80 MHz to 2.7 GHz
c 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 has been incorporated into the formulae used in calculating the
recommended separation distance for transmitters in these frequency ranges.
d 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 [ME EQUIPMENT or ME SYSTEM] is used exceeds the applicable RF compliance level above, the [ME EQUIPMENT or
ME SYSTEM] should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the [ME EQUIPMENT or ME SYSTEM].
e Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
