Guidance and manufacturers declaration—electromagnetic immunity
The Hi Flow is intended for use in the electromagnetic environment specified below. The customer or the user of the Hi Flow should
assure that it is used in such an environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment—guidance
Conducted RF 3Vrms Not Applicable Portable and mobile RF communications equipment should
IEC 61000-4-6 150kHz to 80 MHz Battery powered be used no closer to any part of the Hi Flow,
device including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = 1.2 √P
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
Radiated RF 3 V/m 3 V/m transmitter in watts (W) according to the transmitter
IEC 61000-4-3 80 MHz to 2,5 GHz manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survery

the compliance level in each frequency range

Interference may occur in the vicinity of equipment marked
with the following symbol:
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 asses the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the lo-
cation in which the Hi Flow is used exceeds the applicable RF compliance level above, the Hi Flow should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Hi Flow.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
* This table is included as a standard requirement for equipment which has been tested to specific test levels and over specific frquency
ranges and been found compliant with regulations.
