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

EMC Declaration TablesRecommended Separation DistancesRefer to the following table for recommended separation distances betweenthe Atria and portable and mobile RF communications equipment.The Atria is intended for use in an electromagnetic environment in whichradiated RF disturbances are controlled. The user of the Atria can helpprevent electromagnetic interference by maintaining a minimum distancebetween portable and mobile RF communications equipment (transmitters)and the Atria as recommended below, according to the maximum outputpower of the communications equipment.Rated maximum outputpower of transmitterWSeparation distance according to frequency of transmitter150 kHz to 80 MHzd = 1.2 √ P80 MHz to 800 MHzd = 1.2 √ P800 MHz to 2,5 GHzd = 2.3 √ P0,01 0,12 0,12 0,230,1 0,38 0,38 0,731 1,2 1,2 2,310 3,8 3,8 7,3100 12 12 23For transmitters rated at a maximum output power not listed above, therecommended separation distance d in metres (m) can be estimated using theequation applicable to the frequency of the transmitter, where P is the maximumoutput power rating of the transmitter in watts (W) according to the transmittermanufacturer.NOTE1: At 80 MHz and 800 MHz, the separation distance for the higher frequencyrange applies.NOTE 2: These guidelines may not apply in all situations.
