NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects and people.
(a) 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
Volcano System Family is used exceeds the applicable RF compliance level above, the
Volcano System Family should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Volcano System Family.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
(c)Over the frequency range 5 MHz to 150 MHz, image degradation may be encountered
but complies with IEC 60601-2-37.
