• 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 IEC
test 60601
test level
Conducted 3 Vrms
RF 150 kHz
IEC 61000- to 80
4-6 MHz
Radiated 3 V/m
RF 80 MHz to
IEC 61000- 2.5 GHz
4-3
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 con-
sidered. 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.
Compliance Electromagnetic environment – guidance
level
Not Portable and mobile RF communications equip-
Applicable ment should be used no closer to any part of the
device, including cables, than the recommended
3 V/m separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2
d = 2 .3
where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separa-
tion 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
