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
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 Corsano bracelet is
used exceeds the applicable RF compliance level above, Corsano bracelet should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating Corsano Bracelet.
