The IH 40 is intended for use in the electromagnetic environment specified below. The customer or the user of the IH 40 should assure
that it is used in such an environment.

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 40 is used exceeds the applicable RF compliance level above, the IH 40 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 40.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the IH 40
The IH 40 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the IH 40 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF commu-
nications equipment (transmitters) and the IH 40 as recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be deter-
mined using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should be used no closer to any part
of the IH 40, 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 metres (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:
