Guidance and manufacturer’s declaration – Electromagnetic Immunity
Hemotek 2 is intended for use in the electromagnetic environment specified below. The costumer
or the user of Hemotek 2 should assure that it is used in such an environment.
Electromagnetic environment - Guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of Hemotek 2, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3 V rms
150 kHz to 80
MHz
3 V/m
80 MHz to 2,5
GHz
Recommended separation distance
d = [ ] =0.28m 0.150 MHz to 80 MHz
d = [ ] = 0.28 m 80 MHz to 800 MHz
d = [ ] =0.56 m 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 metres
(m).
Field strength from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in
each frequency range.
b
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 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 Hemotek 2 is used exceeds the applicable RF compliance level above, Hemotek 2 should
be observed, additional measures may be necessary, such as re-orienting or relocating Hemotek 2.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
