Guidance and manufacturer’s declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environments listed below, and should only be
used in such environments:
Immunity test
IEC 60601 test

Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3 Vrms
150 kHz to 80 MHz
3 V/m
80 MHz to 2.5 GHz
Not applicable
3 V/m
Portable and mobile RF communications
equipment should be used no closer to any part
of the 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
80 MHz to 800 MHz
d = 2.3
800 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 metres
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in
each frequency range.
b
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, objects and people.
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 transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
