Electromagnetic propagation is affectedby 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 broadcastcannot be predicted theoretically with accuracy. To assess the electromagnetic environment dueto fixed RF transmitters, an electromagnetic site survey should be considered. If the measured fieldstrength in the location in which the Atria is used exceeds the applicable RF compliance levelabove, then the Atria should be observed to verify normal operation. If abnormal performance isobserved, additional measures may be necessary, such as reorienting or relocating the Atria.bOver the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.c Amplitude modulated at 80% with a modulation frequency of 10 KHz per EN 60601-2-25.11-12 Atria Electrocardiograph Operating Instructions
