Guidance and manufacturer's declaration – electromagnetic immunity
The product is intended for use in the electromagnetic environment specified below. The customer or the user of the product should
assure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
3 V/m
Radiated RF 80 MHz to 2.5 GHz
IEC 61000-4-3
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 considered. If the measured field strength in the location in which the product is used exceeds the applicable RF
compliance level above, the product should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the product.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Compliance level Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be
3 Vrms
used no closer to any part of the product, including cables, than
the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
3 V/m
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
