(continued)
Note U
At 80 MHz and 800 MHz, the higher frequency range applies.
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 FUJIFILM SonoSite ultrasound
system is used exceeds the applicable RF compliance level above, the FUJIFILM SonoSite ultrasound system should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the FUJIFILM SonoSite ultrasound system.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
