4.17 Electromagnetic Immunity
The TRIOS system complies with the requirements EN/(IEC) 60601-1-2 (ed. 4.0)
clause 8 Immunity. The test levels for immunity to RF electromagnetic fields are selected
according to general test conditions for medical equipment.
The TRIOS system is intended for use in a Professional Healthcare Facility Environment with
the electromagnetic environment specified below. The user of The TRIOS system should
assure that it is used in such an environment.

Electromagnetic environment – guidelines
Portable and mobile RF communications equipment should be used no closer to any
part of the TRIOS system, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of transmitter.
Recommended separation distance
d = 1,2 √P
d = 1,2 √P 80 MHz to 800 MHz
d = 2,3 √P 800 MHz to 2,7 GHz
where
P
is the maximum output power rating of the transmitter in watts (W) according
to the transmitter manufacture and
d
is the recommended separation distance in meter
(m),
V1
is the conducted RF compliance level, and
E1
is the RF radiated compliance level.
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
(note a, b and c) should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol:
Note 1:
At 80 MHz and 800 MHz, 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, object and people.
Note a:
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 transmitter, an electromagnetic site survey
should be considered. If abnormal performance of the TRIOS system is observed, additional
measures may be necessary, such as re-orienting or relocating the TRIOS system.
Note b:
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Note c:
The ISM (industrial, scientific and medical) bands between 0,15 MHz 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. The amateur radio bands between 0,15 MHz and 80 MHz are
1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz
to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4 MHz,
24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz.

4.18 Distances Between System and Other Equipment
The TRIOS system is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the TRIOS system
can help prevent electromagnetic interference by maintaining a minimum distance
between portable or mobile RF communications equipment (transmitters) and the
TRIOS system as recommended below, according to the maximum output power of the
communication equipment.
