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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
a
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagne-
tic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the IH 25/1 is used exceeds the applicable RF compliance level above, the IH 25/1 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the IH 25/1.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance Electromagnetic environment – guidance
Group 1 The IH 25/1 uses RF energy only for its internal function. Therefore, its RF emis-
sions are very low and are not likely to cause any interference in nearby electro-
nic equipment.
Class B The IH 25/1 is suitable for use in all establishments, including domestic esta-
blishments and those directly connected to the public low-voltage power supply
Class A
network that supplies buildings used for domestic purposes.

level
Portable and mobile RF communications equipment should be used no closer to any part
of the IH 25/1, including cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1,2
3 V
rms
d = 1,2 80 MHz to 800 MHz
3 V/m
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 fixed RF transmitters, as determined by an electromagnetic site survey,
should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:

Floors should be wood, concrete or cera-
mic tile. If floors are covered with synthetic
material, the relative humidity should be at
least 30 %.
Mains power quality should be that of a typi-
cal commercial or hospital environment.

the user of the IH 25/1 requires continued
operation during power mains interruptions,
it is recommended that the IH 25/1 be pow-
ered from an uninterruptible power supply
or a battery.
