Conducted RF IEC
61000- 4-6 * 150 kHz to 80 MHz
Radiated RF
IEC 61000-4-3 80 MHz to 2.5 GHz
Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: 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 Isolibrium is used exceeds the
applicable RF compliance level above, Isolibrium should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating Isolibrium.
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.

Portable and mobile RF communications
equipment should be used no closer to any
part of Isolibrium, including cables, than
the recommended separation distance
calculated from the equation appropriate for
the frequency of the transmitter.
Recommended Separation Distance
d=1.2√P
d=1.2√P
80 MHz to 800 MHz
d=2.3√P
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, a should be less than the compliance
level in each frequency range.
Interference may occur in the vicinity of
