For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Guidance and manufacturer's declaration – electromagnetic immunity
The IH30 is intended for use in the electromagnetic environment specified below. The customer or the
user of the IH30 should assure that it is used in such an environment.
IMMUNITY IEC 60601
test 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 IH30 is used exceeds the applicable RF compliance level above, the IH30 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the IH30.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment
should be used no closer to any part of the IH30 , inclu-
ding cables, than the recommended separation distance
calculated from the equation applicable to the frequency
of the transmitter.
Recommended separation distance:
d = 1.2
3 Vrms
d = 1.2
d = 2.3
3 V/m
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 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 mar-
ked with the following symbol:
