Guidance and manufacturer's declaration – electromagnetic immunity
The IL50 is intended for use in the electromagnetic environment specified below. The customer or
the user of the IL50 should assure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
IEC 61000-4-6 (EN 150 kHz to 80 MHz
61000-4-6)
3 V/m
80 MHz to 2.5 GHz
Radiated RF
IEC 61000-4-3 (EN
61000-4-3)
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 IL50 is used exceeds the applicable RF compliance level above, the IL50 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the IL50.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment – guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of
the IL50, including cables, than the recom-
mended separation distance calculated from
the equation 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
transmitter manufacturer and d is the recom-
mended separation
Distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in
b
each frequency range.
Interference may occur in the vicinity of equip-
ment marked with the following symbol:
