NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects and
people.
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 MHz 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 2,7 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 VS-10S/VS-10M/VS-10H video laryngoscope is used
exceeds the applicable RF compliance level above, the VS-10S/VS-10M/VS-10H
video laryngoscope should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting
