FreeStyle Comfort
Guidance and Manufacturer's Declaration–Electromagnetic Immunity
The FreeStyle Comfort is intended for use in the electromagnetic environment specified below. The customer or
the user of the FreeStyle Comfort should assure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 10 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 10 V/m
IEC 61000-4-3 80 MHz to 2700 MHz
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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
a
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 FreeStyle Comfort
is used exceeds the applicable RF compliance level above, the FreeStyle Comfort should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-ori-
enting or relocating the FreeStyle Comfort.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

closer to any part of the FreeStyle
Comfort, including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.

where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufac-
turer and d is the recommended sepa-
ration distance in metres (m).
Field strengths from fixed RF transmit-
ters, as determined by an electromag-
netic site survey, should be less than
a
the compliance level in each frequency
range.
