Immunity
Manufacturer's Declaration Electromagnetic Immunity
The Pulmonex is intended for use in the electromagnetic environment specified below. The customer or the user
of the Pulmonex should assure that it is used in such an environment.
Immunity test
IEC 60601-1-2
Test level
Radiated RF 3 V/m,
IEC 801-3:1991 26 MHz to 1000 MHz
Note 1. UT is the a.c. mains voltage prior to application of the test level.
Note 2. At 26 MHz and 1000 MHz, the higher frequency range applies.
Note 3. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflections from structures, objects and people
a Field strength from mixed transmitters, such as base stations for radio telephones and land mobile radios,
amateur radio, AM or FM 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 Pulmonex is used exceeds the applicable RF
compliance levels above, the Pulmonex should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Pulmonex .
b Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.

26 MHz to 1000 MHz equipment should be used no closer to
any part of Pulmonex
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance:
d = 1.2√ P 26 MHz to 1000 MHz
where P is the maximum output power
rating of the transmitter in watt (W)
according to the transmitter manufacturer,
and d is the recommended separation
distance in meters(m)
