Guidance and Manufacturer's Declaration - Electromagnetic Immunity
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2,5
GHz
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 CS Bed is used exceeds
the applicable RF compliance level above, the CS Bed should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the CS Bed.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Part No 1153410

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).
