Guidance and manufacturer’s declaration – electromagnetic immunity
a: The ISM (industrial, scientific and medical) bands between 0,15 MHz 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 MHz to 40,70 MHz. The
amateur radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz
to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0
MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz.
b: The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency
range 80 MHz to 2,7 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 Insight Infrared Video Goggles is used exceeds the applicable RF compliance level
above, the Insight Infrared Video Goggles should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the
Insight Infrared Video Goggles.
d: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
