Guidance and manufacturer's declaration – electromagnetic immunity
The EN-Dynamic is intended for use in the electromagnetic environment specified below. The customer or the user of the
EN-Dynamic should assure that it is used in such an environment.
Immunity test IEC 60601 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 EN-Dynamic is
used exceeds the applicable RF compliance level above, the EN-Dynamic should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the EN-Dynamic.
b Over the frequency range 15 kHz to 8 MHz, field strengths should be less than 3 V / m.
Compliance level Electromagnetic environment –guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the EN-
Dynamic, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance
3 V d = [3.5/3]√P
d = [3.5/3]√P
3 V/ m
d = [7/3]√P
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).
Field strengths from fixed RF transmitters, as deter-
mined by an electromagnetic site survey,
less than the compliance level in each frequency
range. b Interference may occur in the vicinity of
equipment marked with the following symbol:
