Guidance and manufacturer´s declaration – electromagnetic immunity
The Elipar is intended for use in the electromagnetic environment specified below.
The customer or the user of the Elipar should assure that it is used in such an environment.
IEC 60601 Electromagnetic environment -
Immunity test Compliance level
test level guidance
Portable and mobile RF communications
equipment should be used no closer
to any part of the Elipar, 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

according to the transmitter manu -
facturer and
d is the recommended
separation distance in metres (m). b
Field strengths from fixed RF trans -
mitters, as determined by an electro-
magnetic 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 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 Elipar is used
exceeds the applicable RF compliance level above, the Elipar should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the Elipar.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
