Guidance and manufacturer’s declaration – electromagnetic immunity
The Matrix is intended for use in the electromagnetic environment specified below. The customer or user of the Matrix should assure 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 Vrms
150 kHz to 80 MHz
3 V
Portable and mobile RF communications equipment
should be used no closer to any part of the Matrix,
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d 1.17 P =
d 1.17 P =
80 MHz to 800 MHz
d 2.33 P =
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:
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2,5 GHz
3 V/m
Note 1: At 80 MHz and 800 MHz, the higher frequency 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
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 Matrix is used exceeds the applicable RF compliance level above,
the Matrix should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the Matrix.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
