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 Dexcom G4 System
is used exceeds the applicable RF compliance level above, the Dexcom
G4 System should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
reorienting or relocating the Dexcom G4 System.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.
