ICS Aircal
Notes on EMC (Electromagnetic Compatibility)
Guidance and manufacturer's declaration - electromagnetic immunity - for equipment and systems that are NOT life-supporting
The ICS Aircal device is intended for use in the electromagnetic environment specified below. The user of the ICS Aircal device should ensure that it is
used in such an environment.
Immunity test
IEC 60601 test level
Compliance level
Electromagnetic environment - guidance
Conducted RF IEC 61000-4-6
3 V rms
150 kHz to 80 MHz
3 V rms
150 kHz to 80 MHz
Portable and mobile RF communications
equipment should be used no closer to any part
of the ICS Aircal device, including cables, than
the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance:
d = 1.2
d = 1.2 for 80 MHz to 800 MHz
d = 2.3 for 80 MHz to 2.5 GHz,
where
P
is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in meters
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,

should be less than the compliance level in each
frequency range

Interference may occur in the vicinity of
equipment marked with this symbol:
Radiated RF IEC 61000-4-3
3 V/m
80 MHz to 2.5 GHz
3 V/m
80 MHz to 2.5 GHz
Note 1: At 80 MHz and 800 MHz the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects
and people.
a.
The ISM (industrial, scientific and medical) bands 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 80 MHz to 2.5 GHz are intended to
decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas.
For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges.
c.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed
RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the ICS Aircal device is
used exceeds the applicable RF compliance level above, the ICS Aircal device should be observed to verify normal operation. If abnormal
performance is observed, additional measures might be necessary, such as reorienting or relocating the ICS Aircal device.
d.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
