Guidance and manufacturer’s declaration – electromagnetic immunity
The IH30 is intended for use in the electromagnetic environment specied below. The customer or the
user of the IH30 should assure that it is used in such an environment.

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
d = 1.2 80 MHz to 800 MHz
d = 2.3
800 MHz to 2.5 GHz
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 xed 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:
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 aected by
absorption and reection from structures, objects and people.
a
Field strengths from xed 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 xed RF transmitters, an
electromagnetic site survey should be considered. If the measured eld 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, eld strengths should be less than 3 V/m.
