System Electromagnetic Immunity Specifications

Immunity Test
Conducted RF
IEC 61000-4-6
(Receiver only)
Radiated RF
IEC 61000-4-3
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 the Dexcom G5 Mobile CGM System is used exceeds the applicable
RF compliance level in the table, the Dexcom G5 Mobile CGM 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 G5 Mobile CGM System.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

Environment Guidance
Level
Floors should be wood, concrete or
ceramic tile. If floors are covered
6 Vrms
with synthetic material, the relative
humidity should be at least 30%.
Recommended Separation Distance
d = 1.2 √P 150 kHz to 80 MHz
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5 GHz
Where P is the maximum output
power rating of the transmitter
in watts (W) according to the
transmitter manufacturer and d
is the recommended separation
distance in meters (m).
10 V/m
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey
be less than the compliance level in
each frequency range
