AirSep FreeStyle Manuel Du Patient page 220

The FreeStyle is intended for use in the electromagnetic environment specified below. The customer or the user of the FreeStyle should assure that it
is used in such an electromagnetic environment.
IMMUNITY TEST
TEST LEVEL
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
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 FreeStyle is
used exceeds the applicable RF compliance level above, the FreeStyle should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the FreeStyle .
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment ± guidance
Portable and mobile RF communications equipment should be used no closer
to any part of the FreeStyle including cables, than the recommended separation
distance calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
D= 1.2 x √P
D= 1.2 x √P from 80MHz to 800MHz
D= 2.3 x √P from 800MHz to 2.5GHz
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 metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic
a
site survey should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following
