 MHz.
b
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency
range of 80 MHz and 2.5 GHz are intended to reduce the likelihood that portable/mobile communication
devices will be able to cause interference if they are unintentionally brought into the patient area. For this
reason, the additional factor 10/3 is applied in calculating the recommended protection distances in these
frequency ranges.
c
The magnetic force of stationary transmitters, such as base stations of mobile telephones and mobile
terrestrial radio devices, amateur radio stations, AM and FM radio and television transmitter can
theoretically not be determined in advance. To establish the electromagnetic environment with regard to
stationary transmitters, a study of the location should be considered. If the measured magnetic force at the
location at which the
corpuls
3
is used exceeds the above mentioned compliance level, the corpuls
3
must be observed to verify function as intended. If unusual performance characteristics are observed,
additional measures may be required, such as a modified orientation or another location for the
corpuls
3
.
d
The magnetic force must be less than 3 V/m above the frequency range of 150 kHz to 80 MHz.

Recommended protection distances between portable/mobile
HF communication devices and the corpuls
3
The corpuls
3
is intended for operation in an electromagnetic environment in which radiated HF
interference is controlled. The operator or the user of the corpuls
3
can help to prevent
electromagnetic interference by keeping minimum distances between portable/mobile HF
communication devices (transmitters) and the corpuls
3
, as recommended below according to the
maximum output of the communication device.
