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 RESPONDER 2000 is
used exceeds the applicable RF compliance level above, the RESPONDER 2000 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the RESPONDER 2000.
d
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m.
