NOTE 1
NOTE 2
a The ISM (industrial, scientific and medical) bands between 150 kHz and 80
MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957
MHz to 27.283 MHz; and 40.66 to 40.70 MHz.
b The compliance levels in the ISM frequency bands between 150 kHz and 80
MHz and in the frequency range 80 MHz to 2.5 GHz are intended to decrease
the likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 is used in calculating the recommended separation
distance for transmitters in these frequency ranges.
c 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 AED is used exceeds the applicable RF compliance
level above, the AED should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-
orienting or relocating the AED.
d Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 1 V/m.
1-16 Electromagnetic Emissions Standards Compliance
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
