Guidance and manufacturer's declaration – electromagnetic immunity
The ME 90 is intended for use in the electromagnetic environment specified below. The customer or the
user of the ME 90 should assure that it is used in such an environment.
IMMUNITY test
Conducted RF IEC 61000-
4-6
Radiated RF IEC 61000-4-3
Conducted RF IEC 61000-

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
ME 90 is used exceeds the applicable RF compliance level above, the ME 90 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the ME 90.

Electromagnetic environment –
guidance
Portable and mobile RF communi-
cations equipment should be used
no closer to any part of the ME 90 ,
including cables, than
the recommended separation
distance calculated from the equa-
tion applicable to the frequency of
the transmitter.
Recommended separation distance
where P is the maximum output
power rating of the transmitter in
watts (W) according to the trans-
mitter manufacturer and d is the
recommended separation Distance
in metres (m).
Power frequency magnetic fields
should be at levels characteristic of
a typical location in a typical com-
mercial or hospital environment.
