b. The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in
the frequency range 80 MHz to 2,7 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.
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 YM201is used exceeds
the applicable RF compliance level above, the YM201should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the YM201/YM301.
d. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
