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 television 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 PLATINUM
System is used exceeds the applicable RF compliance level above, the
Dexcom G4 PLATINUM 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 PLATINUM
System.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.
